Question 397Electricity & Electronics - QMED

The correct answer is D) a spring set brake. In the event of a power failure during cargo loading operations, an electric powered cargo winch will be stopped by a spring set brake. This type of brake is designed to automatically engage when the power is lost, preventing the uncontrolled movement of the cargo. The spring set brake is a safety feature required by regulations to ensure the safe operation of cargo handling equipment, even in the event of a power failure. The other options are incorrect because: A) a hand operated band brake would require manual intervention, B) a manual override switch may not be automatically activated in a power failure, and C) the weight of the load alone would not stop the movement of the winch.
