On an aircraft with folding arms, what must be confirmed after unfolding it for flight?
- A.Arms should remain slightly loose so they can flex in turbulence
- B.Each arm is fully extended and locked securely in its flight position
- C.Only the arms carrying cameras need to be locked
Correct answer
B. Each arm is fully extended and locked securely in its flight position
Why
Folding mechanisms introduce a joint that must be locked before load is applied. An unlocked or partially seated arm can fold or flex in flight and cause loss of control.
