FAA Private Pilot Airplane (PAR)Airspace and AirportsEasy
A pilot is taxiing on an airport with an operating control tower and observes a large white 'X' painted on a runway intersection. What does this marking indicate?
- AThat the taxiway is closed.
- BA temporary holding position for intersecting runways.
- CThat the runway is permanently closed.
- DA runway intersection where special procedures apply.
Show answer & explanationAnswer & explanation
Correct answer: C. That the runway is permanently closed.
A large white 'X' painted on a runway or portion of a runway indicates that it is permanently closed to all aircraft operations. Pilots should not enter or use a runway marked in this manner.
Why the other options are wrong
- A. A closed taxiway is usually marked with a single 'X' or 'X's at intervals along its length, but a large white 'X' on a runway specifically means a closed runway.
- B. Temporary holding positions are typically marked with dashed lines, not a large 'X'.
- D. Special procedures at intersections are usually indicated by signs or specific ATC instructions, not a large white 'X'.
Permanently Closed Runway Marking
A large white 'X' painted on a runway or portion of a runway indicates that it is permanently closed to all aircraft for landing, takeoff, and taxiing.
- Indicates permanent closure.
- Applies to the entire runway or marked portion.
- Aircraft are prohibited from using or entering a closed runway.
Memory trick: An 'X' marks the spot where planes don't go.
