I would like Alex T to comment here please. I have watched a few videos of the 767 on line with PW engines and I have noticed that at CRZ (FL360 @ M.80) that the N1 readings are 88%. On a second video I watched, also PW engines, the N1 was 86%. Now I know this depends on weight etc, but the CS 767 always displays a value of 79 - 80 % N1. The EPR values appear to be correct though. It sounds like Alex is a real 767 driver, so I would appreciate his response as well as from CS.
