Note   For example, the joint Australian and New Zealand Standard AS/NZS 1754:2004, Child restraint systems for use in motor vehicles, would apply to an automotive child restraint system that was manufactured during the time period that this 2004 version of the AS/NZS was in force. However, there are later versions of this standard, for example, dated 2010 and 2013. If an automotive child restraint system was manufactured during the time period that the 2010 standard was in force, then that system would be acceptable for use; and if the automotive child restraint system was manufactured during the time period that the 2013 standard was in force, then that system would also be acceptable for use. In effect, by prescribing the 2004 version of this standard, or later version as applicable, the rule permits the use of this version, or any later version, but not any earlier version, and the version that applies to any specific system is the version that applied at the time the system was manufactured.

                 For subregulation 91.085 (1), this Chapter prescribes requirements relating to an NVIS flight.

Note 1   This Chapter applies to all NVIS flights except those conducted by an Australian air transport operator in a Part 133 operation, and those conducted by an aerial work certificate holder in an aerial work operation: see item 1 of Table 91.035 which, in effect, applies regulation 91.085 to all other NVIS flights.

Note 2   This Chapter applies to NVIS flights conducted by a limited aerial work operator mentioned in Part 138: see item 1 of Table 91.035 and regulation 138.350, whose combined effect is to disapply regulation 91.085 from aerial work operations by aerial work certificate holders, but not from limited aerial work operators.

Note 3   For NVIS equipment requirements: see Division 26.17 of the Part 91 MOS. The effect of item 16 of Table 91.035 is that the Division 26.17 requirements apply to all NVIS flights except NVIS flights conducted as a Part 133 operation. The Part 133 MOS contains the equipment requirements for such flights.

Note 1   It is not an offence to fly below the prescribed minimum heights in the circumstances mentioned in subregulation 91.277 (4) or 91.305 (4).

Note 2   This exemption expires 3 years after commencement: see paragraph 11.230 (1) (b) of CASR. Before it expires, Part 91 will be amended to accommodate the rules in this section without recourse to an exemption.

Note 3   The VMC criteria are contained in section 2.07.

        (3)     If an NVIS operation is conducted:

(a)   below the minimum height for a VFR flight at night, as prescribed under regulation 91.277; or

(b)   below the minimum height for an IFR flight, as prescribed under regulation 91.305;

                 then, subject to subsections (6) and (7), NVIS must be used by each NVIS pilot and each NVIS air crew member who is involved in the operation.

        (4)     If, for subsection (1), an NVIS operation is conducted by a single NVIS pilot as the only NVIS crew member then, subject to subsection (5), the operation must be conducted at or above 1 000 ft AGL.

        (5)     An NVIS operation mentioned in subsection (4) may be conducted below 1 000 ft AGL only if it is:

(a)   operationally necessary; and

(b)   conducted at or above 500 ft AGL; and

(c)   the subject of a detailed risk assessment given to CASA; and

(d)   conducted by an operator who holds a CASA approval under regulation 91.045.

        (6)     If, for subsection (1), an NVIS operation (other than one conducted by a single NVIS pilot as the only NVIS crew member) is conducted below 500 ft AGL in the hover, then, despite any other provision in this Chapter, the pilot in command may do any of the following:

(a)   degoggle as an individual;

(b)   permit all or any particular NVIS air crew member to degoggle;

                 but only if, and for so long as, the degoggling enhances operational safety.

        (7)     If, for subsection (1), in an NVIS operation (other than one conducted by a single NVIS pilot as the only NVIS crew member):

(a)   the performance of the NVIS used by an NVIS pilot or NVIS air crew member is degraded because of extensive illumination in the area being overflown; and

(b)   the continued use of the NVIS in such circumstances is likely to affect operational safety; and

(c)   terrain and obstacles in the area may be visually identified and avoided;

                 then the pilot in command may do any of the following in accordance with procedures in the operations manual:

(d)   degoggle as an individual;

        (1)     Subject to subsection (1A), before commencing a flight, the pilot in command must study:

(a)   authorised weather forecasts and authorised weather reports for:

             (i)  the route to be flown; and

            (ii)  the departure aerodrome, the planned destination aerodrome and any planned alternate aerodrome; and

Note   See also subsection 8.04 (3).

(b)   any other reasonably available weather information that is relevant to the intended operation.

     (1A)     If the information mentioned in paragraph (1) (a) is studied more than 1 hour before commencing the flight, the pilot in command must obtain, and review, an update to that information before the flight begins.

        (2)     For subparagraph (1) (a) (i), the authorised weather forecasts are as follows:

(a)   1 of the following:

             (i)  for an operation at or below 10 000 ft AMSL — a GAF or a GAMET area forecast;

            (ii)  for an operation above 10 000 ft AMSL — a SIGWX forecast;

(b)   a wind and temperature forecast.

        (3)     An authorised weather forecast used to satisfy the requirement under subparagraph (1) (a) (i) must cover the whole period of the flight for which it is to be used.

        (4)     For subparagraph (1) (a) (ii), for an IFR flight to a planned destination aerodrome with an IAP that a pilot is able to conduct, the authorised weather forecasts for the planned destination aerodrome and any planned alternate aerodromes must be an aerodrome forecast or an ICAO landing forecast.

        (5)     For subparagraph (1) (a) (ii), for an IFR flight to a planned destination aerodrome without an IAP, or with 1 or more IAPs none of which a pilot is able to conduct, the authorised weather forecasts must be the following:

(a)   for the planned destination aerodrome — an aerodrome forecast, an ICAO landing forecast, or a GAF or a GAMET area forecast;

(b)   for any planned alternate aerodrome — an aerodrome forecast or an ICAO landing forecast.

     (5A)     However, subsections (4) and (5) do not apply if the IFR flight is a Part 121 operation.

        (6)     An authorised weather forecast used to satisfy the requirement under subparagraph (1) (a) (ii) must be valid for at least 30 minutes before, and 60 minutes after, the planned ETA.

7.03     Flights unable to obtain an authorised weather forecast before departure

        (1)     Despite subsection 7.02 (1), an aircraft may commence a flight if:

(a)   an authorised weather forecast or an authorised weather report for the flight is not available; and

(b)   the pilot in command reasonably considers that the weather conditions at the departure aerodrome will permit the aircraft to return and land safely at the departure aerodrome within 1 hour after take-off.

        (2)     The pilot in command of a flight mentioned in subsection (1) (other than a flight that is a Part 121 operation) must return to the departure aerodrome if:

(a)   the authorised weather forecast required for the planned destination aerodrome is not obtained within 30 minutes after take-off; and

(b)   the pilot in command has not nominated a destination alternate aerodrome if required to do so by subsection 8.04 (3).

        (3)     The pilot in command of a flight that is a Part 121 operation must return to the departure aerodrome if the authorised weather forecasts required to satisfy the requirements under regulation 121.170 of CASR (Flight preparation (Part 121 alternate aerodromes) requirements) are not obtained within 30 minutes after take-off.


CHAPTER 8        FLIGHT PREPARATION (ALTERNATE AERODROMES) REQUIREMENTS

Division 8.1         Purpose and definitions

8.01     Purpose

                 For subregulation 91.235 (1), this Chapter prescribes requirements relating to flight preparation and alternate aerodromes (the flight preparation (alternate aerodrome) requirements).

