What does flashing white signal indicate?

• A. Steady green = proceed
• B. Steady red = stop
• C. Flashing white = return to start
• D. Flashing red = clear runway

Answer: (C)

Flashing white on the airport surface signals is a specific ground signal telling the pilot to return to the starting point on the movement area. It’s used to reset your position or to backtrack to where you began before continuing taxiing or coordinating with ATC. This makes sense because, in busy airfields, players need a clear way to reposition without making abrupt or unsafe movements, and returning to the start is the safest, most straightforward instruction.

Steady green and steady red convey different clearances or restrictions depending on context (in the air vs. on the ground), and flashing red indicates an unsafe condition or to stop and clear the runway in most scenarios. Those do not describe returning to the initial point, which is why flashing white is the best match for returning to start.
