No need to introduce seat shakers though. Stick shakers are a tried and tested way of attracting a crews attention. But they aren't part of the AB FBW philosophy and it might be quite a wrench to introduce them now.
Do you really think you can shake the short Airbus stick sufficiently to draw attention without also making control inputs?
And what if the pilot is not holding onto the stick when the alarm is triggered?
Then again, how would you alert the PNF?
It is relatively easy to shake the seat and no chance of unintended control input. It
will get your attention. And it doesn't occupy your overworked visual-aural channel.
It isn't part of AB FBW philosophy because the aircraft were supposedly virtually unstallable. Guess that bit of philosophy needs a revisit in light of current experience
