High altitude stalls, the simulator just does not work. Years ago, I enjoyed hand flying to flight level. one climb required a slight turn just prior to reaching cruise level. As I rolled to the new heading we felt a very slight burble. I had maybe 15 degrees of bank. took out a couple of degree and the burble vanished. After leveling off and getting the books out, our cruse level was about 350 and the burble was about 340. At our flight weight we had something just short of 1.25 load limit. Well as I made the correct to the new vector, I exceed the 1.25 and got the burgle.
Was the wing stalled? One wing was and the other was almost. Was I in danger, no. It should be noted that the fight director, course was indicating this direction change. No harm, lesson learned!
