B744 Facts

Thu Dec 06, 2001 2:07 pm

My own perceptions about the B744 models with different engines are as follows:

1) RR RB211-524G/H-T (most powerful engine)
2) GE CF6-80C2B1F (middle)
3) PW 4056 (least powerful engine)

1) PW 4056 (longest range)
2) GE CF6-80C2B1F (middle)
3) RR RB211-524G/H-T (shortest range)

Also, to the best of my knowledge, GE CF6-80C2B5F (which is rated at a more powerful 61,500 lbs. thrust) has only been used by 2 airlines on B744: Saudi Arabian Airlines & Virgin Atlantic but PW 4062 (which is rated at the most powerful at 62,000 lbs. thrust) has never been used by any airline for B744 so far.

Can you please correct me if I'm wrong with the facts shown above? Otherwise I may assume that my information is accurate. Thank you very much!

I think that United uses the PW also.
That'll happen!

United uses the PW4056, not the PW4062
