What is the minimum duration of a Torch?

The correct answer indicates that the minimum duration of a torch is 30 minutes. In the context of safety equipment on aircraft, torches must provide sufficient illumination in emergency situations where power might fail or visibility is compromised. The specified duration ensures that crew members have enough time to navigate safely or assist passengers without being hindered by inadequate light.

A 30-minute duration is practical and aligns with regulations in the aviation industry, as it provides enough operational time while being manageable in size and weight for storage in emergency equipment kits. Ensuring that torches meet this minimum duration requirement helps enhance safety and preparedness on board.
