What action should be taken when encountering an area marked with a painted X?

An area that is marked with a painted X is typically a signal that the runway or taxiway is closed and should not be used for any aircraft operations. Encountering this marking indicates that the area is unsafe for landing, takeoff, or taxiing, and thus requires pilots and ground personnel to avoid it entirely.

The painted X serves as a visual warning to prevent accidents and ensure safety on the airfield. It communicates that the area may be under maintenance, obstructed, or otherwise compromised. Therefore, the most appropriate action when you see this marking is to avoid the area completely to ensure the safety of all operational activities within the airport environment.

In contrast, other actions, such as landing, proceeding to taxi through, or contacting ground control for clearance, may place personnel and equipment at undue risk and do not align with safety protocols regarding the painted X marking.
