I Have charts coming out of my ears !
SO Thanks very much but I will politely decline
The problem is "our" Adv variants have the later -15 Engines so of course the PCDS Needs to take this into account ..
Do we cruise the Same Mach but with a lower EPR ?
OR Do we cruise at a Higher Mach with the Same EPR ?
(when compared to the earlier -200 engines)
