Compass drift in gyro compas
-
Hi the PA-28 warrior II is a fantastisk AC, congratulations, but lately i have found that long flights on ap with heading engaged, results in compas drift, (that is ok, it is normal in real life also. the problem is here that the drift can not be reset. currently the instruments indicate course 200, but the ac is pointing 180 on my Skydeamon navigation that i use irl. have tried ctrl d, and turning the gyrocompas (that matches the magnetic by the way) design flaw or fault 40 ? brg peter grumman aa5 driver

i started out abt 1 hour ago going straight south both on gyro and alcohol compas.
engaged autopilot with heading and alt on
abt 90 minutes later both the gyro and the alcohol compas has changed heading, but the heading bug on the gyro is still placed on 180 deg, so is it compas/gyro or ap that is at fault ?
