How long does the Emergency Lighting System last at a minimum once activated?

The Emergency Lighting System is a critical safety feature that activates during emergencies to illuminate exit paths and ensure passengers can evacuate safely. When activated, this system is designed to last for a minimum of 10 minutes. This duration is crucial as it allows enough time for crew members to direct passengers to exits and for individuals to leave the aircraft safely, especially in low-visibility situations. The system’s design focuses on providing sufficient illumination during the initial moments of an emergency when time is of the essence. The choice of 10 minutes reflects industry standards aimed at ensuring passenger safety during emergencies.
