Definition
A flight training task in which a pilot, while en route to a planned destination, is required to change course and navigate to a different airport or waypoint, demonstrating the ability to estimate heading, distance, fuel, and time to the new destination using available tools and resources.
Plain English
A practice scenario where the instructor tells the pilot to stop flying to the original destination and head to a different airport instead, so the pilot has to work out a new heading, distance, time, and fuel burn on the spot.
Context Anchor
Seen in flight reviews, training flights, and practical evaluations when an instructor wants to see how the pilot handles an unplanned change of destination.
Derivation
From the Latin 'divertere,' meaning 'to turn aside' or 'to go a different way.' In aviation, a diversion is literally turning aside from the planned route, and an exercise is a practice activity to build that skill.
Why Pilots Care
Practicing diversions builds the ability to handle unexpected situations such as weather changes or mechanical issues without becoming disoriented or unsafe.
Intuition Check
Diversion does not mean a distraction here. In aviation, it means deliberately changing from the planned route or destination to a safer or more suitable one.
Example Sentence 1
During the flight review, the instructor simulated deteriorating weather ahead and asked the pilot to perform a diversion exercise to the nearest suitable airport.
Example Sentence 2
The pilot completed the diversion exercise by identifying the alternate on the sectional, calculating fuel, and making the required radio calls.
