Definition
Simplified visual depictions of an airport's runway and taxiway layout, printed on instrument approach procedure charts to help pilots identify the landing runway and plan the route from the runway to the ramp after landing.
Plain English
A small drawing of the airport, included on an approach chart, that shows the runways and taxiways so a pilot can find the right runway and figure out how to taxi in once they land.
Context Anchor
Seen in FAA instrument procedure materials, especially when a pilot is reviewing the airport layout before or after flying an instrument procedure.
Derivation
Airport combines “air” with “port,” meaning a place where aircraft arrive and depart. Sketch comes from an older word meaning a quick or rough drawing. In aviation, the term keeps that idea of a simplified drawing, but the sketch is still a standardized published aid, not a casual hand drawing.
Why Pilots Care
They allow pilots to quickly understand airport geometry during instrument approaches when visual references may be limited.
Intuition Check
Do not assume “sketch” means an unofficial or unreliable drawing. Here, an airport sketch is a published simplified layout, but it is still less detailed than a full airport diagram.
Example Sentence 1
Before starting the approach, the pilot reviewed the airport sketch to confirm which taxiway would lead from the runway to the FBO ramp.
Example Sentence 2
Airport sketches in the handbook include details like displaced thresholds that are critical for safe operations.
