RE: Smilin Ed (#4102)
I still think the attitude on this thread, regardless of make of plane, seems to be that response to a stall warning has to be super fast. Does it?
Generally speaking, no. The time available for an action to avoid stalling depends on how rapidly the stall is approaching. Most airplanes, including the A330 in Normal Law, will have a stall warning margin of the order of 3 percent of the stall speed. In certification tests to determine the stall speed, the speed is reduced at the rate of 1 knot per second until the airplane stalls. If the stall warning is set to occur 5 knots above stall speed, then it would occur 5 seconds before the airplane stalls.
A glance at the AoA, should quiet any fears. IMHO, there should be an independent AoA readout available at all times.
I'm sure any testpilot would agree totally. However, I'm told that, generally speaking, airline pilots have no use for an AoA indicator.
