From what I've read in the past, Auto GCAS computes a 5G recovery pull. Speculation was that the pilot came to consciousness at some point during the recovery and applied some extra input to hit 9Gs.
- Rastonbury 6y agoPilot recovered while pulling 5G? I'd think they would have designed the GCAS to avoid a crash at all costs, regardless of the Gs required. Crashing is worse
- 35fbe7d3d5b9 6y agoIt is designed that way. It realizes that by defining a roll to level and +5G climb as a successful recovery, and preventing the aircraft from being flown into a condition where a successful recovery is impossible. So if you're flying right above terrain and you suddenly fly down, the airplane should accept your inputs and fly towards terrain until the moment recovery is impossible and will then engage. This video from the Air Force shows this clearly: https://youtu.be/Wf27X73jxlE?t=144 https://youtu.be/Wf27X73jxlE?t=144 The system allows you to fly low and fast (2300 feet above ground and 500 mph) until a +5G pull wouldn't get you off the ground, then activation.
