Which door component functions as a light?

• A. Slight Light
• B. Arming Lever
• C. Emergency Placard
• D. Girt bar Indicators

Answer: (A)

The idea being tested is that some door components are designed to provide illumination to guide people during use or evacuation. The light at the door sill is there to illuminate the floor right at the exit, making it easier for passengers to see where to step and to locate the handle or latch in dim conditions. This lighting can be powered by the aircraft’s electrical system or by emergency power and may come on when the door is opened or in an emergency. The other items don’t serve as lights: the arming lever is the mechanism used to arm or disarm the door for emergency egress; the emergency placard provides written instructions; and the girt bar indicators show whether the girt bars are properly latched. So, the door sill light is the component whose function is to light the area around the exit.
