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.
