If the aircraft was loaded with the Centre of Gravity in front of the forward CG limit, counteracting the nose-pitching-down moment will lead to…

  • A
    increased manoeuvrability.
  • B
    a lower stalling speed.
  • C
    increased drag.
  • D
    decreased required landing distances.

Refer to figure.
The stick force required to maintain level flight with a forward CG is considerably more than it is with a neutral CG, because the aeroplane is nose-heavy. Forward CG means that we have a longer arm between CG and CP where lift acts. However, the distance between CG and the tail is not increased by the same proportion. Therefore tailplane needs to produce more downforce LT (drag) to balance.

This means that when the centre of gravity is moved beyond its forward limit, drag is increased. This drag increase causes the range of the aircraft to decrease.
