Moving the centre of gravity forward makes an aeroplane

  • A.More stable and lighter on the controls
  • B.Unaffected in stability
  • C.More stable but heavier on the controls
  • D.Less stable and lighter on the controls

Answer: C

Correct answer: More stable but heavier on the controls

Moving the centre of gravity forward increases the static margin \( h_n - h \), which makes the moment slope more negative and the aeroplane more resistant to a disturbance in pitch. The same margin sets the stick force per g, so the controls become heavier in the same proportion. Stability and control feel move together: the pilot pays for the added stability in effort, and beyond the forward limit the elevator can no longer produce the nose-up moment needed to flare.
