Schedule 1 Substitution of section 20.7.0 of the Civil Aviation Orders

SECTION 20.7.0

AEROPLANE WEIGHT LIMITATIONS — GENERAL

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:

Summer Season Appendix 1

Winter Season Appendix 2

Autumn-Spring Seasons Appendix 3

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