8.02     Definition of relevant weather conditions

        (1)     Subject to subsection (2), in this Chapter:

relevant weather conditions means the following weather conditions:

(a)   for cloud — more than SCT below the alternate minima;

Note   For alternate minima see section 8.08.

(b)   for visibility — either:

             (i)  less than the alternate minima; or

            (ii)  equal to or more than the alternate minima but with a forecast of at least a 30% probability of fog, mist, dust or any other phenomenon restricting visibility below the alternate minima;

(c)   for wind — a headwind, crosswind or downwind component more than the maximum for the aircraft;

(d)   a thunderstorm or associated severe turbulence, or a forecast of at least a 30% probability of such an event.

        (2)     If flight planning for a flight is based on 1 of the following:

(a)   a TAF3, where the ETA of the flight is within the first 3 hours of the TAF3 validity period (but not if that ETA falls outside the end time (if any) specified for the TAF3 service);

(b)   an ICAO landing forecast;

                 then the definition in subsection (1) may be read as if there were no mention of probabilities in subparagraph (1) (b) (ii) and paragraph (1) (d).

8.03     Definition of relevant IAP

   (1)     In this Chapter:

relevant IAP for an aerodrome outside Australian territory is the IAP that the pilot in command of an aircraft determines has the second lowest minimum altitude of the IAPs that the aircraft is able to conduct at the aerodrome (conductible IAPs).

   (2)     For subsection (1), in determining which conductible IAP has the second lowest minimum altitude, the pilot in command must comply with the following constraints:

(a)   the conductible IAPs that may be considered in determining the IAP with the lowest, and hence the second lowest, minimum altitudes must not both require use of the same radio navigation aid;

Note   Radio navigation aid is a defined term in the CASR Dictionary. An example of this mandatory constraint is an aerodrome that has the following IAPs to a specific runway (from lowest to highest minimum altitude): an ILS with CAT I and CAT II minima that both require the use of a non-associated DME; a VOR that uses the same DME as the ILS; a GNSS with LNAV minima; and an NDB. The CAT II minima cannot be used and, therefore, cannot be the lowest minimum altitude and VOR could not be considered to have the second lowest minimum altitude as it shares a required radio navigation aid with the ILS (namely, the same DME).

(b)   CAT II and CAT III minimum altitudes must not be used in determining altitudes for the relevant IAP.

Division 8.2         Destination alternate aerodromes

8.04     Destination alternate aerodromes — weather

        (1)     Subject to subsection (2), the pilot in command of an aircraft must nominate a destination alternate aerodrome if the ETA at the planned destination aerodrome is during the period that:

(a)   begins 30 minutes before the forecast commencement of relevant weather conditions at the planned destination aerodrome; and

(b)   ends 30 minutes after the forecast ending of relevant weather conditions.

Note   For relevant weather conditions, see section 8.02.

        (2)     If:

(a)   flight planning is based on a TAF3; and

(b)   the ETA at the planned destination aerodrome:

             (i)  is within the first 3 hours of the TAF3 validity; and

            (ii)  does not fall outside the end time (if any) specified for the TAF3 service;

                 then the pilot in command of an aircraft must nominate a destination alternate aerodrome if the ETA is during the period that:

(c)   begins at the forecast commencement of relevant weather conditions at the planned destination aerodrome; and

(d)   ends at the forecast ending of the relevant weather conditions.

        (3)     If the forecast for the planned destination aerodrome required by subparagraph 7.02 (1) (a) (ii) is not available then the pilot in command of an aircraft must nominate a destination alternate aerodrome.

        (4)     Subsections (1) and (2) do not apply if the pilot in command is operating an aircraft under the VFR by day within 50 NM of the departure aerodrome.

        (5)     Subsections (1) and (2) do not apply if:

(a)   relevant weather conditions exist; and

(b)   the pilot in command ensures that sufficient fuel is carried to permit the aircraft to hold at the planned destination aerodrome until the end of the period mentioned in subsection (1) or (2), as the case requires.

        (6)     Subsections (1) and (2) do not apply if:

(a)   relevant weather conditions are forecast to occur on an intermittent or temporary basis; and

(b)   the pilot in command ensures that sufficient fuel is carried to permit the aircraft to hold for:

             (i)  30 minutes — when the forecast is based on a change indicator of INTER; or

            (ii)  60 minutes — when the forecast is based on a change indicator of TEMPO.

        (7)     For subsection (6), if a forecast contains multiple change indicators of INTER or TEMPO, the fuel for holding that is required under paragraph (6) (b) must be that for the most limiting requirement.

        (8)     For subsections (1) and (2), if a forecast includes the change indicator BECMG:

(a)   where the weather conditions within the BECMG element of the forecast represent a deterioration in any of the weather elements within the preceding element of the forecast — the change indication is to be applied from the start of the forecast BECMG period; and

(b)   where the weather conditions within the BECMG element of the forecast represent an improvement in all of the weather elements within the preceding elements of the forecast — the change indication is to be applied from the end of the forecast BECMG period.

8.05     Destination alternate aerodromes — navigation

        (1)     The pilot in command of an aircraft must nominate a destination alternate aerodrome if a flight is an IFR flight by night to a planned destination aerodrome that is:

(a)   not served by an IAP; or

(b)   is served by 1 or more IAPs none of which the pilot in command is able to conduct.

        (2)     For a VFR flight by night, the pilot in command must nominate a destination alternate aerodrome that is within 1 hour’s flight time of the planned destination aerodrome:

(a)   unless:

             (i)  the planned destination aerodrome is served by a ground-based radio navigation aid; and

            (ii)  the aircraft is fitted with the appropriate radio navigation system capable of using the aid; and

           (iii)  the pilot in command is competent in using the aid; or

(b)   unless:

             (i)  the aircraft is fitted with an approved GNSS; and

            (ii)  the pilot in command is competent in using the GNSS.

        (3)     If aircraft navigation is to be conducted using a GNSS receiver certified only to (E)TSO C-129, navigation to a destination alternate aerodrome must be planned using a navigation system other than GNSS.

8.06     Destination alternate aerodromes — aerodrome lighting

        (1)     If a flight is planned to land at night at an aerodrome that only has portable runway lighting, the pilot in command of an aircraft must nominate a destination alternate aerodrome unless reliable arrangements have been made for a qualified and responsible person to:

(a)   attend the aerodrome during the period beginning at least 30 minutes before the ETA, and ending on completion of the aircraft’s landing and taxiing (the landing period); and

(b)   display the portable lighting.

        (2)     If a flight is planned to land at night at an aerodrome with electric runway lighting, but without standby power, the pilot in command must nominate a destination alternate aerodrome unless:

(a)   portable runway lights are available; and

(b)   reliable arrangements have been made for a qualified and responsible person to:

        (4)     The pilot in command of an aircraft fitted with a single VHF radiocommunication system may only nominate an aerodrome with PAL as a destination alternate aerodrome if:

(a)   reliable arrangements have been made for a qualified and responsible person to be in attendance to manually switch on the aerodrome lighting; and

(b)   the aircraft has:

             (i)  a HF radiocommunication system; and

            (ii)  30 minutes of holding fuel.

Note   There is no requirement for a responsible person to be in attendance on the ground. The requirement for holding fuel will allow ground staff to be alerted in the event of a failure of the aircraft’s VHF radiocommunication system.

