Fuel Symposium Minimum destination alternate fuel:the « fausse bonne idée »

Capt. Claude Godel

OST 06-3


Minimum destination alternate fuel

  • Present JAR OPS definition of the destination alternate fuel:

  • 1.4Alternate fuel, which should be sufficient for:

    • a.A missed approach from the applicable MDA/DH at the destination aerodrome to missed approach altitude, taking into account the complete missed approach procedure;

    • b.A climb from missed approach altitude to cruising level/altitude;

    • c.The cruise from top of climb to top of descent;

    • d.Descent from top of descent to the point where the approach is initiated, taking into account the expected arrival procedure; and

    • e.Executing an approach and landing at the destination alternate aerodrome selected in accordance with JAR-OPS 1.295.

Minimum destination alternate fuel

Real diversion fuel can be much different from what would be sufficient to fly from the middle of airport A to the middle of airport B.


Minimum destination alternate fuel

The idea of working on a Minimum destination alternate fuel quantity was raised by DGAC France.

OPSG came to OST 06-1 with a proposal of 15 min which would have been in line with the 15 min increase in final fuel when using a flight plan with no alternate.

OST tasked OPSG to continue to work on the issue but suggested that a better result could be achieved by clarifying the definition of the alternate fuel in JAR OPS.

OPSG agreed and finally decided that this could be done by a simple comment to NPA 58 “Terminology and Fuel” during the present public consultation.

There is no more need for NPA 60 which can be cancelled.
