Our d100 has suddenly started acting up. The first indication was with the altitude on the autopilot in that when the alt button was pressed the autopilot promptly climbed 100ft and then settled on the selected altitude plus 100ft. This happened on the return leg of the trip when it had worked fine on the way out. The following day it did exactly the same thing fine on the way out and the the ap altitude problem from the outset on the return flight. Additionally after about 10min the error Temperature unstable appeared on the screen and the horizon toppled in the sense it was convinced we were banked at 30 deg. In the most recent flight we had this error both on the out and return legs along with the 100ft offset on the ap altitude hold this time the horizon completely toppled.
It was cold on the first flight -8deg but not so bad on the recent flights being 6deg.
Any ideas?
