Definition
The process of planning, recording, and controlling the movement of an aircraft from one place to another, using visual references, instruments, radio aids, or satellite-based systems to determine and maintain a desired course.
Plain English
Figuring out where you are in the air, where you're going, and how to get there safely.
Context Anchor
In this chapter, the term appears in the legal and safety context of the Federal Aviation Act of 1958, which helped define federal responsibility for safe flight in U.S. airspace.
Derivation
From Latin 'navigatio,' meaning 'a sailing' or 'voyage,' originally tied to ships. As aviation developed, the same word was carried over to describe guiding aircraft through the sky. 'Air navigation' simply specifies that the navigating happens in the air rather than on water.
Why Pilots Care
Air navigation is the core skill of getting from A to B without getting lost, busting airspace, or running out of fuel. Every flight involves it, whether you're using a paper chart, a GPS, or following a controller's vectors.
Intuition Check
Air navigation is not just reading a map. It means actively knowing and managing the aircraft’s position, direction, and route during flight.
Example Sentence 1
The Federal Aviation Act of 1958 gave the FAA authority over air navigation facilities such as radio aids and control towers.
Example Sentence 2
Good air navigation keeps the aircraft inside assigned airspace and on schedule for arrival.
