Static margin is defined as

  • A.The distance from the nose to the centre of gravity
  • B.The difference between forward and aft limits
  • C.The tailplane area divided by the wing area
  • D.The gap to the neutral point, in MAC

Answer: D

A positive static margin means the centre of gravity lies ahead of the neutral point and the aircraft is statically stable. Transports typically carry five to fifteen per cent, while relaxed stability fighters run at or beyond zero.
