Hi all...
Although I dont have a Dynon display in the cockpit, I am using the Dynon AOA pitot probe for pitot (total) pressure only - meaning I don't have the AOA line hooked up.
I got my bird flying and we found that when flying with the chase plane at 140 kts, my EFIS airspeed is 135 kts and my mechanical ASI is showing 130 kts. (the difference between my EFIS and standard ASI gauge tells me that the mechnical must be 'broken' since they are both reading the same pressures).
Question - do I need to do anything to the Dynon probe in order to use it as a standard pitot probe only?? I squeezed the aluminum air line closed on the AOA side. That's about it. Tony at SafeAir1 said that I may be seeing slightly lower airspeeds due to the drain ports? Are they tied together in some way?
Thanks for all your help!
