What action should an aircraft take when receiving a steady red light signal from the tower?

When an aircraft receives a steady red light signal from the control tower, the appropriate action to take is to continue circling. This signal indicates to the pilot that the airport is closed to landing due to traffic or other operational reasons. It is essentially a way for air traffic control to manage the flow of aircraft safely and efficiently.

In this situation, the pilot should maintain altitude and continue to fly in the traffic pattern or circumnavigate the airport until instructed by the control tower to take further actions, such as landing or entering a holding pattern. This ensures that the aircraft does not attempt an unsafe landing or interfere with other aircraft that may be landing or taking off.

Understanding the implications of the signal reinforces the importance of adhering to air traffic control communications, which play a crucial role in maintaining safety within busy airspace.
