I find the visual AOA indicator on my Skyview hard to discern with a quick glance, but the audio feed makes the visual display redundant. Slow beep starts at the beginning of the yellow zone, and increases in frequency to steady tone just before the stall. It is much more effective than the traditional ASI and stall warning horn, especially for tight strips, since my minimum approach speed varies by as much as 15 KTs depending on weight. It helps me with beginner aerobatics, and unlike stick force, it is not fooled by aft CG, which improves safety at the end of a long, loaded, cross country flight.
It was a fun challenge to calibrate the system, I had a co-pilot fly the stall sequences so I could focus on pushing the buttons at the correct moment.
