Definition
National Aeronautical Navigation Products (AeroNav Products) is the FAA office responsible for designing, producing, and distributing official U.S. civil aeronautical charts and flight information publications, including sectional charts, terminal area charts, IFR enroute charts, and instrument approach procedure charts.
Plain English
It is the part of the FAA that makes and publishes the official aviation charts and flight information booklets that pilots use for navigation.
Context Anchor
Seen when gathering flight planning information, especially before an instrument flight or when checking current charts, airport details, and published procedures.
Derivation
Aeronautical' comes from the Greek 'aer' (air) and 'nautikos' (relating to ships or sailing) — literally 'sailing through the air.' 'Navigation Products' simply means the maps and publications used to find your way. So the office name plainly states what it does: it produces the nation's air-navigation charts.
Why Pilots Care
These products supply the accurate, current navigation data required for legal and safe instrument flight planning and operations.
Intuition Check
Do not read “products” here as optional merchandise or pilot supplies. In this FAA context, it means official flight charts and publications that pilots rely on for planning and navigation.
Example Sentence 1

Example Sentence 2
