The tailplane contributes to longitudinal stability by

  • A.Increasing the total lift of the aeroplane
  • B.Reducing the wing's induced drag
  • C.Moving the aerodynamic centre forward
  • D.Producing a restoring moment through its distance behind the centre of gravity

Answer: D

An increase in angle of attack raises the tail's lift, and its long moment arm turns that into a substantial nose down moment. The leverage matters as much as the tail's area, which is why the two are combined into a single volume ratio.
