You receive a flashing white light from the control tower during run-up prior to takeoff; what action should you take?

The flashing white light signal from the control tower during a run-up prior to takeoff indicates a need for the aircraft to return to the starting point at the airport. This light signal is a method of communication used by air traffic control to convey instructions to pilots, and it specifically relates to ground operations. When a pilot receives this signal, it is crucial to comply and safely maneuver the aircraft back to its original location, usually the ramp or parking area.

By following this instruction, the pilot helps ensure safety and coordinated traffic flow at the airport. The importance of this procedure stems from the need to avoid any potential conflicts with other aircraft operations or ground activities that may require the taxiway or runway to be clear. Thus, the response accurately reflects adherence to air traffic control communications and safety protocols.
