A crew plans to use hand signals when operating at a distance. What must be true for those signals to work as a CRM tool?
- A.Any commonly understood gesture is fine without discussion
- B.Signals can be invented during the flight as needs arise
- C.Each signal's meaning is agreed and understood by everyone before flight begins
Correct answer
C. Each signal's meaning is agreed and understood by everyone before flight begins
Why
A signal only communicates if sender and receiver share its meaning. Agreeing the set in advance prevents a gesture meant as a warning from being read as an all-clear.
