Fuel Planning

Commercial flight

For ICAO Annex 6, Part I, section 4.3.6 "Fuel Requirements," airplanes should calculate their required fuel quantity as follows(see below for actual ICAO text):

  • Taxi fuel
  • Trip fuel (to reach intended destination)
  • Contingency fuel (higher of 5% of "trip fuel" or 5 minutes of holding flight)
  • Destination alternate fuel (to fly a missed and reach an alternate)
  • Final reserve fuel (45 minutes of holding flight for reciprocating engines, 30 minutes for jets)
  • Additional fuel (if needed to guarantee ability to reach an alternate with an engine failure or at lower altitude due to a pressurization loss)
  • Extra fuel (at your discrection)
  • Wind component (head wind, cross wind and tail wind)

N.B Trip fuel must be adjusted to account for any additional fuel that would be required for known ATS restrictions that would result in delayed climb to or early descent from planned cruising altitude.

General Aviation

For general aviation, ICAO Annex 6 Part II, section "Fuel and oil supply" requires:

  • For IFR, enough fuel to reach destination, then alternate (if required), plus 45 minutes
  • For day VFR, enough fuel to reach destination plus 30 minutes
  • For night VFR, enough fuel to reach destination plus 45 minutes

Maximum fuel

Keep in mind that although an aircraft can carry lots of fuel, you need to make sure that the maximum take-off weight is not exceeded.
