Thanks guys, getting there,
I've read elswere the major benifit of the rb-211 was it's reliability, anyone else with experience heard this? I realise the RR is by far the most expensive, what would be the benifit of an operator choosing this type of eng? I've heard rumblings about the length of the engine (RR being shorter) and therefore increasing efficiency? Or is this Nonsense?
Thanks for the continued help!