        (5)     Subsections (1) to (4) do not apply if the pilot in command ensures that sufficient fuel is carried to permit the aircraft to hold until first-light plus 10 minutes.

        (6)     A destination alternate aerodrome nominated in accordance with subsection (2) or (3) is not required to have standby power or portable runway lighting.

        (7)     In this section:

qualified, for a responsible person, means a person who is instructed in, and is competent to display, the standard runway lighting with portable lights.

8.07     Destination alternate aerodromes — restrictions

                 The pilot in command of an aircraft may nominate an aerodrome as a destination alternate aerodrome only if the aerodrome is:

CHAPTER 9        FLIGHT NOTIFICATIONS

9.01     Purpose

                 For subregulation 91.240 (1), this Chapter prescribes requirements relating to flight notifications (flight notification requirements).

Note   Different requirements in this Chapter apply either before a flight, during a flight, or after a flight.

9.02     Flight notification requirements

        (1)     If a flight is 1 of the following:

(a)   an IFR flight;

(b)   a VFR flight in Class C or Class D airspace;

then the pilot in command must submit a flight plan in accordance with procedures published in the authorised aeronautical information.

        (2)     If a VFR flight is 1 of the following:

        (3)     If a VFR flight is a community service flight, the pilot in command must submit a flight plan or nominate a SARTIME for arrival in accordance with procedures published in authorised aeronautical information.

Note   The fact that a flight is not one mentioned in subsection (1), (2) or (3), does not prevent the pilot in command from submitting a flight plan, nominating a SARTIME, or leaving a flight note with a responsible person. However, if a flight plan is submitted, a SARTIME is nominated or a flight note is left with a responsible person, sections 9.03, 9.04 and 9.05 apply.

9.03     Changes to flight plans and SARTIME nominations

        (1)     The pilot in command of an aircraft for a flight where a flight plan has been submitted must ensure that ATS is notified of changes in any of the following:

(b)   the planned departure time (but only if changed by more than 30 minutes);

(c)   the route, landing points and destination alternate aerodromes;

(d)   the SARTIME.

9.04    Cancelling SARTIME

                 The pilot in command of an aircraft for a flight where a SARTIME has been nominated must ensure that the SARTIME is cancelled not later than the time nominated.

9.05     Responsible persons for receipt of a flight note

        (2)     For subsection (1), the responsible person must:

(a)   be over the age of 18 years; and

(b)   have access to at least 2 operative and appropriate means of communicating with a search and rescue service; and

Note   For example, 2 telephones or a telephone and a radio transmitter etc.

(c)   satisfy the pilot in command that the person:

             (i)  knows how to contact JRCC Australia; and

            (ii)  will immediately do so in the event that the pilot in command’s flight is overdue.


CHAPTER 10     MATTERS TO BE CHECKED BEFORE TAKE-OFF

10.01  Purpose

                 For subregulation 91.245 (1), this Chapter prescribes the checks to be carried out before take-off.

10.02  Matters to be checked before take-off

                 The prescribed checks are the following:

(a)   a check to confirm that each aerodrome, air route and airway facility that the pilot plans to use for the flight will be available for use;

(b)   a check of the following:

             (i)  all Head Office and FIR NOTAMs applicable to the en route phase of the flight;

            (ii)  all location-specific NOTAMs for relevant aerodromes;

(c)   a check to confirm the availability of GNSS integrity if required by section 11.03 or 14.06;

(d)   a check to confirm that:

             (i)  all equipment required to be fitted to, or carried on, the aircraft by or under the civil aviation legislation is available and functioning properly; and

            (ii)  emergency and survival equipment carried on the aircraft is readily accessible;

(e)   a check to confirm that each crew member is fit to perform the crew member’s duties;

(f)    a check to confirm that:

             (i)  the aircraft’s hatches, access ports, panels and fuel tank caps are secured; and

            (ii)  the control locks, covers and ground safety devices and restraints have been removed;

(g)   if the aircraft is an Australian aircraft — a check to confirm that there is either:

             (i)  a certificate of release to service for the most recent maintenance carried out on the aircraft; or

            (ii)  a maintenance release for the aircraft;

(h)   a check to confirm that the aircraft’s flight controls have been tested and are functioning correctly;

(i)    for each system fitted to the aircraft for measuring and displaying pressure altitude, a check of the system’s accuracy in accordance with the procedures mentioned in this Chapter;

(j)    if an amount of supplemental oxygen or protective breathing equipment is required by or under the civil aviation legislation to be carried on the aircraft for a flight crew member for the flight — checks to ensure the following (as the case requires):

             (i)  that the required amount of supplemental oxygen is available;

            (ii)  that the protective breathing equipment is operative;

           (iii)  that the oxygen mask is connected to the supply terminal;

           (iv)  that each communication system associated with the oxygen mask is operative;

            (v)  if the oxygen mask is adjustable — that the mask fits the flight crew member correctly.

10.03  Checking systems for measuring and displaying pressure altitude — general

        (1)     For paragraph 10.02 (i), this section sets out the requirements for checking aircraft systems for measuring and displaying pressure altitude (pressure altitude systems).

        (2)     If:

(a)   an aircraft is at a known elevation (the site elevation); and

(b)   an accurate QNH is available;

                 then, before take-off, the pilot in command of the aircraft must check the accuracy of each of the aircraft’s pressure altitude systems in accordance with this section.

Note   For accurate QNH and site elevation — see section 10.06.

10.04  Checking pressure altitude systems — IFR flight

        (1)     The pilot in command of an IFR flight must consider any pressure altitude system with an error in excess of ±75 ft to be inoperative for the flight.

        (2)     If 2 pressure altitude systems are required for the category of operation, then:

(a)   at least 1 system (the first system) must read the site elevation to within 60 ft; and

(b)   if the other system (the second system) has an error between 60 ft and 75 ft — the pilot in command may conduct a flight to the first point of landing where the accuracy of the second system can be rechecked; and

(c)   if, on rechecking, the second system shows an error in excess of 60 ft — the pilot in command must consider the second system to be inoperative for further IFR flight.

        (3)     If 1 pressure altitude system is required for the category of operation, but 2 are fitted, then:

(a)   the pilot in command is permitted to conduct a flight if at least 1 system (the first system) reads the site elevation to within 60 ft; and

(b)   if the other system (the second system) has an error in excess of 75 ft — the pilot in command must consider the second system to be inoperative for further IFR flight.

        (4)     If 1 pressure altitude system is required for the category of operation, and 1 is fitted, then:

(a)   if the system has an error between 60 ft and 75 ft — the pilot in command is permitted to conduct a flight to the first point of landing where the accuracy of the system can be rechecked; and

(b)   if, on rechecking, the system shows an error in excess of 60 ft — the pilot in command must consider the system to be inoperative for further IFR flight.

10.05  Checking pressure altitude systems — VFR flight

        (1)     A pressure altitude system with an accurate QNH is operative for a VFR flight only if the system reads site elevation to within:

(a)   100 ft; or

(b)   at test sites above 3 300 ft — 110 ft.

     (2)     If an aircraft that is fitted with 2 pressure altitude systems continues to conduct a flight under the VFR with 1 of the systems erroneously reading more than 100 ft (or 110 ft as the case may be), the pilot in command must consider the erroneous system to be inoperative for further VFR flight.

