ED Decision 2022/005/R
BASIC FUEL SCHEME — PROCEDURES FOR IN-FLIGHT FUEL MANAGEMENT
(a) In-flight fuel checks
(1) The operator should establish a procedure to ensure that in-flight fuel checks are carried out at regular intervals or at specified points indicated in the operational flight plan (one check at least every 60 minutes).
(2) The remaining usable fuel should be evaluated to:
(i) compare the actual consumption with the planned consumption;
(ii) check that the remaining usable fuel is sufficient to complete the flight, in accordance with point (b); and
(iii) determine the usable fuel that is expected to remain upon landing at the destination aerodrome.
(3) In relation to the recording of relevant data, the operator should:
(i) agree with the competent authority on what constitutes relevant data for the purpose of recoding;
(ii) use the relevant data as safety performance indicators (SPIs) of the current fuel scheme; and
(iii) ensure that the recorded data is stored for at least 2 years.
The operator should establish a procedure for the data to be de-identified to a level that ensures the implementation of a ‘just culture’.
(b) In-flight fuel management
(1) The flight should be conducted to ensure that the usable fuel expected to remain upon landing at the destination aerodrome is not less than:
(i) the required alternate fuel plus the FRF; or
(ii) the FRF if no alternate aerodrome is required.
(2) If an in-flight fuel check shows that the usable fuel expected to remain upon landing at the destination aerodrome is less than:
(i) the required alternate fuel plus the FRF, the commander should request delay information from the ATC, and take into account the prevailing traffic and operational conditions at the destination aerodrome, at the destination alternate aerodrome, and at any other adequate aerodrome, to decide whether to proceed to the destination aerodrome or to divert in order to perform a safe landing with not less than the FRF; or
(ii) the FRF, if no destination alternate aerodrome is required, the commander should take appropriate action and proceed to an aerodrome where a safe landing can be made with not less than the FRF.
(c) The use of fuel after flight commencement for objectives other than the ones originally intended during pre-flight planning should require reanalysis and, if applicable, adjustment of the planned operation.
