FAA Private Pilot Airplane (PAR)Airspace and AirportsEasy
A pilot is taxiing at an airport and observes a runway marking consisting of a yellow 'X' on the runway surface. What does this marking indicate?

- BA runway that is permanently closed to all aircraft.
- CA runway that is temporarily closed or unusable.
- DA designated helicopter landing area.
Show answer & explanationAnswer & explanation
Correct answer: C. A runway that is temporarily closed or unusable.
A large yellow 'X' placed on a runway indicates that the runway is closed to all traffic or unusable. If the runway is permanently closed, the marking may be more extensive, including a yellow 'X' at each end and sometimes at 1,000-foot intervals along its length.
Why the other options are wrong
- A. Runway intersections do not have 'X' markings; they are continuous lines.
- B. While a yellow 'X' can be part of a permanently closed runway marking, a single 'X' typically indicates temporary closure.
- D. Helicopter landing areas are typically marked with an 'H' or a circle, not an 'X'.
Closed Runway Marking (Temporary)
A large yellow 'X' placed on a runway indicates that the runway is temporarily closed or unusable for all aircraft operations. For permanent closures, 'X's may be more numerous and extensive.
- Marking: Large yellow 'X' on runway surface.
- Meaning: Runway is closed or unusable.
- Often indicates temporary closure.
Memory trick: Runway signs and lines tell you where to go and not to go.
