Reaching FL445, engines spools down to nearly idle without flaming out, IAS drops by at least 50% and lift seems to drop as abruptly. I’ve tested this with the three aircraft I have that are capable of reaching this altitude (CJ4, Longitude and F/A-18).
It seems that after SU7, there is some discontinuity in the atmospheric behavior at a little over FL445.
Noted this issue on build 1.21.13.0
