Definition
Navigation is the process of determining an aircraft's position and guiding it from one geographic point to another along an intended route, using visual references, charts, instruments, radio aids, or satellite-based systems.
Plain English
Knowing where you are, where you're going, and how to get there.
Context Anchor
Seen on cockpit displays, avionics buttons or pages labeled NAV, flight planning materials, charts, and handbook discussions about finding and following a route.
Derivation
From the Latin navigatio, from navis (ship) and agere (to drive or lead). Originally about steering ships; the same idea was carried over to aircraft — leading the craft to its destination.
Why Pilots Care
Accurate navigation prevents airspace violations, fuel exhaustion, and controlled flight into terrain.
Grounding Statement
Navigation answers three practical questions: Where am I, where am I going, and how do I get there safely?
Intuition Check
Navigation does not just mean “traveling.” In aviation, it means actively knowing and managing the aircraft’s position and path.
Example Sentence 1
The pilot selected NAV mode on the autopilot to follow the programmed route.
Example Sentence 2
During the cross-country flight, dead reckoning navigation served as backup when the GPS failed.
