Determine the remaining endurance of the aircraft (ignoring any reserve fuel),

Given:

An aircraft is on a taxi flight, and the fuel gauge is showing 41% of fuel left in the tank.
Total Fuel capacity 514 l
Fuel consumption 190 l/h

  • A

    1 h 07 min

  • B
    1 h 11 min
  • C

    2 h 13 min

  • D
    2 h 43 min

The fuel gauge is showing 41% of fuel in the tank. The total fuel capacity is 514 l.
Therefore, the fuel left is (l) = 41% of 514 l = 211 l

Fuel consumption = 190 l/h

Endurance is the amount of time an aircraft can stay in the air with one load of fuel.

  • Endurance = 211 l ÷ 190 l/h = 1 h 7 min
