I think I had something weird with the Inibuild A310, how with maximum “realism” options (whatever this means), the plane can overspeed at 440 knots at 11,000 ft without structural damage (i.e. crash in the game)?
I understand that reaching Mach 0.80 is doable at 35-40,000 ft but can these airliners reach such speed with the density of the air at 11’000 ft, assuming normal temperatures (approx. -5C)?
next is a screenshot showing the attitude of the aircraft, I let it like that for several minutes, nothing happened:
