FAA Ground School Practice Test

What does a flashing white light signal indicate when given to a taxiing aircraft?

1. Proceed with takeoff

2. Return to the starting point on the airport

3. Give way to traffic

4. Hold position

The correct answer is: Return to the starting point on the airport

A flashing white light signal directed toward a taxiing aircraft conveys the instruction to return to the starting point at the airport. This signal is typically utilized in scenarios where the aircraft has taxied beyond its intended location or is heading toward a restricted area. It helps ensure the safety and orderly movement of aircraft on the ground by providing clear guidance for the pilot to follow. In contrast, the other signals associated with ground operations have distinct meanings. For instance, a steady green light indicates that an aircraft is cleared for takeoff, while a flashing yellow light requires the aircraft to give way to other traffic. A steady red light or flashing red light signal commands the aircraft to hold its position, which is not synonymous with the instruction given by a flashing white light. Thus, the flashing white light serves as a specific directive for aircraft to return to their point of origin, ensuring overall situational awareness and safety.
