I've been chasing a static position error at the start of my phase one that had altitude errors with airspeed, consistent with what many go through. Alt errors and TAS variation vs GPS 3 ways by >100 ft and up to 14kt at highest speed respectavely, reducing with reduced airspeed.
I got the errors down using the Brantel rivet/washer (0.080" proud) to less than 40' and 2kt across the speed range (TAS vs GPS GS using 3 ways). My DA's needed to vary due to WX, but they were within about 500' in all runs (roughly 5500' at 4600' msl).
I think I'm done with this effort. IAS is of course off, but that's just physics.
Does this seem reasonable?
