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

Thanks

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.

Martin, is that why the RR powered a/c hit the deck like a rock?

On that note what is the difference (apart from being single shafted) and benefit of a single shaft RB211 vs the twin shaft CF6?

Nick,

I believe the QF 767's were leased from BA, not purchased.

I am not sure that BA really want them back!

As to handling in the flare... maybe thats my problem! I've never had the brainspace to do anything other than just close them!

Owen,
The ZX series were leased originally from BA for a number of years, and then at the end of the lease Qantas purchased them I am lead to believe.

Nick,

I think you'll find the RB211 has three shafts.
