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?

  1. AThat the taxiway is closed.
  2. BA temporary holding position for intersecting runways.
  3. CThat the runway is permanently closed.
  4. DA runway intersection where special procedures apply.
Show answer & 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.
