The correct answer is: Stop

A steady red light gun signal directed at an aircraft on the ground signifies "Stop." This signal is used by air traffic control to indicate that the aircraft must immediately halt its current actions, whether it is taxiing, preparing for takeoff, or any other movements. This is crucial for maintaining safety on the airport ramp and runway, as it can prevent collisions or other hazardous situations. Understanding this signal is vital for pilots, as it helps them respond appropriately to air traffic control commands, ensuring that they operate safely within the airspace system. The steady red light is universally recognized in aviation as a signal to stop, reinforcing the importance of adherence to air traffic instructions to avoid potential accidents.
