For how many minutes are emergency lights operational on the CRJ 200?

The correct answer is that emergency lights on the CRJ 200 are operational for 15 minutes. Emergency lights are crucial for ensuring visibility in the cabin and helping passengers evacuate safely in the event of an emergency. The duration of operation is designed to provide sufficient time for a safe evacuation following a power loss or other emergency situations. Knowing that the emergency lights last for 15 minutes is imperative for crew preparedness and passenger safety, allowing them to guide evacuees in low-light conditions until they can reach an exit or the situation is resolved. This duration is standardized across many aircraft to ensure equipped lighting is available during critical moments.
