When climbing, in the pattern or on final I always keep an eye on the airspeed.
An AOA gage would just be another item to keep an eye on; unless it has an audio
warning. Then it would be very valuable. Without an audio warning I don't
see the point.

This might not be totally applicable to Kolbs due to their (relatively)
narrow speed range, but in the wider aviation world, you'd ignore
airspeed & monitor AOA. Reason is that 1G stall speed can change quite a
bit with gross weight, but angle of attack does not. Same applies to
optimum best angle and best rate in climb.
With the right kind of audio feedback, you wouldn't need to look in the
cockpit at all. You could devote all your attention to traffic, etc.
The toughest approach for landing is likely an aircraft carrier; Navy &
Marine a/c use AOA for approaches.

There are 5/12 volt buzzers out there.. EBAY....and one could tap off
of the the output to the first red led in the schematic , whose link I
posted.. Herb

Herb,
That could work (as long as you don't expect the LED current to drive a
buzzer), but you'd basically have just a stall warning horn. Might as
well just have a tabbed switch, like a Cessna.
With a proper voltage controlled oscillator, you can have a varying
pitch tone (even configured to beep at different speeds and intensity)
so that with practice, you can actually *hear* best angle, best climb,
approach, impending stall, etc, all tied to AOA meaning it would work at
any loading of the plane.
Those who are really interested might want to spend some time with
Google & read up on what AOA can do, and how it works.

The current driving the led would not , by itself, operate the
buzzer....would require a Transistor..resistor or two..Herb

How would one compute the speed range of my mkIII and a Cessna 172? and
compare the results?
Never flown with an AOA. I think it would be interesting to play with to
learn what it does and how it would improve me and my MKIII's flying.
