Hello Libretto

Thank you very much for update the airfile right now I'm testing it and no over limits reading show very good!!

I think the flightdynamics is much better then the standard CS model

However I realize on both model 757 and 767 just after take off when my aircraft is light 40% fuel on board and no full pax and I engage AP and FLCH or VNav aircraft climb very rapidly 6000 ft per min
I understand the fact that aircraft have very powerfull engines but I'm not sure if real aircraft climb that fast .
so for now I am using the v/s mode and about 2200/2500 ft p min
and my cost index is 80

I would like to add that this has existed from begining ver 4.x to 4.3 and before I replace airfiles by Libretto

Please let me know guys how is the climbing with VNAV and VLCh in yours machines

best regards
and many thanks for update the airfile libretto
