Hi Alea.....
If an Aircraft can exceed 85% of it's maximum
operating velocity of 0.5 Mach at 2000ft & achieve
Mach 0.89 what is it's maximum velocity at 35,000ft
when it's maximum operating velocity is 0.86 Mach.
You & the simulation are then implying a 767 can achieve Mach 1.4 at 35,000ft!!!!
Do you not understand what you are implying,commercial 767's are capable of
supersonic jet fighter speeds at 35,000ft.....
This is just pure nonsense...........
