The manual states to consult the POH for the stall speed. Do all L4P's stall at the same speed? I know all GIII's don't. The only way to get an accurate stall speed is to do a 1G, straight and level, power off stall. Then you know what to enter in the AOA for your airplane. Or you can use the POH data, but that defeats the purpose of the AOA, you might as well just use the ASI. Common guys, these are not unstable computer controlled fighters. Learn to fly your airplane, learn to fly a stall, especially if you are going to do acrobatics.
