Tried for an emergency landing in Bermuda today - the first attempt was about 140 miles short (okay, it's hard to estimate the precise ranges for the abort regions from the schematics in the manual, so no surprise here) - the second was probably okay, but then the AP lost roll control just before the hard part of the Nz pullout (I'm fairly sure there was a non-zero beta when Aerojet engaged, and it was trying to correct that while managing the pullout, which didn't go well). Surprisingly I lived to see 70.000 ft, but then it all spiraled out of control.
Aerodynamically the contingency aborts are just an extremely challenging regime - basically the AP needs to change within a few seconds from 'only thrusters do anything' to 'thrusters are far too weak to do anything' to 'airfoils start to jam because qbar is so high' - while you reach vertical speeds of 800+ m/s (!).
Yeah, that's right, the vertical speed is more than most planes will ever go horizontally...
Anyway, I think I'll just leave the remaining engine on for a few seconds more to stabilize the situation next time (I already updated the Bermuda regional texturing to show something closer to reality - seems it's quite densely populated...). Also there's now TAEM guidance for the airport - manage approach carefully, the runway isn't that long
