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
