1. Yes, I do, provided it turns out FBW Airbi meet criteria for their installation. It's stickshaker, not stickwaver.
2. Aural warning, already patented.
3. See 2.
Hi Clandestino, I see you are an equal opportunity commentor.
My experience with the rudder pedal shaker was that it was pretty vigorous and if such a shaker were to be bolted into a FBW control system, it would probably cause excessive motion. But the hand is much more sensitive than the foot, so you may well be correct.
Only problem I see with your comment 2 & 3 is that it doesn't seem to have worked in real life when the chips were down.
But I'm suspecting denial as being a root cause for lack of response among the 2 copilots. Something along the lines of, "How will we explain getting into a stall.?" How will we recover from it? Maybe it isn't a stall."
And the Captain was led down the path by the copilots who didn't want to tell him how badly they had lost control.
I've seen it before in aviation-sort of a better to die than to look bad attitude.
A pilot who maneuvers aircraft should be keeping a mental log of where their energy is. Something along the lines of: "I've gained 3000 feet, I must have lost 70 knots, but if I dive back down, I'll get it back."
The PNF seemed to be aware of how the PF was mis-handling the aircraft and should have been running a rudimentary energy tally. But it appears he was instead completely clueless.
Of course maybe I am expecting too much. None of the AF447 crew were ever tactical jet pilots.
