How to adjust KAP-150 autopilot


dsking001

Recommended Posts

I have a KAP-150 autopilot with a GNS 430W and Aspen Evolution. My autopilot tracks the GPS course with about a 1/8 mile offset to the right. When I select the Heading Bug steering source (non-GPSS), the autopilot tracks a couple of degrees right of the commanded heading. 

 

Is there a way to adjust or fine tune the KAP-150 autopilot to track course centerline and the heading bug?

 

Thanks

Dan

Good afternoon,

On my KAP 100, there is an adjustable "roll neutral" screw next to the "NAV" button.

Insert a screwdriver in the "RN" hole and adjust this screw carefully.

With the heading bug centered and the plane levelled, engage the AP in HDG mode. The yoke shouldn't move. If you perform this adjustment on the ground, be sure that the surface is levelled.

Dan right in your backyard is John Milker Crystal Avionics @ New Braunsfel

He adjusted my 150 a couple weeks ago.... Now dead on.

dan +1 for  rocketavaitor...but if you try it on your own know its very sensitive..I did mine yrs ago in the air, picked up a strong VOR signal and slightly adjusted the little screw that G man above mentioned until it stayed on course..Right now my S-tec 55X is doing the same thing but I've been living with it.
