Refer to figure.
The annex shows the fuel breakdown for a flight from VOGO (Goa) to EGCC (Manchester). The pilots decide to carry an extra 2300 kg of fuel due to weather at the destination. Using a fuel flow of 4.5 tonnes per hour, how much extra holding time in minutes will this extra fuel give at the destination of EGCC, if required?

  • A

    15 min

  • B

    19 min

  • C

    23 min

  • D

    27 min

Refer to figure.
Fuel flow of 4500 kg (4.5 tonnes) per hour is given.

If you check the table, an extra 1000 kg of fuel has a penalty of 236 kg fuel. This means it costs 236 kg of fuel to carry an extra 1000 kg of fuel.

Therefore, an extra 2300 kg of fuel will cause a 2.3 x 236 = 543 kg fuel penalty.
It will leave us 2300 - 543 = 1757 kg of usable fuel for holding.

1757/4500 = 0.39 hours, which, when multiplied by 60, equates to 23 min of fuel burn.
