Hi,
Has Qantas ever published figures wich 767 is cheaper to operate the GE or RR powered one?

Thanks
Andre

I believe I read somewhere the GE's burn less fuel during descent...

Well there has to be a reason why only two airlines brought only a handful of RR powered 767's

When BA bought the 767 in the late '80s they wanted to streamline maintenance.
747 and 757 as well as TriStars used all the RB211 engine. BA was the launch
customer for the RR powerd 767 ,if I remember correct. I have to chase this up
I still got some journals from that time.

As far as I am aware the GE powered 767 is the more fuel efficient of the two.

QF only purchased the ex-BA RR powered 767's as they were going for a steal at the time is what I have heard.

On a side note. In the flare, when closing the thrust levers, the Rb211's run down to idle very quickly. The CF6 is a bit slower being two shafted. So you have to treat them a bit differently just before touchdown.
