I have not found a similar list of systems in any of our Boeing manuals.
For example, a generator failure in flight does not require you to land at the nearest suitable airport. You can continue trucking along the country for the entire flight.
However, you cannot be dispatched with this same failure on an ETOPS flight. Its a pretty obvious example and I think we all know what to do in this particular circumstance.
But, for lesser systems that are not so obvious, does Boeing provide guidance as to whether proceeding into an ETOPS area should or should not occur?
Cheers in advance
Probably varies a little by type, however our company manuals state:
“any critical system failure precludes ETOPS operations and requires a diversion if within the ETOPS segment.
Critical system failure is:
- an engine failure
- only two AC power sources remaining
- hydraulic system failure that seriously restricts the operation of the aircraft.”
This has basically been the same across all twin jets I’ve flown with ETOPS capability.
Hope this helps!
