I have an S-Tech 50 in my 180 that is driven by an Aspen Pro with GPS Steering and other Nav. magic provided by a Garmin GTN650 in my 180. This last couple of flights the auto pilot would heading wander every now and then when coupled to the GPS but it would always resume normalcy after I disconnected it and re-engaged it.
This last trip it did the same thing on the way and then on the way home it promptly wondered a bunch so I switched to heading bug steering on the Aspen thinking the GPS was wonky and it wondered there as well then croaked altogether and the indicator went dark and won't relight or go through the test cycle.
I ended up hand flying an 8.2 hour trip in ugly conditions so HELP! I've got a couple more big trips coming up in two weeks. I called my normal shop for all things magical and he asked about the turn coordinator which seems fine (no flags or excessive noise) but unfortunately he's slammed for 6 weeks so he suggest I unplug it clean the plug and try again. I peaked under the dash and it is plugged in so I'm going to give it the old Maytag try this evening and see what happens, any other suggestions?
Thanks,
Kirby
