After an engine failure, the Pilot calculated that a safe landing can be performed after having burnt 400 litres of fuel. If the OEI fuel flow is 280 litres/hour and fuel density is 0.82 kg/l, calculate the fuel amount that must be burnt and how long it is required to burn it.

  • A

    328 kg; 1.4 hours

  • B

    400 kg; 1.4 hr

  • C

    328 kg; 1.17 hr

  • D

    400 kg; 1.17 hr

1. The fuel amount in kg that must burnt for a safe landing is: 400 litres x 0.82 kg/l = 328 kg.

2. After the engine failure, with OEI fuel flow of 280 l/hr, the 400 litres will be burnt in: 400 litres / 280 lt/hr = 1.4 hr.
