How long does the Emergency Light System last?

The Emergency Light System is designed to provide necessary illumination in the event of a power failure or other emergency situations, allowing passengers and crew to evacuate the aircraft safely. The system is engineered to last for a specific duration, ensuring that it fulfills its purpose effectively during critical moments.

The correct duration for the Emergency Light System is 10 minutes. This time frame is carefully chosen based on the average time needed for passengers to evacuate the aircraft and the availability of additional emergency lighting or exit pathways. While other options suggest longer or shorter durations, the standardization of 10 minutes reflects the balance between operational effectiveness and practical use in emergencies, aligning with safety regulations and best practices in aviation.
