Gents,
I have a Dynon 180 with the AOA system installed. The AOA is calibrated and I have checked it several times over the past 110+ hour in my RV-7A.
I have it setup with a progressive tone. About 5-8 knots above stall it will generate a beep. As the speeds slows the beeps increase in numbers.
I have approximately 250 landing in my RV. I give most of them an 8 out of 10. Sometimes I get a beep, sometimes I don't. However I have landed slow and am surprised that most of the time I never get a beep.
The AOA system measures pressure at the pitot tube. When landing the wing is in ground effect and the pitot tube is rather close to the ground and in ground effect. This makes me wonder if the AOA/Stall warning isn't very accurate when in ground effect.
During landing I keep holding the plane off the ground expecting I hear a beep indicating approaching stall speeds. Most of the time I touch down and hear nothing. I am chasing a ghost?
Any thoughts.
