I had the AP/AI at my hangar attach a test apparatus on the pito tube. and the ASI was within 1-2 mph with every airspeed he dialed in. This was sitting on the ground while using either the wing static source, or behind the panel static source. Makes me think the ASI is okay, and that the problem is whichever source I try it's not truly static. I guess I will try seeing if the tube on the wing is not pointing in the direction of flight. I know many of the other aircraft I look at on the ramp and in the hangar have static sources on the outside of the fuselage between the firewall and the panel, so I thought that might help moving it there.
The altimeter is usually reading about 70-100 feet low, but since I can see the ground whenever I fly it hasn't concerned me. In a message dated 2/4/2012 3:11:30 P.M.
