The taxi/recognition light will come on, regardless of its switch position, if which condition occurs?

• A. The captain issues a switch override.
• B. The landing gear is extended.
• C. The respective wing landing light is turned on.
• D. The nosewheel misaligned.

Answer: (C)

Lighting circuits on aircraft are often wired with interlocks so that essential visibility is maintained without relying on every switch being in the right position. In this case, the taxi/recognition light is connected so that when the wing landing light is turned on, power flows to the taxi/recognition light as well. This ensures the aircraft remains conspicuous on the ground whenever wing lights are active, even if the taxi/recognition light switch is off or in another setting. The other conditions—an override command, the landing gear being extended, or a misaligned nosewheel—don’t provide the electrical path to energize the taxi/recognition light, so they wouldn’t cause it to illuminate automatically.