        (3)     For an aeroplane operation conducted under the VFR involving flight above FL 200, the pressure altitude system used must be checked against the accuracy requirements for such system usage under the IFR.

10.06  Accurate QNH and site elevation

        (1)     In this Chapter, a QNH is to be considered accurate only if it is provided by 1 of the following:

(a)   AAIS;

(b)   ATC;

(c)   ATIS;

(d)   AWIS;

(e)   CA/GRS;

(f)    WATIR.

        (2)     QNH contained in an authorised weather forecast must not be used for checking the accuracy of a pressure altitude system.

        (3)     Site elevation must be derived from aerodrome survey data that is:

(a)   authorised in writing (as the case requires):

             (i)  by CASA; or

            (ii)  by an NAA; or

(b)   supplied in writing by the relevant aerodrome operator.


CHAPTER 11     AIR TRAFFIC SERVICES — PRESCRIBED REQUIREMENTS

Division 11.1       Use of a class of airspace

11.01  Purpose and definition

        (1)     For subregulation 91.255 (1), this Division prescribes requirements in relation to the use by an aircraft of a class of airspace or a portion of a class of airspace.

        (2)     In this Division:

oceanic airspace means:

(a)   for any airspace within an Australian FIR — the airspace within the lateral boundaries of an oceanic control area described in the AIP; or

(b)   for any airspace not within an Australian FIR — the airspace:

             (i)  described by the relevant NAA as an oceanic control area; or

            (ii)  if subparagraph (i) does not apply — within an area, predominantly over an ocean or sea, where aircraft are unlikely to maintain VHF radiocommunications with an air traffic service.

Note   The effect of subsection (2) is that the vertical limits of an oceanic control area have no relevance to the definition of oceanic airspace within an Australian FIR. At the commencement of this instrument, the AIP document describing the geographic boundaries of oceanic control areas is the Designated Airspace Handbook.

11.02  Transition altitude, transition layer and transition level

        (1)     This section applies to a flight using any class of airspace, whether controlled or uncontrolled, that is within an Australian FIR.

        (2)     The transition altitude is 10 000 ft.

        (3)     The transition level is as set out in Table 11.02 (3), so that for an area QNH mentioned in an item of column 1, the transition level is that mentioned in the same item of column 2.

            Table 11.02 (3) — Transition level

 

Column 1

Column 2

Item

Area QNH

Transition level

1

Equal to, or greater than, 1 013.2 hPa

FL 110

2

At least 997 hPa but less than 1 013.2 hPa

FL 115

3

At least 980 hPa but less than 997 hPa

FL 120

4

At least 963 hPa but less than 980 hPa

FL 125

5

Less than 963 hPa

FL 130

Note   The intention is to retain a minimum buffer of 1 000 ft above the transition altitude.

        (4)     The pilot in command must not cruise within the transition layer.

        (5)     For an operation at or below the transition altitude, the pilot in command must use the following altimeter setting:

(a)   the current local QNH (either an accurate QNH as defined in section 10.06 or a forecast QNH) of a station along the route within 100 NM of the aircraft; or

(b)   if the current local QNH is not known — the current area forecast QNH.

        (6)     For an operation above the transition altitude, the pilot in command must use an altimeter setting of 1 013.2 hPa.

        (7)     On climb, the pilot in command must change between QNH and 1 013.2 hPa after passing 10 000 ft and before levelling off.

        (8)     On descent, the pilot in command must change between 1 013.2 hPa and the QNH before entering the transition layer.

11.03  Oceanic airspace

        (1)     This section applies to a flight in any class of airspace that is oceanic airspace.

Note   Oceanic airspace is defined in section 11.01. At the commencement of this instrument, the AIP document specifying the geographic boundaries of oceanic control areas is the Designated Airspace Handbook.

     (1A)     In this subsection:

INS means inertial navigation system.

IRS means inertial reference system.

long range navigation system, or LRNS, means a navigation system, capable of area navigation in oceanic airspace, that comprises an INS, or an IRS, or an approved GNSS position source.

     (1B)     The pilot in command of an aircraft that has been declared in a flight plan as capable of navigating to a navigation specification that is RNP 2, RNP 4 or RNP 10 must, immediately before entering oceanic airspace, ensure that a check has been completed that the aircraft has at least 2 independent and operative LRNSs capable of navigating to the required navigation specification (capable LRNS).

Note   The requirements of this subsection do not override the minimum navigation system equipment requirements required by the Part 91, Part 121, Part 133 or Part 135 Manual of Standards.

     (1C)     If, as a result of the check mentioned in subsection (1B), the number of capable LRNSs is less than 2, the pilot in command of the aircraft must ensure that ATS is notified of the situation as soon as practicable.

        (2)     Before the departure of a flight planned to operate in oceanic airspace using GNSS, the pilot in command must obtain a prediction for GNSS FDE availability for the intended route.

        (3)     For subsection (2), the pilot in command must plan so that the maximum predicted duration of the loss of GNSS FDE availability is not more than:

(a)   for an RNP-4 operation — 25 minutes; or

(b)   for an RNP-10 operation — 34 minutes.

        (4)     The pilot in command of an aircraft whose approved GNSS can achieve LNAV accuracy of less than 0.3 NM using requisite GNSS satellites may disregard subsections (2) and (3).

Note   Requisite GNSS satellites is defined in section 1.07.

11.04  Loss of GNSS integrity

        (1)     This section applies to a flight in any class of airspace, whether controlled or uncontrolled:

(a)   that is within an Australian FIR; and

(b)   for which the flight is:

             (i)  required to maintain regular contact with an ATS; or

            (ii)  being provided with a separation service by an ATS.

Note   Regulation 91.630 requires certain flights to make regular reports or broadcasts to an ATS. Regulation 91.635 requires certain flights to continuously monitor the primary communications medium used by ATC in controlled airspace.

        (2)     The pilot in command of an aircraft must advise ATS if any of the following occurs:

(a)   during an en route phase of flight — there is RAIM loss or loss of GNSS integrity for more than 5 minutes;

(b)   during a terminal phase of flight — there is RAIM loss or loss of GNSS integrity;

(c)   when ATS requests the provision of GNSS-derived information — RAIM or GNSS integrity is not available;

(d)   when ATS grants a clearance or imposes a requirement based on GNSS-derived information — RAIM or GNSS integrity is not available;

(e)   the GNSS receiver is in dead-reckoning mode, or experiences loss of its navigation function, for more than 1 minute.

        (3)     If a pilot has notified ATS of a RAIM loss or loss of GNSS integrity in accordance with subsection (2), the pilot must notify ATS when RAIM or GNSS integrity is restored.

11.05  Use and supply of distance information

        (1)     This section applies to a flight using any class of airspace, whether controlled or uncontrolled, that is within an Australian FIR.

        (2)     When supplying distance information requested by the ATS, the pilot in command must be satisfied that ATS is aware of the source and the point of reference of the distance measurement.

Note   Here are examples of source and the point of reference: 115 GNSS ML VOR, 80 GNSS CTM NDB, 267 GNSS BEEZA 86 DME BN.

        (3)     When supplying GNSS-derived distance information, the pilot in command must ensure that the information is obtained:

(a)   from an approved GNSS; and

(b)   by reference to data from a valid database.

