Airbubba, thank you very much! A key phrase is 'demonstrate' [...] without service experience (for 'early ETOPS'). I guess that today there may be enough engine-hours with the 773-GE115 to satisfy even the 'conventional' rule AC 120-42A? I have not yet read everything in the link posted, but I assume that the AC 120-42A will 'take over' as soon as the service experience required has been met?
Thanks!
