When can the ground crew manually release the cargo hook?

• A. Only during hook malfunctions
• B. During normal operations on pilot command
• C. Never
• D. On maintenance days

Answer: (A)

The key idea is that the cargo hook’s primary release is controlled by the aircraft crew, but there is a manual ground release as a safety backup. This manual option is intended only when the hook release system fails to operate with normal commands—i.e., during a malfunction. It’s not used during routine operations, and it isn’t something done on maintenance days; those situations follow separate procedures and restrictions. So the ground crew’s ability to manually release the hook is reserved for emergency situations where the standard release cannot be accomplished.
