Statement I: A canard foreplane can be designed to limit the angle of attack the aeroplane reaches.
Statement II: Stalling the foreplane first drops the nose automatically.
In the light of the above statements, choose the correct answer.
Answer: B
Correct answer: Both Statement I and Statement II are correct
Both are true and the second is how the first is achieved. The foreplane is sized and set so that it reaches its stalling angle before the main wing.
When it does, its lift falls, the nose drops, and the angle of attack reduces automatically - the aeroplane cannot be held beyond that point, whatever the pilot does with the stick. The main wing therefore never stalls, and the classic wing drop and departure are avoided. It is a designed-in limit rather than a warning system.
