I have a problem with my static instruments surging in flight, it is most pronounced on the altimeter, which moves about 20' up and down (one hash mark) slightly more than once a second. Connected to the static are: altimeter, air speed, VSI, Dynon D10A, encoder, and Trio Pro Pilot.
So far I have blown out (no water) both pitot and static lines, disconected the system at the panel and left the system open to cabin pressure, Took the VSI out of the system, and checked for leaks (none), nothing helps. The movement is not a problem but my auto pilot has a slight twitch in the alt hold??? Any ideas?
