BA 772
hey there
as we know that british airways powers its boeing 772 with either rr trent800 or ge90 engines , but i noticed that it serves LHR -singapore - sydney route with its 772 with rr trent800 , in other words never uses 772 with ge90 in this sector , the link below supports what i said , i'd like to know why is that , is it for technical reasons related with engines or what ?? is rr trent800 is more efficient than ge90 for long haul flights or it burns less fuel ???

dear wiggy
as you said that (BA's GE engined 777-200s don't have any onboard crew rest facilities installed so you'd run into problems with crew duty times on the LHR-SIN and SYD-LHR sectors).
that's a v.good answer , but it seems to me that ge90 & pw4000 engines have the ability to fly for long haul flights , for example : austrian airlines was using ge90 engines on its 772 on Vienna - Kula lumpur - sydney sector , as well as air austral uses its 772 with pw4000 engines in reunion - Sydney route
So do you mean that only BA 772 with ge90 engines is certified for a lower takeoff weight & the payload would restricted on the longer sectors or its for any 772 powered with ge90 ???

Hi adarob, I was specifically talking about BA's GE engined 200's, and even within that fleet there variances in the certified weights, dependant on wether it's an A market aircraft or an ER but they are always lower Max Take Off weights than the Trent engined -200ERs.
I don't have any information on what limits/weights the other operators you mention are using - maybe one of their Flightcrew will spot this thread and be able to help out.
