1. Interesting concept: "Anticipatory Instrumentation". Extrapolation is of limited value, and not to be relied upon.
2. The Updraft could easily have been well in excess of 10k fpm. I used 5000 as a low, and conservative, value.
3. VS not reliable via IR. Airspeed not reliable via IR.
4. In airdata compromised situation, you believe the Baro VS? Let alone a smoothed combination of the two? Especially in the presence of rapidly moving temps and pressures?
5. There is a good deal more evidence to support UPSET caused loss of speeds, than ICE.
6. For that matter, there is plenty of evidence to suggest the upset was caused by this environment, as well as UAS.
7. At Loss of Auto, the airframe was losing altitude, and vertical acceleration. Combined with Nose Low on the screen, what would you do? Wait, right, ask your advisors/instructors?
Challenge. Describe the accelerations on the Pilots' bodies as a result of this maneuvering.
