Definition
In FAA training and testing standards, the specific aeronautical charts that match the type of flight being conducted — for example, current VFR sectional charts for visual flight, terminal area charts near busy airspace, and IFR low or high altitude en route charts for instrument flight. A chart is 'appropriate' when it is the correct type for the operation, covers the area of flight, and is current.
Plain English
The right charts for the job — the ones that cover where you're flying, match the kind of flying you're doing, and are still in date.
Context Anchor
Seen in flight training, lesson planning, preflight planning, and instructor directions about what materials a student must have available.
Derivation
Appropriate' comes from the Latin appropriatus, meaning 'made one's own' or 'suited to.' In aviation, it carries the sense of 'fitted to the purpose' — not just any chart, but the one that fits this flight.
Why Pilots Care
Selecting the correct charts prevents navigation errors, airspace violations, and loss of situational awareness.
Intuition Check
Appropriate does not mean any chart that looks useful. It means the chart must fit this exact flight or lesson and be current enough to rely on.
Example Sentence 1
The student arrived at the checkride with appropriate charts for the planned cross-country, including a current sectional and the terminal area chart for the destination.
Example Sentence 2
In low visibility, pilots must keep the appropriate charts open and ready for the planned approach.
