I have been struggling with static port issues. I have finally settled on a fix that still gives a bit of lower pressure than atmospheric at cruise speeds. At 170 MPH TAS, I am having to remove 6 MPH via the EFIS to get an accurate TAS and remove 8 MPH at 190 MPH. This is bench marked against 4 point GPS runs.
Clearly this lower pressure at the port is also causing my altimeter to read higher than it should. However, I don't have the tools to figure out how how far off it is. Can anyone help me figure out my altitude error, based upon the known airspeed error?
Thanks for any assistance you can provide.
