Looking for some advice from anyone who has Avidyne 440 / 540 plus KFC 200:
So I took my plane out for a quick VOR departure and RNAV approach to land today. Wind calm.
With VOR, IFD indicates VLOC. The CDI on my HSI is giving the correct deviation when the course heading is set correctly but when the AP is engaged to NAV / CPLD mode, it turns the plane to exactly 30 degree left of the course and stays there even when the deviation clearly was on the right.
With RNAV approach, IFD indicates GPS -> LNAV +V. The CDI is again giving the correct deviation when the course heading is set correctly but when the AP is engaged to APPR / Arm mode, nothing happens. The FD isn't doing anything at all and doesn't fly from one way point to the next.
Before I ring my avionics shop, I just want to make sure that I have the right A/P settings. One thing I didn't do was to "Activate Approach" when I was doing the RNAV approach today. Would that have made an difference?
Thanks everyone!
