Discussion
Consider the following pairs of configuration and characteristic:
Conventional tail - Usually carries a download in trim
Canard - Foreplane lifts upward in trim
Tailless - Restoring moment from wing reflex or washout
Canard - Foreplane is stabilising in itself
How many of the pairs given above are correctly matched?
Answer: D
Correct answer: Only three
The first three are right: a conventional tail carries a download in trim, a canard foreplane lifts upward, and a tailless aeroplane obtains its restoring moment from a reflexed trailing edge or from washout on a swept wing. The fourth is wrong. A canard foreplane sits ahead of the centre of gravity and is destabilising in itself, exactly as a wing with an aft centre of gravity is; the stability of a canard layout comes from the main wing behind, and the foreplane is sized to stall first so that the nose drops.
