Regarding the Etops question, I was under the impression that Etops was not simply a Manufacturer/ Airframe concern,but the Individual Operator had to demonstrate a satisfactory period of operating a particular Engine/ Airframe combination.
I recall when QF first started operating the A330 it was not Etops approved until those parameters had been satisfied...accordingly the A330 remained a domestic vehicle for a considerable period prior to being utilised Internationally. This despite the fact that the Engines on the A330 were Identical with those on the 767 which was happily plying the skies with 180 min Etops approval .
One can but wonder how this affects Jet* operation of the Dreamliner in these circumstances .
