Discussion
Assertion (A): A canard configuration avoids the trim drag penalty of a tail download.
Reason (R): Its foreplane carries part of the weight rather than pushing downward.
Select the correct answer from the options below.
Answer: C
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason is the cause. A conventional tail trims with a download, so the wing must generate that much lift again on top of the weight, and the induced drag of doing so is the trim drag penalty. A canard foreplane trims with an upload instead, carrying part of the weight and relieving the wing rather than adding to it.
