Can anyone tell me why Balair's new 757's are RR powered? I thought Swissair and SAir in general were very big on P&W engines because they own some kind of PW overhaul facility or something (SRTechnics). All of the 332 and MD11's have PW 4000 series engines. I know the PW 2000 are used for 757's but surely there must be some commonality between the two.
Didn't SR demand that Sabena change the engines of its new 332 to PW 4000 series from the GE CF6 because of this?
Now I see that the new Balair 763's will have GE CF6 engines, neither Pratt or RR powered.
Can anyone explain? Is it that the RR is the better/more efficient engine for the 757 and the CF6 better for the 767? Surely this cannot be so. I know that most 757 operators chose the RR over the PW engine but still.....
