After practicing with the team this past weekend in Charlotte, two of us needed to fly north on Christmas eve to fulfill our Christmas commitments. There was a large system of moisture to fly thru on our way to Cincinnati and Detroit.
Both airplanes are G3X equipped with Dynon heated pitot tubes.
Both of us eventually suffered airspeed failures, with working pitot heats.
Pre flight showed pitot getting hot along with associated amp increase. Amp increase in flight was also verified.
I am theorizing that the copious amounts of rain we flew thru entered the pitot line and froze somewhere in the wing.
Has anyone else experienced this with a Dynon pitot, or any other heated pitot?
Is there a flaw in the Dynon pitot that allows water in?
Yes the pitot system passed the static check!
