Good that your company has learned from the AF accident. I was in the sim 2 months ago, and still doing stalls at 5000ft by chopping the power and watching the speed bleed off.
You've presented an interesting scenario. No doubt the ASI indication of 30kt was due to icing, and the resulting error in the wind readout when the TAS is compared to GS.
A 15000ft loss in altitude is certainly eye opening. I still wonder why some airlines (including my own) still want us to maintain altitude during a stall recovery
