Definition
A Terminal Area Chart is a large-scale VFR aeronautical chart, published at a 1:250,000 scale, that depicts the airspace surrounding selected major airports designated as Class B airspace. It shows greater detail than the surrounding Sectional Chart, including airspace boundaries, altitudes, terrain, obstructions, navigation aids, visual checkpoints, and airport information needed to navigate safely in and around busy terminal areas.
Plain English
A zoomed-in VFR map of the airspace around a major airport. It shows the same kind of information as a regular VFR chart, but with much more detail because the airspace around big airports is busy and complex.
Context Anchor
Pilots use TACs during VFR planning and navigation near major airports and busy terminal areas.
Derivation
"Terminal" comes from the Latin terminus, meaning "end" or "boundary" — in aviation it refers to the area at either end of a flight, where aircraft are arriving or departing an airport. "Area" indicates a defined region of airspace. So a Terminal Area Chart is a map of the airspace around a flight's start or end point.
Why Pilots Care
They supply the resolution needed to stay clear of obstacles, remain outside or inside specific airspace, and follow preferred routes in high-traffic terminal areas where sectional charts are too coarse.
Intuition Check
Terminal does not mean “final” or “ending” here. It means the airspace around a major airport where arriving and departing aircraft are concentrated.
Example Sentence 1
Before flying into the Class B airspace around Miami, the pilot reviewed the Terminal Area Chart to identify visual checkpoints and altitude limits.
Example Sentence 2
While flying the practice area, the student used the TAC to locate the nearby power lines that did not appear on the sectional.