11.06  ACAS resolution advisory

                 In any class of airspace, whether controlled or uncontrolled, in the event of an ACAS resolution advisory (an RA), the pilot in command of an aircraft must:

(a)   respond immediately by following the RA as indicated, unless doing so would jeopardize the safety of the aircraft; and

(b)   follow the RA even if there is a conflict between the RA and an ATC instruction to manoeuvre; and

(c)   limit the alterations of the flight path to the minimum extent necessary to comply with the RA; and

(d)   promptly return to the last assigned level when the conflict is resolved; and

(e)   notify ATC when returning to the last assigned level.

Note   When this section is complied with, an RA satisfies the requirements of subregulation 91.257 (2) that is, it is a defence to the offence of failing to comply with an ATC clearance or instruction.

11.07  RVSM airspace

        (1)     This section applies to a pilot in command of an aircraft conducting a flight in a class of airspace that is RVSM airspace.

communication services provider, or CSP, means any public or private entity which, under a contract or agreement, provides communication services for general air traffic which may include services provided by a satellite service provider (SSP) or services provided by the CSP in its own capacity as an SSP.

controller-pilot datalink communications, or CPDLC, is the means of communication between ATC and a pilot, using datalink for ATC communications.

datalink operations means aircraft operations using FANS 1/A avionics.

FANS 1/A, which is taken to include FANS 1/A+, is a direct datalink communication between the pilot of an aircraft and ATC via FANS 1/A avionics and FANS 1/A ground end systems, based on EUROCAE ED-100A/RTCA DO-258A, or a later version, as in force from time to time.

performance-based communication, or PBC, means communication based on performance specifications applied to the provision of air traffic services.

performance-based communications and surveillance, or PBCS, means the application of required communication performance (RCP) and required surveillance performance (RSP) specifications to ensure appropriate performance levels for relevant air traffic management operations.

performance-based surveillance, or PBS, means surveillance based on performance specifications applied to the provision of air traffic services.

RCP 240 is the value for the communication expiry time (namely, 240 seconds) after which the initiator of the communication is required to revert to an alternative procedure.

Note   In the context of RCP, the initiator is normally an air traffic controller.

RCP allocation is a portion of an RCP parameter, and is a time value assigned to a specific component of the communication system used for transferring messages between aircraft and ATC.

RCP parameters are performance characteristics that:

(a)   provide the basis for developing an RCP specification; and

(b)   include RCP transaction time, RCP continuity, RCP availability and RCP integrity.

RCP pilot operational response time, or RCP PORT, is an RCP allocation that specifies the maximum time for a flight crew member to recognise and respond to an ATC instruction.

required communication performance, or RCP specification, means the requirements needed to support PBC, being requirements for the following:

(a)   ATC and associated ground equipment;

(b)   the communication service provider;

RSP 180 is the value for the surveillance data delivery time (namely, 180 seconds) at which the surveillance data delivery is considered overdue.

Note   RSP 180 means that 99.9% of surveillance data must be delivered in less than 180 seconds.

RSP allocation is a portion of an RSP parameter and is a time value assigned to a specific component of the communication system used for transferring surveillance reports from aircraft to ATC.

RSP parameters are performance characteristics that:

(a)   provide the basis for developing an RSP specification; and

(b)   include RSP data delivery time, RSP continuity, RSP availability and RSP integrity.

satellite service provider, or SSP, means an entity, or group of entities, that provides the portion of the communication system that involves the operation of 1 or more satellites.

                 Flight plan declaration of capability

        (2)     Before declaring RCP 240 or RSP 180 capabilities on a flight plan, the pilot in command of the aircraft must:

(a)   check with the operator of the aircraft whether the operator has received advice from Airservices Australia that the relevant aircraft has consistently not met the operational criteria of RCP 240 and RSP 180 specifications; and

(b)   if such advice has been received — be reasonably satisfied that the operator of the aircraft has ensured that the aircraft consistently meets the operational criteria of the specifications.

Note   Airservices Australia monitors datalink communications in Australian-administered airspace and advises when operational criteria of RCP 240 and RSP 180 specifications are consistently not met.

        (3)     A declaration must not be made on a flight plan, submitted to ATS for a flight, that the aircraft has RCP capability or RSP capability unless:

(a)   the declaration relates solely to RCP 240 or RSP 180 capabilities; and

(b)   the requirements of subsections (4) to (7) are complied with at the time of the declaration.

Note   It is ultimately a matter for the relevant aviation authority to be satisfied that an aircraft operator’s declaration is, in actual fact, valid for the relevant aircraft at the time of any declaration, audit or inspection. A false declaration would constitute an offence under regulation 11.255 of the Civil Aviation Safety Regulations 1998 and could result in other legal consequences under the Civil Aviation Act 1988.

                 Equipment

        (4)     The aircraft must:

(a)   be equipped with avionics supporting ADS-C and CPDLC applications over FANS 1/A (the equipment); and

(d)   the aircraft system is approved for datalink communications using FANS 1/A avionics: and

(e)   the aircraft datalink system meets the aircraft-allocated requirements of the RCP 240 and RSP 180 specifications.

        (6)     If a document mentioned in paragraph (5) (a), (b) or (c) does not include an SOC, the following may act as a temporary substitute pending the formal issue of the SOC, provided there has been no indication of non-compliance given by the State of Design — a copy of the aircraft operator’s written and dated request to the appropriate design authority for an SOC which indicates the matters mentioned in paragraphs (5) (d) and (e).

Note   Allocation requirements for RCP 240 and RSP 180 specifications are as defined in ICAO Doc 9869, Performance-based Communications and Surveillance (PBCS) Manual.

                 Communication service provider agreement

        (7)     Subject to subsection (8), the pilot in command must be reasonably satisfied that an agreement, or a relevant request under subsection (8), is in place between the aircraft operator and the CSP that includes the following terms and conditions:

(a)   that there is adequate subnetwork coverage in the route flown;

(b)   that there is to be notification of coverage and performance failures;

(c)   that there is to be recording of datalink messages for 30 days;

(d)   that datalink messages mentioned in paragraph (c) will be available on written request by:

(b)   conducting a terminal instrument flight procedure that requires the use of GNSS;

                 then the operation must be conducted using an approved GNSS.

        (4)     If the navigation system being used becomes inaccurate, unreliable or inoperative, the pilot in command must do the following:

(a)   monitor the aircraft’s track by reference to the other navigation aids with which the aircraft is equipped;

(b)   carry out appropriate procedures designed to maintain aviation safety in the event of loss of navigation equipment;

(c)   notify ATS.

        (5)     The pilot in command of an aircraft must ensure that data entered into an area navigation system has:

(a)   for a multi-crew operation — been crosschecked for accuracy by at least 2 flight crew members; or

(b)   for a single-pilot operation — been checked for accuracy by the pilot in command.

        (6)     The pilot in command of an aircraft must ensure that position and tracking information is checked:

(a)   at, or before, each waypoint specified as a reporting point for the flight and published in the authorised aeronautical information or designated by ATS; and

(b)   as far as practicable, at, or before, each en route waypoint published in the authorised aeronautical information; and

(c)   at regular intervals (as far as practicable) during navigation via waypoints not published in the authorised aeronautical information.

