Consider the following statements about mission fuel fractions:

1. Segment ratios are multiplied to give an overall weight ratio.

2. Cruise and loiter segments are computed from the Breguet equation.

3. The result already includes regulatory reserves.

Which of the statements given above is or are correct?

  • A.1 and 2 only
  • B.1 and 3 only
  • C.2 and 3 only
  • D.1, 2 and 3

Answer: A

Correct answer: 1 and 2 only

Statements 1 and 2 are correct: segment ratios multiply to give the overall weight ratio, and the cruise and loiter segments come from the Breguet range and endurance equations. Statement 3 is the trap - the mission calculation covers the mission only. Reserves, diversion and trapped fuel are added afterwards, typically as a five to ten per cent uplift.
