What action should an aircraft in flight take when receiving a steady red signal?

When an aircraft in flight receives a steady red signal, the correct action is to give way to other aircraft and continue circling. This signal indicates to the pilot that the aircraft should not attempt to land but instead yield to any other aircraft in the vicinity, ensuring safety in the airspace by allowing for proper traffic management.

The signal's purpose is to prevent collisions and maintain orderly operations. While circling, the pilot can safely assess the situation, maintain control of the aircraft, and wait for further instructions from air traffic control. This method helps manage any potential conflicts with other air traffic that may be approaching the runway or airspace.

Other options might suggest actions that could disrupt the flow of traffic or lead to unsafe situations. For instance, landing immediately could put the aircraft in conflict with other traffic or create an unsafe landing scenario. Climbing to a higher altitude might not resolve the situation effectively, as the pilot could still encounter obstacles or other aircraft overhead. Returning to the departure airport might not be feasible based on air traffic conditions and could complicate the current situation further. Therefore, the most prudent action in response to a steady red signal is to give way to other aircraft and continue to maintain a safe circling maneuver.
