SECTION 20.7.0



2           APPLICATION

             This section applies to aeroplanes engaged in private, aerial work, charter and regular public transport operations.

3           DEFINITIONS

             Ambient Conditions: Atmospheric temperature, pressure and wind conditions prevailing at a particular aerodrome during the period of 15 minutes preceding the take-off of the aeroplane.

             Forecast Conditions: Atmospheric temperature and pressure conditions forecast for the aerodrome of destination, and its alternate if applicable, by an authorised meteorological officer within:

              (a)  1 hour of the time of take-off of the aeroplane engaged on a flight within Australian Territory; and

              (b)  2 hours of the time of take-off of an aeroplane engaged on an international flight;

             and used for the purpose of determining weight limitations of that aeroplane for landing at that aerodrome on that flight.

             Declared Conditions: Atmospheric temperature, pressure or density altitude conditions declared by CASA as acceptable for a particular aerodrome for the purpose of determining weight limitations for take-off or for landing.

             Declared Weights: Weights determined for the use of declared conditions for a particular aerodrome.

             Developmental Air Service: An air service which due to the nature of operational and economic considerations, has been declared by CASA to be a developmental service.

             Corrected Effective Operational Length: A length of runway — including over-run — expressed in feet, corrected for slope, runway surface, and approaches, declared by CASA as usable for take-off or landing by a particular aeroplane.  For the purpose of computing take-off and landing weights the corrected effective operational length shall be determined by reference to Aeronautical Information Publications, subject to variations contained in NOTAMS.

             Main Runway: The runway with the greatest corrected effective operational length.

             Subsidiary Runway: Any runway on an aerodrome other than the main runway.

4           DECLARED DENSITY ALTITUDE CHARTS  (include in I, 2 and 3)

             Declared density altitude charts are provided as follows:

Winter Season                               Appendix 2

Autumn-Spring Seasons              Appendix 3

             These charts shall be used when weights are determined by the use of declared conditions.