        (7)     The pilot in command of an aircraft must ensure that, for a terminal instrument flight procedure in which GNSS will be used as the sole means of navigation:

(a)   the intended procedure is loaded from the navigation database by name; and

(b)   waypoints are not added to, or deleted from, the procedure as so loaded; and

(c)   the navigation system will fly the procedure as published in authorised aeronautical information.

Note   During the conduct of an IAP that is based on a ground-based navigation aid but where GNSS will be used for navigation, pilots should be aware that not all aircraft are capable of conducting reversal or holding procedures, or of navigating DME arcs. The pilot in command should confirm the aircraft navigation system is capable of conducting such operations.

14.03  Instrument approaches — QNH sources

        (1)     Before passing the IAF, the pilot in command must set 1 of the following:

(a)   the actual aerodrome QNH from 1 of the following (an approved source):

             (i)  AAIS;

            (ii)  ATC;

           (iii)  ATIS;

           (iv)  AWIS;

            (v)  CA/GRS;

           (vi)  WATIR;

(b)   the forecast aerodrome QNH;

(c)   the forecast area QNH.

        (2)     The pilot in command must not use an actual aerodrome QNH for an instrument approach more than 15 minutes after receiving it.

        (3)     If the forecast area QNH is used, the pilot in command must increase the minima for the instrument approach by 50 ft.

14.04  GNSS arrivals, and DME or GNSS arrivals

        (1)     During a GNSS arrival, or a DME or GNSS arrival, the pilot in command must:

(a)   use the destination VOR or NDB to provide the primary track guidance; and

(b)   if there is a significant disparity between the track guidance provided by the destination VOR or NDB and the GNSS track indication — discontinue the arrival procedure.

        (2)     For the purposes of paragraph (1) (b), a significant disparity is:

(a)   for an NDB — a divergence of more than 6.9°; and

(b)   for a VOR — a divergence of more than 5.2°.

14.05  Use of GNSS as substitute or alternative to ground-based navigation aids

        (1)     For this section, a ground-based navigation aid is 1 of the following:

(a)   VOR;

(b)   DME;

(c)   NDB;

(d)   Outer Marker;

(e)   Middle Marker.

        (2)     GNSS may be used as a substitute or alternative to a ground-based navigation aid for the procedure or phase of flight mentioned in an item of column 1 of Table 14.05 (2) only if the aircraft is approved for operation under the particular navigation specification shown in the corresponding item in column 2 of the Table.

        (3)     Before using GNSS as a substitute for or alternative to a ground-based navigation aid during an en route phase of flight, the pilot in command must ensure that:

(a)   when a waypoint of the route of the flight that is the ground-based navigation aid is entered into the GNSS — the waypoint is loaded from the navigation database by name; and

(b)   latitude and longitude coordinates for the ground-based navigation aid are not manually entered into the GNSS.

        (4)     GNSS must not be used as a substitute or alternative to a ground-based navigation aid that has been decommissioned.

14.06  Availability of GNSS integrity for instrument approaches

        (1)     Before the departure of a flight that is planned to conduct an IAP that requires the use of GNSS at the planned destination aerodrome or at the destination alternate aerodrome, the pilot in command must obtain a prediction for GNSS integrity availability.

        (2)     For subsection (1), if a continuous loss of GNSS integrity for more than 5 minutes is predicted for any part of the IAP, the pilot in command must revise the flight plan.

Note   Some examples of flight plan revisions include delaying the departure time, planning a different route or providing for an alternate.

        (3)     The pilot in command of a flight that is navigating with SBAS-capable receivers must regularly check for the availability of GNSS integrity indication in areas where the SBAS is not available.

        (4)     The pilot in command of an aircraft whose approved GNSS can achieve LNAV accuracy of less than 0.3 NM using requisite GNSS satellites may disregard subsections (1) and (2).

Note   Requisite GNSS satellites is defined in section 1.07.

14.07  Navigation database requirements

        (1)     In this section:

current, for a navigation database, means that the database is up-to-date in accordance with the AIRAC cycle.

valid, for a navigation database, means that the database must be provided by an approved provider.

        (2)     The data in the navigation database must be:

(a)   valid; and

(b)   subject to subsection (7) — current; and

(c)   in a form that cannot be changed by the operator or a flight crew member.

        (3)     Updating of the navigation database must be carried out in accordance with the instructions issued by the manufacturer of the navigation system.

        (4)     The aircraft operator must ensure that any person updating the navigation database is appropriately qualified and competent to properly perform that task.

        (5)     The operator of an aircraft must:

(a)   regularly check the navigation database for integrity; and

(b)   if any discrepancy in the data is discovered:

             (i)  report the discrepancy as soon as practicable to the approved provider; and

            (ii)  deal with the discrepancy before further operational use by:

(A)  resolving it through the reissue of the database; or

(B)   prohibiting use of the route; or

(C)   ensuring that each flight crew member has instructions on how to preserve the safety of the operation despite the discrepancy.

Note   The Transport Safety Investigation Regulations 2003 have the effect that any discrepancy in the navigation database must be reported if it is likely to cause a hazardous condition from loss of separation between the aircraft and terrain or obstacles, or between the aircraft and other aircraft.

        (6)     If the navigation database changes to the next AIRAC cycle during a flight, the pilot in command must complete the flight using the unchanged database unless to do so will, or is likely to, jeopardise the safety of the flight.

        (7)     Despite paragraph (2) (b), and without affecting subsections (5) and (6), a navigation database:

(a)   that is not current at the start of a flight; or

(b)   that ceases to be current during a flight;

                 may be used for navigation only if:

(c)   data used for navigation of a flight is verified before use by reference to authorised aeronautical information; and

(d)   the database is not used for updating of a navigation system.

        (8)     Despite anything else in this section, an aircraft operated without an MEL must not operate under PBN for more than 72 hours after the navigation database has ceased to be current.

Note   An aircraft that is operated with an MEL must operate in accordance with the instructions in the MEL.

14.08  PRM instrument approach operations

                 The pilot in command of an aircraft must not carry out a PRM approach unless all of the pilots required by the AFM for the conduct of such an approach have received training from an appropriate source that ensures familiarisation with the following:

(a)   the guidance on PRM approaches provided in the AIP;

(b)   the PRM user instructions for the aerodrome of intended operation;

(c)   the relevant instrument approach charts for the aerodrome of intended operation;

(d)   relevant training material available on the websites of Airservices Australia and CASA.

14.09  Instrument approach operational requirements

Note   This section effectively prescribes the requirements for the operation of an aircraft in a specified aircraft performance category at an aerodrome: see regulation 91.320 and section 2.02.

        (1)     When conducting an authorised IAP in IMC, the pilot in command of an aircraft must ensure that the aircraft is operated within the range of, or at not more than the maximum, IAS provided for in subsection (2).

        (2)     For any of the following:

(a)   the specified aircraft performance category for the aircraft that is mentioned in an item of column 1 of Table 14.09 (2);

(b)   a higher specified aircraft performance category than the specified aircraft performance category for the aircraft;

(c)   subject to subsection (3), a lower specified aircraft performance category than the specified aircraft performance category for the aircraft;

                 the aircraft must be operated within the range of speeds, and at not more than the maximum speed (as the case requires), specified in columns 2, 3, 4 and 5 of the same item.

Note   Lower and higher aircraft performance categories are specified in section 2.02. The aircraft performance categories are, from lowest to highest, H, A, B, C, D and E, and in items 1, 2, 3, 4 and 5.

