Hello Hotstart,
Since the latest update 1.5.2 I can't sem to get the aircraft up to M0.82 in the cruise, this seems to happen at even at light AUMs. I'm pulling about 97.8% @ FL370-FL390 N1 continuously and this is hurting fuel perf as well. At present I am at FL390, ISA +6, N1 97.7%, GW 15750KG, and she only seems to get up to M0.81.
Have you changed either the thrust values or drag values with this update?
Thanks for such an awesome product!
