Definition#
A diversion (or alternate landing) occurs when a flight lands at an airport other than its intended destination. Causes include weather below minimums, mechanical problems, fuel emergency, passenger medical events, or security threats.
Why It Matters Operationally#
Diversions are costly — they require ground handling, passenger accommodation, repositioning, and crew duty-time management. Flight planning must always include sufficient fuel for diversion to a designated alternate airport.