        (3)     For paragraph (2) (c,) the aircraft must not be operated at a lower specified aircraft performance category unless the operator of the aircraft:

(a)   holds an approval under regulation 91.045 for regulation 91.320 to operate in the lower specified aircraft performance category; and

(b)   has complied with subregulation 91.320 (3).

Note 1   For example, an aircraft whose specified aircraft performance category is B, may conform to the requirements of aircraft performance category C. But an aircraft whose specified aircraft performance category is C must not attempt to conform to the requirements of aircraft performance category B without CASA approval and operator compliance with subregulation 91.320 (3).

Note 2   Subregulation 91.320 (3) requires an operator holding the relevant approval to give details of the approval, and the conditions (if any) imposed by CASA on the approval, to the flight crew of an aircraft conducting a flight that uses the approval.

             (i)  a lighting failure has occurred on a runway at a controlled aerodrome; and

            (ii)  doubled spacing of runway edge lights results.

Note   At a controlled aerodrome, in the event of failure of 1 electrical circuit on a runway equipped with interleaved circuitry lighting, pilots will be notified of a doubled spacing of runway edge lights, that is, from 60 m spacing to 120 m spacing.

        (3)     Subject to subsection (5), for an RNP APCH-LNAV, an RNP APCH-LP or another NPA — the minimum altitude must not be below whichever of the following is the highest:

        (7)     For an aerodrome without an authorised IAP, the minimum altitude must not be below the altitude at which the flight can comply with the requirements relating to visual approach approaches published in the authorised aeronautical information for the purposes of subparagraph 91.305 (3) (b) (i).

        (8)     For an aerodrome without an authorised IAP, the minimum visibility must not be below the flight visibility specified for the type of aircraft, the class of airspace and the height in Table 2.07 (3).

Note   Table 2.07 (3) specifies the VMC criteria. The effect of this paragraph is that flight visibility must not be below the highest flight visibility relevant to the aircraft, if it were required to maintain VMC, during the flight to the aerodrome.

15.11  Missed approach

        (1)     During an IAP, the pilot in command of an aircraft must immediately execute the missed approach procedure for the IAP in any of the following circumstances:

(a)   during the final segment of the IAP — if the aircraft is flown outside the navigational tolerance for the navigation aid being used;

(b)   when using GNSS as a substitute or alternative to a ground-based navigation aid — if there is a sustained deviation from the centreline of the IAP other than during a transient manoeuvre;

(c)   when below the MSA — if the navigational aid in use for the IAP becomes unreliable or inoperative;

Note 1   Examples of when a navigational aid for an approach becomes unreliable or inoperative include a RAIM warning for a GNSS approach, a red flag for a VOR approach, or a loss of the ident for an NDB approach.

Note 2   If, after the pilot in command has commenced the missed approach procedure, a RAIM warning ceases or there is no longer loss of data integrity, the pilot may execute the missed approach using GNSS-derived information.

(d)   if the requirements in subsection (2) are not met for the IAP being flown, and the aircraft:

             (i)  for an RNP APCH-LNAV/VNAV, an RNP APCH-LPV, or a precision approach procedure:

(A)  has arrived at the minimum altitude; or

(B)   has passed the minimum altitude but has not touched down; or

            (ii)  for an RNP APCH-LNAV, an RNP APCH-LP or other NPA:

(A)  has arrived at the missed approach point; or

(B)   is being operated below minimum altitude;

(e)   if the aircraft is conducting a circling manoeuvre and:

             (i)  the flight visibility reduces below the minimum visibility; or

            (ii)  an identifiable part of the aerodrome is not distinctly visible to the pilot in command (apart from loss of visibility due to normal aircraft manoeuvring during the approach).

        (2)     For paragraph (1) (d), the requirements are as follows:

(a)   the aircraft must be continuously in a position from which a descent to a landing on the intended runway or, for a rotorcraft, flight to a landing or hover on or over the intended FATO, may be made:

             (i)  at a normal rate of descent; and

            (ii)  using normal manoeuvres; and

           (iii)  that allows touchdown to occur within the TDZ of the runway or TLOF of intended landing;

(b)   for other than low-visibility operations;

             (i)  the flight visibility must be not less than the landing minima; and

            (ii)  at least 1 of the following visual references for the intended runway or FATO must be distinctly visible and identifiable to the pilot in command:

(A)  elements of the approach lighting system;

(B)   the threshold;

(C)   the threshold markings;

(D)  the threshold lights;

(E)   the runway identification lights;

(F)   the FATO itself;

(G)  the visual approach slope indicator;

(H)  the TDZ or TDZ markings;

(I)    the TDZ lights;

(J)    the FATO or runway lights;

Note   There are certain NPAs that have a minimum flight visibility of 5 km, and where the geographical point of attaining the minimum altitude is more than 5 km from the visual references mentioned above. In these instances, noting that the minimum flight visibility is 5 km, if the requirements to conduct a visual approach procedure are met, effectively, the flight transitions from one conducting an IAP, to one conducting a visual approach at the minima.

(c)   for a low-visibility operation, the following visual references for the intended runway must be continuously visible and identifiable to the pilot in command:

             (i)  for a CAT III approach using an FO landing system where use of a DH is prescribed — at least 1 centreline light;

            (ii)  for a CAT III approach utilising an FP landing system — at least 3 consecutive longitudinally-aligned lights;

           (iii)  for a CAT III approach utilising an FO hybrid landing system — at least 3 consecutive longitudinally-aligned lights;

           (iv)  for any other low-visibility operation:

(A)  at least 3 consecutive longitudinally-aligned lights; and

(B)   unless the approach is conducted using a HUD — a lateral element of lighting in the form of an approach lighting crossbar, a landing threshold light, or a barrette of TDZ lights.

        (3)     For paragraph (2) (c), consecutive longitudinally-aligned lights means any of the following:

(a)   centreline lights of the approach lighting system;

(b)   the TDZ lights;

(c)   runway centreline lighting;

(d)   runway edge lights;

(e)   a combination of the lights mentioned in paragraphs (a) to (d).


CHAPTER 16     APPROACH BAN FOR IFR FLIGHTS

16.01  Purpose

        (1)     For subregulation 91.310 (1), this Chapter prescribes circumstances in which an aircraft flown under the IFR must not make an approach to land at an aerodrome.

        (2)     This Chapter applies to an aircraft conducting an IAP at an aerodrome:

(a)   that has an air traffic control service in operation; and

(b)   for which RVR reports are available for IAPs to the relevant runway.

16.02  Approach ban — other than low-visibility operations

        (1)     This section applies to an operation that is not a low-visibility operation.

        (2)     The pilot in command must not descend below 1 000 ft above the aerodrome elevation where the TDZ RVR is reported by ATC as continually less than the landing minima for the IAP.

        (3)     Despite subsection (2), if, after passing 1 000 ft above the aerodrome elevation, the TDZ RVR is reported by ATC as falling below the landing minima, the approach may be continued.

16.03  Approach ban — low-visibility operations

        (1)     This section applies to an operation that is a low-visibility operation.

        (2)     The pilot in command must not descend below 1 000 ft above the aerodrome elevation where a controlling zone RVR is reported by ATC as continually less than the RVR zone requirements.

