KAP 140 Issue
I just bought a C182 with a Garmin 530 and a KAP 140 two axis auto pilot with Alt hold. On a recent flight, I was using NAV mode. To track the GPS TK, I had to adjust my heading on the HSI from the DTK by 16 degrees. I had the following information:
GPS TK 359
GPS DTK 359
Compass hdg 350
HSI hdg 343
CDI 332
Before I head to the avionics shop, I would like to find out whether anyone else has ever encountered this problem.
