Diversion airport

Diversion airports are airports capable of handling a particular ETOPS rated aircraft during an emergency landing and whose flying distance at the point of emergency shall not exceed the ETOPS diversion period for that aircraft.

Any airport designated as an en route diversion airport must have the facilities to safely support that particular aircraft, and weather conditions at the time of arrival must allow a safe landing with an engine and/or systems malfunctioning.[1]

An ETOPS/LROPS flight may be conducted solely if the diversion airports are available throughout the length of the flight. Unavailability due to bad weather, for example, might require an inflight rerouting.
