VOR disparity

Make that the last three years {;-)


Rich, there ought to be a little tweaky either on the rear of the OBS case
or by removing a knob and finding a hollow shaft for a long, tiny
screwdriver. Find your appropriate ground checkpoint using (as the fellow
suggested) the AFM and tweak it in. Save yourself a few tenths of an AMU.
However, you are merely adjusting, not CALIBRATING, which requires a
certificated repair station.

VOT first, the the ground checkpoint, then the approved airborne. Jim Weir
has also been working on a navigational tester in Kitplanes for the last
few months.

Aha! Yoost like de compass, you betcha. . .

I don't suppose there's anything one can do as easily for the bearing
displayed on the digital thingy.

Thanks, Jim

"little tweaky?" "digital thingy?" Come on guys, lay off the technical
jargon and use plain English.
