Definition
To change a planned course of travel, instruction, or flight from its original path to a new one, typically in response to changing conditions, requirements, or student needs.
Plain English
To send something — a flight, a lesson, or a process — along a different path than originally planned.
Context Anchor
Seen in discussions of programmed training, computer-based lessons, and instructor decisions about what a learner should review next.
Derivation
From 're-' (again) plus 'route' (a way or path), originally from the Old French 'route' meaning a chosen course. Literally: to choose the path again.
Why Pilots Care
Reroutes directly affect fuel planning, arrival times, and compliance with airspace rules.
Intuition Check
Do not assume reroute only means changing an aircraft’s flight path. In this instructor-training context, it means changing the student’s path through the lesson or training material.
Example Sentence 1
ATC issued a reroute around the line of thunderstorms, and the pilot copied the new waypoints onto the flight log.
Example Sentence 2
We accepted the reroute south of the military operations area to keep the flight on schedule.
