What is the purpose of Floor Proximity Lighting?

• A. To guide flight crew to the cockpit
• B. To illuminate the exits in darkness
• C. To illuminate the galley
• D. To mark row numbers

Answer: (B)

Floor proximity lighting is part of the aircraft’s emergency lighting system and provides a low-level glow along the cabin floor to guide people toward the exits when visibility is poor or during an evacuation. This lighting helps passengers quickly and safely find the nearest exit routes, even in darkness or smoke. It’s positioned to outline the path to doors and exit rows, rather than lighting up areas like the galley or cockpit or simply marking row numbers. In short, its purpose is to illuminate the exits and escape routes in darkness.
