After doing a few stall maneuvers, I had the curiosity to analyse the Skyview download using the convenient help of SavvyAnalysis web site service (Using their zoom feature helps get precise measurements).
All tests carried at 3,000 ft at 1,200 pounds of load.
On power-off stall with full flaps, the stall warning triggers around 50 kts while on power-on with 1 notch of flaps it triggers around 60 kts IAS. The break on power-on stall occurs at 38 kts IAS.
The power-off stall did not produce a clear break so it is difficult to see where it occurred on the diagram but based on rpm increase following the break it seems to have happened at 35 kts IAS.
I feel comfortable with these figures, the stall warning gives plenty of time to react while not interfering in normal flight conditions. During slow flight the tone can get quite annoying but I don't consider this a normal situation outside the flare on landing. I rarely trigger the stall warning on landings although I can do it if I want to.
These pointers will help me get less stressed on landings in gusty wind. I am curious getting feed back from other -12 pilots as well as advice for any change you would recommend.
