Story Behind BA 777 Engines

Mon Nov 19, 2001 7:45 pm

Why did they order the GE90? They are a huge RR costumer. Then why did they switch to RR?

First part:

1) BA had a maintenance operation in Cardiff.

2) BA sold it to General Electric.

3) BA orders General Electric engines.

Items 2) and 3) being purely coincidental  Wink/being sarcastic

Second part:

Don't know why but perhaps the RR engines are more powerful?

BA switched from a British manufacturer to an American one because of Margaret Thatcher? Er... I don't quite follow.

Yes, David, because as we all know, Thatcher is anti-british... NOT! Afaik, BA switched from GE to RR, or am I wrong (again) ???

As near as anyone can tell, BA had horrendous teething problems with the GE90s and promptly switched to the Trents when they had the chance. Both engines are equally powerful.

I guess it all comes down to price. It was reported at the time that the RR engine deal was one of the most hotly contested engined deals ever. BA probably just accepted the bid that made the most financial sense.

Enginesrus is correct, and the GE90 buy was not a popular move anyway.
I've heard tales of dodgy dealings with the GE90 deal in 1991, but I'm not going to repeat them as I've no way of knowing if they were true.

The RR Trent engine is based on the dependable RB211 engine. The GE90 is a wholly new engine with better specific fuel consumption.

This explains the teething problem with the GE90.

BA is private company and such considerations as engine choices should be made by management without government intervention.

Another reason for the switch to RR was the decision to cancel/convert some 747-400 orders. The 747's would have been RR powered. Since BA had the engines on order as well and I believe had already partially paid for them, it made sense to simply convert the order to engines for the newer 777's.

Simply put, the GE90 is one bad-ass engine!

Dash 80, I am afraid your statement is baseless. Lately, the three B777 engines have very similar IFSD rates. All three are well below the 0.02 per 1000 EFH rate that is required for 180 ETOPS rating. I believe the GE90 is actually in the middle of the pack, in terms of IFSD rate, but I have to check.

BA'S RR 777 engines are rated at 95000lbs of thrust each whereas the GE -90s are a mere 90000lbs.

A quick look at Bill Harms' website revealed 29 777s with GE engines, while another 16 are equipped with RR engines. Anyone know if BA has more 777 on order, with either powerplant? Regards.

Nope, that's all BA has ordered (45). It probably will have to wait a year or two before BA is financially sound enough to make additional orders.

What do you think will happen to those GE-powered 777s when it comes to D-checks? Afaik, engines are removed for D-check. So will they put RR-engines even on the now GE-powered 777s after D-check?

The reason I said the GE90 is bad-ass is because it's the most powerful jet engine out there with the GE90-115B rated @ 115,000 lb-thrust. You don't have to break it down or nothing, I am just making an observation.
