JP Dice Posted August 19, 2018 Report Share Posted August 19, 2018 I have an Aspen setup with STEC-30 AP and Garmin 430W. When I'm commanding the AP with either the heading bug or have GPSS engaged - I notice the turns seem to be at 1/2 bank instead of standard rate. The means the the AP will easily blow through the final approach course on an instrument approach. Is there anyway to change the turn rate on the AP configured with the Aspen? Thanks!

N201MKTurbo Posted August 20, 2018 Report Share Posted August 20, 2018 That is usually a setting in the autopilot. It is usually called the bank or turn limit. An autopilot sees an error from whatever is controlling it. It turns this into a bank angle proportional to the error. The bank has to be limited or the plane would roll inverted with a large error. I've never worked with your autopilot, but it has to have this setting. Quote Link to comment Share on other sites More sharing options...
Niko182 Posted August 20, 2018 Report Share Posted August 20, 2018 mine has the same problem. I just decided to hand fly the plane on approaches. best fix is most likely the 3100 upgrade. Quote Link to comment Share on other sites More sharing options...
takair Posted August 20, 2018 Report Share Posted August 20, 2018 I know that with the Century AFCS there is an adaptor that requires adjustment. I suspect that yours needs some tuning. It should be able to manage a 30 to 45 degree intercept angle. Check with your avionics shop. Quote Link to comment Share on other sites More sharing options...

JP Dice Something is not set correctly. I have an Aspen setup with an STEC 60. It will fly either standard rate or something less depending on airspeed and angle of intercept.

OR75 Posted August 20, 2018 Report Share Posted August 20, 2018 There could be 2 settings that may be off : - the bank limit - the gain likely the bank limit from what you describe Quote Link to comment Share on other sites More sharing options...
glenn reynolds Posted August 21, 2018 Report Share Posted August 21, 2018 My ovation with a garmin 530 and king autopilot did the same thing. I flew it to executive autopilot in sacramento CA and they fixed it and a bunch of other little issues in less than three hours. Now it works like a charm. The two other avionics shops I tried, just poked at it and said it was an old autopilot. Executive simply said it needed to be adjusted and they promptly did so. The lesson I learned. Bale as soon as the prospective avionics shop starts to demonstrate a lack of experience FIXING the issue vs simply replacing parts. Good luck Quote Link to comment Share on other sites More sharing options...
