12 / 20

The fuel plan gives a total trip fuel of 65 US gallons. At the half way point, fuel consumption is 40 US gallons. Given the following information, and assuming that fuel consumption does not change, which statement is correct?

Alternate fuel, including final reserve fuel: 17 US gallons
Contingency fuel: 5% of trip fuel
Usable fuel at departure: 93 US gallons

  • A
    The remaining fuel is not sufficient to reach the destination.
  • B
    At departure the reserve fuel was 28 US gallons.
  • C
    At the destination the required reserves remain intact.
  • D
    At the destination there will still be 30 US gallons in the tanks.

Initially, calculate the Actual Trip Fuel:

  • 40 USG were consumed for half of the trip distance. Therefore, if we assume that Fuel Flow will remain the same, a total of 80 USG of fuel will be required for the whole flight.

According to AMC1 CAT.OP.MPA.195 Fuel/energy scheme — in-flight fuel/energy management policy — helicopters:

(b) in-flight fuel management:

(1) if an in-flight fuel check shows that the usable fuel that is expected to remain upon landing at the destination is less than the required alternate fuel plus the FRF, the commander should:

(i) divert; or

(ii) replan the flight in accordance with point SPA.HOFO.120(b)(1) unless the commander considers it safer to proceed to the destination

So, if our trip fuel is now 80 USG and we took off with a 93 USG usable fuel onboard, the helicopter will be left with only 13 USG.

However, as stated in the question text, Alternate + FRF = 17 USG, which means that the usable fuel that is expected to remain upon landing at the destination is less than the required alternate fuel plus the FRF.

Therefore, "The remaining fuel is not sufficient to reach the destination."
