In this video an F-16 goes into a dive after the pilot loses consciousness. The Auto-GCAS corrects to avoid a crash, and the pilot regains consciousness and pulls up even harder. Why doesn't he pass out a second time?
According to this article and the G-force meter (at the top left) the pilot:
- Goes into turn and loses consciousness at about 8g's.
- The Auto-GCAS rolls and pulls up to a limit of 5g's.
- The pilot recovers consciousness and pulls up to 9.1g's.
- Pilot responds to radio calls to cancel the exercise and gain altitude.
It seems he held the recovery for quite a bit longer and at higher G-forces than the turn that made him pass out. I assume he also didn't have time to do anything breathing exercises or preparations for a high g maneuver. He is also experiencing the G-forces in the same direction both times (pulling back on the stick).
So why didn't the pilot pass out the second time?
