AMC7 CAT.OP.MPA.182 Fuel or energy scheme – aerodrome selection policy - aeroplanes

CAA ORS9 Decision No. 47

Text in magenta in force from 30 October 2025

BASIC FUEL SCHEME WITH VARIATIONS – ISOLATED AERODROME – POINT OF NO RETURN

  1. Unless destination alternate fuel is carried, the operator should regard a destination aerodrome as an isolated aerodrome if the alternate fuel plus the FRF or energy that is required to reach the nearest adequate destination alternate aerodrome is more than:

    1. for aeroplanes with reciprocating engines, the amount of fuel required to fly either for 45 minutes plus 15 % of the flying time planned for cruising, including FRF or energy or for 2 hours, whichever is less; or

    2. for turbine-engined aeroplanes, the amount of fuel required to fly for 2 hours with normal cruise consumption above the destination aerodrome, including the FRF or energy.

  2. If the operator’s fuel planning policy includes an isolated aerodrome, a PNR should be determined by a computerised flight-planning system and specified in the operational flight plan. The required usable fuel for pre-flight calculation should be as indicated in points (b)(1) or (b)(2), whichever is greater:

    1. the sum of:

      1. taxi fuel;

      2. trip fuel from the departure aerodrome to the isolated aerodrome via the PNR;

      3. contingency fuel that is calculated in accordance with the operator’s current fuel scheme;

      4. additional fuel, if required, but not less than:

        1. for aeroplanes with reciprocating engines, the fuel to fly either for 45 minutes plus 15 % of the flight time planned for cruising or for 2 hours, whichever is less; or

        2. for turbine-engined aeroplanes, the fuel to fly for 2 hours with normal cruise consumption above the destination aerodrome, including the FRF or energy;

      5. extra fuel if there are anticipated delays or specific operational constraints; and

      6. discretionary fuel, if required by the commander; or

    2. the sum of:

      1. taxi fuel;

      2. trip fuel from the departure aerodrome to the fuel ERA PNR aerodrome via the PNR;

      3. contingency fuel that is calculated in accordance with the operator’s current fuel scheme;

      4. additional fuel, if required, but not less than:

        1. for aeroplanes with reciprocating engines, fuel to fly for 45 minutes; or

        2. for turbine-engined aeroplanes, fuel to fly for 30 minutes at holding speed at 1 500 ft (450 m) above the fuel ERA aerodrome elevation in standard conditions, which should not be less than the FRF or energy;

      5. extra fuel if there are anticipated delays or specific operational constraints; and

      6. discretionary fuel, if required by the commander.
