Cross-Control Stalls, Babes, that's how you do it. All this back-and-forth about the ASI has it's validity, but, in general, the ASI readings can't be counted on. You should go to altitude and get into a slip and bring the nose up just enough to stall, or get close enough to feel your airplane's control response, and notice your ASI reading. This will show you the nose-down attitude and speed to hold to stay at a safe margin while slipping on final. You should pay special attention to the sound and feel of the airplane controls as you increase pitch and decrease speed to the stall or impending stall.
