Which of the following is NOT true of the design manoeuvring speed VA?
Answer: D
Correct answer: Above it the wing stalls before the structural limit is reached
That has the comparison the wrong way round. Below VA a full control deflection stalls the wing before the limit load factor is reached, which is what makes the manoeuvre safe; above VA the structural limit arrives first, so full deflection can break the aeroplane. The other three statements, including \( V_A = V_s\sqrt{n} \), are correct.
