Which of the following is NOT a designated lighting setup for taxiing?

The correct response indicates that "Crossing lights OFF" is not a designated lighting setup for taxiing. During taxi operations, specific lighting configurations are essential for safety and visibility. The beacon provides a warning signal that helps alert others on the ground to the aircraft's presence, while the position lights ensure the aircraft's location and orientation are visible to other aircraft and ground personnel. Having all lights on may serve to increase visibility, but typically, specific lighting requirements are outlined for different phases of flight.

In this context, the crossing lights are generally associated with runway wait or crossing procedures, often used to signal that the aircraft is crossing active runways. Keeping these lights off during taxiing is more aligned with standard operating procedures to prevent confusion on the taxiway, where other aircraft and ground vehicles may be present. This differentiation underscores the importance of using designated lighting setups appropriately for different situations on the airfield.
