Definition
The standardized practices a pilot follows when moving an aircraft on the ground between parking, runways, and other movement areas, including pre-taxi planning, use of an airport diagram, proper speed control, compliance with ATC instructions and airport markings/signs, and continuous positional awareness to prevent runway incursions.
Plain English
The set of habits and steps a pilot uses to safely drive the airplane around the airport on the ground without getting lost, going too fast, or accidentally entering a runway.
Context Anchor
You meet this term during pre-takeoff taxi, after-landing taxi, and runway incursion avoidance training.
Derivation
In aviation, “taxi” came to mean moving an aircraft on the ground under its own power, much like a taxicab moves along streets before reaching its destination. That helps separate it from flying: taxiing is ground movement, not flight.
Why Pilots Care
Proper execution prevents runway incursions, which remain a leading cause of ground accidents and near-misses at busy airports.
Intuition Check
Do not read “taxi” here as a car-for-hire meaning. In this context, it means moving an aircraft on the airport surface under control, usually using its own power.
Example Sentence 1
Before requesting taxi clearance, the pilot reviewed the airport diagram and briefed the route as part of standard taxi operating procedures.
Example Sentence 2
Reviewing the airport diagram before engine start helps a pilot anticipate the taxi operating procedures required at an unfamiliar field.