Note   Controlling zone RVR is defined in section 1.07. An RVR zone is controlling if a report is received from that zone, whether or not it is a required report.

        (3)     Subject to subsection (2), if, after passing 1 000 ft above the aerodrome elevation, a controlling zone RVR is reported by ATC as falling below the RVR zone requirements, the IAP may be continued.

        (4)     For subsections (2) and (3), the RVR zone requirements are as follows:

(a)   a TDZ RVR report is always required, unless:

             (i)  the IAP is a CAT III instrument approach operation conducted with the use of an FO landing system and an FO or FP rollout system; and

            (ii)  the MID and END RVR zones are providing valid reports;

(b)   other than for an SA CAT I instrument approach operation, a MID RVR report is required if the END RVR zone is not providing valid reports;

(c)   other than for an SA CAT I instrument approach operation, an END RVR report is required if the MID RVR is not providing valid reports.

Note   MID or END RVR reports are not required for SA CAT I instrument approach operations.

19.03  General requirements

                 Fuel consumption data

        (1)     When determining the amount of usable fuel required under this Chapter for a flight of an aircraft, the pilot in command must use 1 of the following fuel consumption data sources:

(a)   the most recent aircraft specific fuel consumption data derived from the fuel consumption monitoring system used by the operator of the aircraft (if available);

(b)   the aircraft manufacturer’s data for the aircraft.

Note   The aircraft manufacturer’s data includes electronic flight planning data. The manufacturer’s data may be in the AFM, cruise performance manuals or other publications.

                 Operational requirements etc.

        (2)     In determining the amount of usable fuel required under this Chapter, the pilot in command must take into account the effect of the following matters:

(a)   the operating conditions for the proposed flight, including the following:

             (i)  the actual weight (if known or available), or the anticipated weight, of the aircraft;

            (ii)  relevant NOTAMs;

           (iii)  relevant authorised weather forecasts and authorised weather reports;

           (iv)  relevant air traffic service procedures, restrictions and anticipated delays;

            (v)  the effects of deferred maintenance items and configuration deviations;

(b)   the potential for deviations from the planned flight because of unforeseen factors.

19.04  Amount of fuel that must be carried for a flight

        (1)     The pilot in command of an aircraft must ensure that, when a flight of the aircraft commences, the aircraft is carrying on board at least the following amounts of usable fuel:

(a)   taxi fuel;

(b)   trip fuel;

(c)   destination alternate fuel (if required);

(d)   holding fuel (if required);

(e)   contingency fuel (if applicable);

(f)    final reserve fuel;

(g)   additional fuel (if applicable).

        (2)     The pilot in command must ensure that, at any point of in-flight replanning, the aircraft is carrying on board at least the following amounts of usable fuel:

(a)   trip fuel from that point;

(b)   destination alternate fuel (if required);

(c)   holding fuel (if required);

(d)   contingency fuel (if applicable);

(e)   final reserve fuel;

(f)    additional fuel (if applicable).

        (3)     The pilot in command must ensure that the aircraft is carrying on board at least the following amounts of usable fuel, required at any time to safely continue the flight:

(a)   trip fuel from that time;

(b)   destination alternate fuel (if required);

(c)   holding fuel (if required);

(d)   final reserve fuel;

(e)   additional fuel (if applicable).

        (4)     If, after commencement of the flight, fuel is used for a purpose other than that originally intended during pre-flight planning, the pilot in command must reanalyse the planned use of fuel for the remainder of the flight, and adjust the parameters of the flight in so far as is necessary to remain in compliance with the requirements of this Chapter.

        (5)     Subsection (6) applies if an aircraft for a flight:

(a)   is unable to land at the planned destination aerodrome; and

(b)   diverts to the planned destination alternate aerodrome that was required for the flight.

        (6)     Despite subsection (3), the pilot in command must ensure that the aircraft is carrying at least the following amounts of usable fuel:

(a)   destination alternate fuel from the time of commencing the diversion;

(b)   holding fuel (if required);

(c)   final reserve fuel.

19.05  Procedures for determining fuel before flight and fuel monitoring during a flight

        (1)     The pilot in command of an aircraft for a flight must ensure that the amount of usable fuel on board the aircraft is determined before the flight commences.

        (2)     The pilot in command must ensure that the amount of fuel is checked at regular intervals throughout the flight, and that the usable fuel remaining is evaluated to:

(a)   compare planned fuel consumption with actual fuel consumption; and

(b)   determine the amount of usable fuel remaining; and

(c)   determine whether the remaining usable fuel is sufficient to satisfy:

             (i)  if a point of in-flight replanning has been specified by the pilot in command for the flight and the flight has not proceeded past the point — the requirements of subsection 19.04 (2); and

            (ii)  otherwise — the requirements of subsection 19.04 (3); and

(d)   determine the amount of usable fuel expected to be remaining when the aircraft lands at the destination aerodrome.

19.06  Procedures if fuel reaches specified amounts

        (1)     If, at any time during a flight, the amount of usable fuel remaining in the aircraft on landing at the destination aerodrome will be, or is likely to be, less than the fuel required under subsection 19.04 (3), then the pilot in command must:

(a)   take into account the likely air traffic and operational conditions on arrival at:

             (i)  the destination aerodrome; and

            (ii)  if a destination alternate aerodrome is required for the flight — the destination alternate aerodrome; and

           (iii)  any en route alternate aerodrome; and

(b)   proceed to an aerodrome mentioned in paragraph (a) that enables the pilot in command to continue to meet the requirements in section 19.04.

        (2)     The pilot in command must request from ATS the duration of any likely delay in landing if unforeseen factors could result in the aircraft landing at the destination aerodrome with less than the following amounts of fuel remaining:

(a)   the final reserve fuel;

(b)   the destination alternate fuel (if required).

        (3)     The pilot in command must declare to ATS a “minimum fuel” state if:

(a)   the pilot in command is committed to land the aircraft at an aerodrome in accordance with this section; and

(b)   the pilot in command determines that, if there is any change to the existing ATC clearance issued to the aircraft in relation to that aerodrome, the aircraft will land with less than the final reserve fuel remaining.

Note 1   The declaration of “minimum fuel” informs ATS that all planned aerodrome options have been reduced to a specific aerodrome of intended landing, and any change to the existing clearance may result in landing with less than final reserve fuel. This is not an emergency situation, but an indication that an emergency situation is possible should any additional delay occur.

Note 2   A pilot in command should not expect any form of priority handling because of a “minimum fuel” declaration. ATS will, however, advise the flight crew member of any additional expected delays, and coordinate when transferring control of the aircraft to ensure other ATS units are aware of the aircraft’s fuel state.

        (4)     If, at any time during a flight, the amount of usable fuel remaining in the aircraft on landing at the nearest aerodrome where a safe landing can be made, will be, or is likely to be, less than the final reserve fuel, then the pilot in command must declare a situation of “emergency fuel” by broadcasting “MAYDAY, MAYDAY, MAYDAY FUEL”.

Note   The emergency fuel declaration is a distress message.

19.07  Operational variations — procedures and requirements

        (1)     This section applies only to the following operators (a relevant operator):

(a)   a Part 141 operator or a Part 142 operator;

(b)   an aerial application operator;

(c)   an aerial work operator.

Note   These operators are defined in section 1.07, Definitions.
