-
Emergency landing: Immediate landing due to imminent risk
-
Diversions typically involve controlled, non-critical situations
When each scenario applies
The scenario depends on the nature of the issue.
-
Technical degradation → diversion
-
Fire, smoke, loss of control → emergency landing
-
Medical emergencies may fall into either category
Passenger expectations in each case
Passenger experience varies by scenario.
-
Diversion: Unscheduled landing with controlled procedures
-
Emergency landing: Possible evacuation or rapid response
-
Both prioritize safety over comfort or schedule
