Definition
Electronic cockpit displays that show the airplane's current position on a chart or airport diagram in real time, with the map updating continuously as the airplane moves. On the ground, a moving map display shows the airplane's location on the airport surface, including taxiways and runways, helping the pilot identify exactly where they are and confirm they are aligned with the correct runway before takeoff.
Plain English
A screen in the cockpit that shows a map with your airplane on it, and the map moves as you move so you can always see where you are.
Context Anchor
Pilots use moving map displays on panel equipment or tablets during navigation, approach, and landing to help confirm they are lined up with the intended airport, runway, or landing surface.
Derivation
“Moving map” comes from the idea that the map image updates as the airplane moves. The paper map is no longer fixed in the pilot’s hands; the display keeps changing to show the airplane’s present place on the map.
Why Pilots Care
They improve situational awareness and reduce the chance of landing on the wrong runway or surface by making the aircraft's position immediately visible.
Analogy
Like the GPS map on a phone that shows a little arrow representing the car and updates as the car drives — except here it shows the airplane on a runway and taxiway diagram.
Intuition Check
The map itself is not physically moving. The display is updating the airplane’s position on the map as the airplane moves.
Example Sentence 1
Before crossing the hold short line, the pilot glanced at the moving map display to confirm they were entering Runway 27, not the parallel taxiway.
Example Sentence 2
Before descending, the instructor had the student use the moving map display to identify the right airport surface.
