Salute!
PEI. And Hans.....
Hans is describing my old VooDoo approach to the infamous “pitchup”. The stick got lighter and if you ignored the wing rock and buffet and then pulled more, then guess what? Duhhhhh. We had a manual limiter when not in AP control stick steering, and it took over 60 pounds to overcome. Then you hit the pusher.
The Viper control laws did not command any control surface opposite pilot input until AoA was above 30 digs or so. Then it removed your pitch and roll authority! It then applied anti-spin rudder. Meanwhile, your stab was fully deflected to get the nose down but could not help - you were in a deep stall. Engage and hold the pitch override switch and rock out of the stall. It was hard to get there, but after the new switch we could get out fairly quickly with 10,000 feet or so below. Maybe sooner if you had practiced, heh heh.
So bottomline, is unlike the MCAS, our FBW did not put in commands except as described above. It limited rates, gee and AoA. No matter how much you yanked and banked. About 35 pounds back stick and 17 pounds for roll.
Later, and we can move to Tech Log
