DFC
I don't suppose there is any danger that you walked in on a demo of how NOT to teach stalling!
As IRRenewal says stall speed with power on is lower than stall speed idle. That is usually stated for full flap and flapless in the POH for the A/C.
With elevator authority running out 10kts above stall, you are never going to be able to grease this baby on!
Let me know what type of A/C it is, I'll avoid it.
Is it that easy to become an FIC now....
But seriously though.........
Having said that, I just did a stint instructing away from my usual haunts and found differences in the way things are taught down there to the way I and my colleagues would teach. Not "bad" technique, but not what I would regard to be best practice. Not at the school I was teaching at, I hasten to add. But another on the same field.
There are maybe some standardisation issues at FIC level in the CAA. That one is down to the FIE's I guess....
