When I checked my system I found a tiny bit of moisture in the lines that had collected at a low spot. After removing the moisture, the error disappeared. I now check the lines periodically.

It is usually 30 degrees or more off of actual heading. Is there a calibration mode for the A/P? My device not infrequently messages that it wants to shut off and some times it does. At other times it has introduced errant output to the point I have to disconnect to avoid making unwanted attitude changes. A few times I've had it not want to let go and I have had to do the equivalent of popping the c/b. It seems to be doing this less and less and maybe the a/p heading is gradually getting closer to the Cheltons. Any thoughts?

Be sure to check whether the airport where you do your calibration has changed recently and if field compass rose (if there is one) has been updated to match it or you will mis-calibrate your compass. > > Dan Schaefer > > -- > For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html -- For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
