Definition
The act of changing course in flight to land at an airport other than the originally intended destination, typically due to weather, fuel concerns, mechanical issues, medical emergencies, or other operational factors that make continuing to the planned destination unsafe or impractical.
Plain English
Choosing to land somewhere other than where you originally planned to go, because something has changed and continuing to the original airport is no longer the right choice.
Context Anchor
Seen when using avionics, such as a primary flight display, to find and navigate to a nearby suitable airport during a change of plan.
Derivation
From Latin 'divertere', meaning 'to turn aside' (di- 'apart' + vertere 'to turn'). The aviation meaning keeps this sense exactly: turning aside from the planned route to a different destination.
Why Pilots Care
Enables a safe response to unexpected problems by directing the aircraft to a closer or more suitable airport instead of pressing on.
Intuition Check
Diverting does not mean wandering off course by accident. In aviation, it means making a deliberate change to a different safe plan.
Example Sentence 1
With thunderstorms blocking the route to the original destination, the pilot began diverting to a nearby airport with clear weather.
Example Sentence 2
The crew used the nearest-airport feature to locate a better option and initiated diverting procedures before fuel became critical.
