Thanks for the info...
It will be rather embarrassing if, at just the time you need to get all the fuel out of a tank following a shutdown, an appreciable amount is "unusable" (assuming all the appropriate pumps were working correctly).
With regard to ETOPS, Maintrol used to class an ETOPS shutdown as one that occurred in an ETOPS segment of the flight, obviously things have changed.
However, I seems rather strange that an airline which wants to keep ETOPS "problems" to a minimum (in shutdown per sector figures) should include in the figures Non-ETOPS (non-twin) aircraft operating on Non-ETOPS flights!! After all there is twice the chance of a 747-400 suffering an IFSD compared to the (same engine equipped) 767!
