Chapter 7—Fuel requirements

Division 1—Preliminary

7.01  Scope of Chapter 7
  This Chapter:
 (a) is made for subregulation 121.235(1) of CASR; and
 (b) prescribes requirements relating to fuel for aeroplanes.

7.02  Definition of destination alternate fuel

Destination alternate aerodrome
 (1) If a destination alternate aerodrome is required for a flight of an aeroplane, the destination alternate fuel is the amount of fuel required to:
 (a) perform a missed approach at the destination aerodrome; and
 (b) climb to the expected cruising altitude; and
 (c) fly the expected routing to the destination alternate aerodrome; and
 (d) descend to the point where the expected approach is initiated; and
 (e) conduct the approach; and
 (f) land at the destination alternate aerodrome.

If there are 2 destination alternate aerodromes
 (2) If 2 destination alternate aerodromes are required for a flight of the aeroplane, the destination alternate fuel is the amount of fuel required to enable the aeroplane to proceed to the destination alternate aerodrome that requires the greater amount of destination alternate fuel under subsection (1).

No destination alternate aerodrome
 (3) If the aeroplane is operated without a destination alternate aerodrome (other than because the planned destination aerodrome is an isolated destination aerodrome), the destination alternate fuel is the amount of fuel required to enable the aeroplane to fly for 15 minutes at holding speed at 1 500 ft above the destination aerodrome elevation in ISA conditions.

Planned destination aerodrome that is isolated
 (4) If the planned destination aerodrome for a flight of the aeroplane is an isolated destination aerodrome, the destination alternate fuel is the amount of fuel required to enable the aeroplane:
 (a) for a piston-engine aeroplane—to fly for 45 minutes plus 15% of the flight time planned to be spent at cruising levels, including final reserve fuel, or 2 hours, whichever is less; and
 (b) for a turbine-engine aeroplane—to fly for 2 hours at normal cruise consumption above the isolated destination aerodrome, including final reserve fuel.

7.03  Definition of contingency fuel
 (1) The contingency fuel for an aeroplane and a flight, is the amount of fuel required to compensate for unforeseen factors, which must not be less than the amount required under subsection (2) or (3).
 (2) Subject to subsection (3), contingency fuel must include:
 (a) either:
 (i) 5% of the trip fuel to the planned destination aerodrome, in the case of a turbine-engine aeroplane; or
 (ii) 10% of the trip fuel to the planned destination aerodrome, in the case of a piston-engine aeroplane; but
 (b) not less than the amount of fuel required to fly, in ISA conditions, for 5 minutes at the holding speed at 1 500 ft above the planned destination aerodrome.
