I was just checking out the Boeing orders and deliveries sheet for Cathay Pacific and I noticed they have an unfilled order for 6 744ERFs with PW power. Is this a typo? First of all, I was under the impression that all 744 ER variants are GE powered. Secondly, It appears when it comes to Boeing (and perhaps airbus for that matter, I don't really know) CX has always been a RR customer, except on GE exclusive aircraft. My guess is this is just an oversight on the part of some web designer. Any insights...?
No, it's not. The 747-400ERF is offered with PW4062s and CF6-80s. The only engine not offered for the ERF is the RB211.
As for CX's 744ERF engine choice, it comes down to the fact that RR engines aren't offered on the ERF. And since they already operate a handful of ex SQ aircraft, which have PW engines, for PAX and cargo, it probably made more sense to order their ERFs with PW4062 engines instead of introducing yet another new engine type.
