RR in trouble? Hardly
Gulfstream make bizjets, I think. All the large cabin aircraft have RR engines. So, RR alive and kicking there.
As for the 535, I seem to remember airlines switching to it having initially chosen Pratts.
As for the B777, that was a blow, but then along came the A350 and the boot was on the other foot, in my view.
And RR has been gaining market share steadily on the A330. I'd be really interested if anyone could lend weight to the claims that the Trent 700 has some shortcomings.
Probably all some dreadful misunderstanding on my part. That the crew did their jobs well the other day is the one thing that is clear.
