Which system provides directions to locate the exits and lights the escape path during an evacuation?

• A. Emergency Lighting System
• B. Flight Deck Intercommunication System
• C. Ground Power Unit
• D. Circuit Breaker

Answer: (A)

Emergency lighting provides directions to locate the exits and lights the escape path when power is lost during an evacuation. In an emergency, visibility can drop quickly, so exit signs and floor-level escape-path lighting stay illuminated and clearly indicate the fastest way out. This system is usually battery-backed and designed to automatically activate if the main power fails, ensuring exits are visible and the path is lit from the cabin to the doors.

The other systems have different roles: the flight deck intercommunication system is for crew communication, not guiding passengers; the ground power unit supplies external power to an aircraft on the ground; circuit breakers protect electrical circuits from overloads.
