Angier,
<= div>You do need something indicating your compass error, even if it i= s zero.  I have a tiny placard indicating "zero correction".
A compass rose is the way to go.  Your GPS doesn't know = which way the nose is pointed, just where you are going.
<= span>Make sure you have everything turned on as if flying when you swing th= e compass.  It took me about five iterations to remove all error.

Subject: [LML] Re: Compass calibration

=0AIf you could adjust out al= l compass error, are you still required to have a correction card posted in= the cockpit next to the compass?
Also, is a compass rose of any practic= al benefit for checking the compass, given given the accuracy of on board G= PS units?
