Definition
Printed or electronic maps designed specifically for aviation use, depicting information pilots need to plan and conduct flight, including airports, navigation aids, airways, airspace boundaries, terrain, obstacles, and communication frequencies.
Plain English
Special maps made for pilots. They show what matters in the air: airports, airspace, terrain, towers, radio frequencies, and the routes used for navigation.
Context Anchor
Seen when comparing the information shown on published aviation charts with the information stored in an aircraft navigation database or displayed by a panel navigation system.
Derivation
‘Aeronautical’ comes from the Greek ‘aer’ (air) and ‘nautikos’ (relating to sailing or navigation) — literally ‘air navigation.’ A chart, in the navigational sense, is a map made for travel rather than general reference, a term carried over from marine use.
Why Pilots Care
These charts supply the legally required information for route selection, altitude compliance, and hazard avoidance, directly supporting regulatory adherence and flight safety.
Intuition Check
Do not read charts here as graphs or simple illustrations. In aviation, charts are official flight maps containing information a pilot may use for real navigation and decision-making.
Example Sentence 1
Before departure, the pilot reviewed the aeronautical flight charts to identify restricted airspace along the route.
Example Sentence 2
While airborne, the crew cross-checked the approach plate against the current aeronautical flight charts to verify any updates to the missed approach procedure.
