Heading's off a bit

[woneill]

My unit was recently calibrated. I now find that WESTBOUND the SKYVIEW agrees with my GPS and wet compass headings, but EASTBOUND it is off by +12 degrees. Also notice winds aloft are frequently exaggerated by +15~20 knots.

Should I have the unit recalibrated or is this an acceptable error?

Recalibrate on the ground (not moving). Then check to see if the unit agrees with your compass. My system agrees with the compass headings exactly while on the ground and in the air.

Thanks...much better now on the ground.

Will flite test tomorrow.
