In the event of a power failure, which lights are expected to operate from battery power?

• A. Cabin lights and exit signs
• B. Overhead emergency lights and exterior lights
• C. Overhead emergency lights, aisle escape lights, and EXT lights
• D. Flight deck lights and cargo lights

Answer: (C)

In the event of a power failure on the A320, overhead emergency lights, aisle escape lights, and exterior lights (EXT lights) are designed to operate from battery power. This capability ensures that critical lighting remains functional during an emergency, allowing for safe evacuation and navigation in dark or smoke-filled environments. Overhead emergency lights provide essential illumination in the passenger cabin, guiding passengers and crew toward exits. Aisle escape lights enhance visibility along the aisles, helping occupants find their way to emergency exits quickly. Exterior lights ensure visibility of the aircraft for emergency responders and enhance safety during an evacuation. The provision of battery power for these specific lighting systems is crucial in maintaining safety and operational integrity when the main power source is lost.
