Which of the following is not a reason for the forward centre of gravity limit?

  • A.Elevator power needed to flare
  • B.Elevator power needed to rotate on take-off
  • C.Trim capability at approach speed
  • D.Insufficient static margin

Answer: D

Correct answer: Insufficient static margin

An insufficient static margin is what sets the *aft* limit, not the forward one - forward of the neutral point the margin only grows. The forward limit is set by control power: enough elevator to rotate on take-off, to flare at touchdown, and to trim at approach speed, all with the nose heavy and the tail carrying its largest download.
