>AF447 was an Airbus 330 which does not have a physical stick shaker. It has a "Stall Stall Stall" warning that sounds and was likely drowned out by the other alarms that were filling the cockpit.
Just to be clear, an Airbus 330 won't let the pilot maintain an attitude that could lead to a stall, so it has a much higher degree of protection than a simple stick shaker. The situations in which these protections are turned off are situations in which a stick shaker would also fail to function reliably.
