Speaking of Stick Shakers.....and I'm NOT trying to be funny or sarcastic here as I don't know.....what happens on an Airbus or any aircraft with a Side Stick? Does the Side Stick shake in the same manner as an aircraft with a yoke?
Airbus... No the (side)stick does not "shake".
Usually there would be no need for a "Stall Warner".. the "protections" built into the FBW prevent getting to an AoA where a "Stall Warning would be issued... These protections are primarily "Alpha Floor" where Full power is selected... wherever the crew have the Thrust Levers. This is not foolproof, since firstly it is disabled at low altitude [<100R] (as Habshiem showed), and secondly it is an Autothrottle function, so if ATHR is U/S or disabled (possible) it will not work.
Secondly, in "Normal Law" the aircraft will make it harder for the crew to pull back to the stall... if the stick is left "neutral" the AP would disconnect as you reached an AoA called Alpha Prot, and then maintain Alpha Prot (well short of stall). If you pull back on the stick, full back stick equates to Alpha Max, a higher AoA, but still short of the stall.
If all the above fail, or in degraded Flight Control Modes, and the aircraft exceeds Alpha Max / approaches a stall, there is an audible stall warning - it shouts "STALL" at you - again prior to the stall AoA. This is what happened to the Air NZ A320 - for reasons various the protections above did not work / were disabled by the crew / were ignored, yet when the "STALL" warning came they reacted.
The "STALL" warning" audio is therefore the A320 equivalent of a stick shaker...
