Someone said that the latest generation of ETOPS Aircraft (A330 & B777) &
their engines (PW 4000, RR Trent, GE80) now fully comply with the safety
objectives of FAR 25.1309 (probability of double engine failure < 10 exp
-9 per flight hour), in areas of operation where the mean diversion time
remains less then 120 minutes (North Atlantic, Central Atlantic, Indian
Ocean, Central Pacific).
OK, but what about areas of operation where the mean diversion time is
longer, namely the North Pacific?
