This is basic high altitude flying -
We cruise at 2.5. -3 degrees NU since jets airliners have been flying.
Approaching TOC our pitch attitude is perhaps 1 - 1.5 degrees NU higher(800-1200 FPM climb). So 3 - 4.5 degrees NU would be expected.
Putting an airplane in a position contrary to basic flying rules, and then blaming the airplane, isn't the right path either. Ten, 15, or 20 degrees NU at altitude is crazy. And the total time of total air data failure was under 25 seconds, and both were fully recovered in approx 45 seconds(?).
This is basic attitude flying. Flying isn't a game. Chasing a FD for 2,000 hrs isn't flying, it's playing a video game. Lord help us is the video game doesn't work correctly.
