(b) is not carried in an approved cargo rack, or in a sealed receptacle; and
(c) is not jettisonable; and
(d) cannot move freely; and
(e) does not extend below the rotorcraft’s landing gear.
Note An example of an operation involving a Class A external load is when a load is carried on a platform from which the load has the potential to fall off if it is not properly secured. See the definition of sealed receptacle which means a belly tank for firefighting, or a cargo pod, basket, bin, or similar thing in which a load can be fully enclosed and sealed.
Class B external load means a load that is not a person, carried by a rotorcraft in an external load operation (which under this MOS is called a Class B external load operation) that is:

(b) jettisonable; and
(c) carried above or below the rotorcraft’s landing gear; and
(d) by using the rotorcraft’s belly hook or winch:
(i) lifted off land or water, or off a structure that is on land or water; and
(ii) carried in flight; and
(iii) set down on land or water, or on a structure that is on land or water.
Note An example of an operation involving a Class B external load is the picking up and carriage, using a sling attached to the belly hook of a rotorcraft, of an air-conditioning unit that is then set down on the roof of a tall building.
Class C external load means a load that is not a person, carried by a rotorcraft in an external load operation (which under this MOS is called a Class C external load operation):

Note 1 An example of an operation involving a Class E external load is a banner towing operation by an aeroplane.
Note 2 Glider towing is excluded from the definition of aerial work operation by paragraph 138.010 (5) (c). Therefore, a glider that is towed by an aeroplane is not a Class E load.
cloud seeding, for a dispensing operation, means the dropping of approved substances from an aeroplane flying though, or above, cloud formations, for the purpose of causing precipitation from the clouds.
emergency service operation has the meaning given by Part 1 of the CASR Dictionary.
ESO means an aerial work operation that is part of an emergency service operation.
Note Emergency service operation is defined in the CASR Dictionary.
ESO operating site means:
(a) a location on ground or water, on a vessel, or on an offshore facility, at or from which an aircraft lands or takes off for the purposes of an ESO, or for training for an ESO; or
(b) a position in the air at which a rotorcraft hovers for carrying out an aerial work operation as part of an ESO or training for an ESO.
Note ESO operating sites are places where an aerial work objective is actually carried out, for example, a clearing or reserve adjacent to a relevant incident site, on to which, or from which, a rotorcraft lands or takes off, or over which it hovers in an ESO external load operation, for the purpose of facilitating a SAR or police operation. ESO operating sites do not include, for example, an aerodrome that is the operator’s normal base, or a hospital or other location which is served by a purpose-built heliport.
ETSO is short for European Technical Standard Order: see the CASR Dictionary.
(E)TSO, followed by an identifying letter and number, is a shorthand reference to both the TSO and the ETSO, each of which has the same identifying letter and number.
external load means a load that is external to an aircraft.
Note An external load is not cargo.
external load operation has the meaning given by regulation 138.010 (2).
Note 1 An external load operation means carrying or towing a load outside an aircraft in flight and includes training for such an operation.
Note 2 An external load operation is not a cargo transport operation.
FATO means final approach and take-off area, as that expression is defined in the CASR Dictionary.
