A conventional tailplane in trimmed level flight usually produces
Answer: D
Correct answer: A downward load, which the wing must offset with extra lift
On a conventional layout the centre of gravity is ahead of the wing\'s aerodynamic centre, so the wing lift produces a nose-down moment that the tail must balance with a download. The wing then has to carry the weight plus that download, which raises the induced drag - the trim drag penalty of the conventional arrangement. A canard reverses this: its foreplane lifts upward and shares the weight, which is the aerodynamic argument in its favour.
