After about 3 hours of scouring the forum I cannot find this addressed anywhere.
My new Aerocruze 100 (in a PA28-180) has a strange behavior that I can't seem to work out:
I lose about 50ft of altitude every 10 miles or so.
Even if I go into altitude hold and specify an altitude, it will just climb to there then gradually descend a few feet every minute. It *never* corrects - if I let it go it will go all the way to the ground. It has tension on the controls and it is in trim.
If I activate CWS and climb back up manually, it will still start to sink after a few minutes. Checking the altitude (double-press ALT) shows the actual altitude. Re-sync of the altitude has no effect. Deliberately misadjusting the altitude sync makes no difference.
I can't find any solid references of what each setup parameter does (microactivity, gain, etc.) and how they affect performance. I am using the default PA28 setup parameters. The local avionics guy only speaks Garmin.
TIA.
