- ✓ The brake must hold the rated load automatically when power or control is lostCorrect
- C. The overload cut-out must activate before the brake is required to hold any load
- D. The brake must hold the rated load only when manually set by the operator after power loss
Why B is correct
NAVEDTRA 14343 §9-4 states that cargo winch brakes must hold the rated load automatically when power or control is lost. There is no provision for a partial-load standard or a requirement for manual setting after power loss; automatic holding is the stated requirement.
