Hi Gums,

I agree with you and Ian W - simple WOW logic for stall warning activation.
If I'm airborne - I want to know if the angle of attack is excessive no matter what my indicated air speed tells me. (There is no mention in FCOM about the >60kt IAS logic)

OTOH, seems the 'bus and other heavies use WOW for spoilers and such after touchdown, or am I off base?
If only it was that simple!

This extract is from Airbus Safety First Magazine Feb 2010: (my bolding)

"3.2. Hard landings
Among hard landings, one specific category has been identified where by the hard landing occurred after a bounce. They fit to the following scenario (fig. 7):

No engine throttle reduction (retard) during the flare
No ground spoiler extension.
Bounce induced by a too high energy level and by the lack of lift destruction.
Engine throttle reduction performed during the bounce
Ground spoiler extension if the retard is performed within 3 seconds following the first touchdown.
Severe hard landing due to sudden loss of lift leading to a fall from a height of about 5ft to 15 ft.

It has been established that most of the hard landings occurring after a bounce are severe."
