Here is a question;
For ETOPS, the system relies on having a diversion runway available within a certain time from anywhere on the planned route.
Lets say that a flight enroute diverts to an enroute aerodrome that everyone in the system at that time is relying on..........does everyone else turn back or re-route straight away because that diversion could (when it gets there) block the single runway they are relying on for ETOPS?
