Definition
A VFR aeronautical chart published by the FAA at a scale of 1:500,000, showing topographical features, airspace boundaries, airports, navigation aids, obstructions, and other information needed for visual flight. Each chart covers a specific region of the United States and is named for a major city within that region.
Plain English
A detailed map made for pilots flying by visual reference. It shows the ground below, the airspace above, airports, towers, and other things a pilot needs to see and avoid while navigating.
Context Anchor
In the Airplane Flying Handbook, a pilot may use a sectional chart before practicing eights on pylons to choose suitable ground points and understand the surrounding area.
Derivation
Sectional comes from section, meaning a part of a larger whole. Each chart covers one section of the country, and together the full set covers the entire United States.
Why Pilots Care
Sectional charts provide the essential visual and airspace information pilots need to navigate safely, avoid obstacles, and comply with regulations when flying under visual flight rules.
Analogy
A sectional chart is like a road map for pilots, but instead of showing only roads and towns, it shows the features that matter from the air.
Intuition Check
“Sectional” does not mean a chart for one maneuver or one slice of your route. It means the chart covers one geographic section of a larger map system.
Example Sentence 1
Before the cross-country flight, the student folded the sectional chart so the planned route was visible at a glance.
Example Sentence 2
During the eights-on-pylons maneuver the instructor used the sectional chart to identify suitable ground references visible from the cockpit.
