I would like to know if some of you knowledgeble folks out there could give me some answers to a few questions I've got.
I would like to know the take-off performance differences between two versions of 777-200ER at MTOW for a 5950nm mission. (Basically the runway requirements) The comparison is between a GE90 Powered 777-200ER at 656,000lb TOW vs PW4090 Powered 777-200ER at 632,500lb TOW. The assumptions are that both are carrying a full pax load of 234 persons and cargo is at maximum limited by fuel required for the mission. Also assuming same wind conditions for both aircraft.
Another question I would like to pose is does Boeing offer PW powered 777-200ER at 656,000lb MTOW, and if they do what is the engine thrust for that version. The information I have received says that 656,000lb MTOW is offered for R-R and GE powered 772ER but not PW.
If there is any other important parameter I left out of my inquiry I am sure someone will fill me in and I will rectify it if I can.
If you know what's really going on then you'll know what to do
