Which component is used to activate the Emergency Lights System?

• A. Flight Attendant Control Panel
• B. Emergency Exit Sign
• C. Passenger Service Unit
• D. Oxygen Mask Panel

Answer: (A)

The ability to switch on the cabin’s emergency lighting is located on the Flight Attendant Control Panel. This panel houses the Emergency Lights controls, so the crew can manually activate the system to illuminate the cabin, aisle path lighting, and exit signs during an evacuation or power loss. The Emergency Exit Sign is simply an indicator that lights when the ELS is active or power is available; it doesn’t start the system by itself. The Passenger Service Unit provides passenger lighting and call functions, but it does not control the emergency lighting. The Oxygen Mask Panel relates to oxygen deployment, not lighting. In an emergency, activating the ELS from the Flight Attendant Control Panel ensures a clear, illuminated evacuation path for passengers, with automatic backup power taking over if main power fails.
