Steve, I simply pressured up the pitot line and called it quits. A pitot
leakage of this sort is found on many Piper aircraft such as the Warrior
and Cherokee. When I performed a static test with a "calibrated"
pressure source, read that as "homemade manometer", the Dynon read from
6% high to 2% low, while Van's analogue gauge read from three to five
percent low. I wonder what the error will be in flight.
