Let me guess, you fly for QF?
ETOPS/EDTO entry point. There's an EXP too.
For some operators - particularly in AU- , he EEP is wheels off. That is ETOPS rules apply from wheels off, even from somewhere like Paris across the Atlantic. If heading out over Brittany, if it goes cr@p downstream at all your EDTO alternates then it doesn't matter, captains call as you were in EDTO at liftoff.
For (all?) others the EEP is the point at which you get to (the predetermined distance that equates to) 60 mins from an adequate airport. If the weather goes to pot at all of your alternates as you are heading out over water, already some time into your flight, you don't enter EDTO airspace. (i.e. proceed beyond the 60 mins distance)
