Good evening,
KAP 150 Autopilot; It will pass the self test both on the ground and airborne. It will consistently engage in AP, ALT, HDG and NAV modes while on the ground but it will not engage in HDG or NAV while airborne. I can use AP and ALT modes while airborne. Seems odd to me that it will engage in all modes on the ground but then loses HDG and NAV only when airborne.
Any of the KAP gurus on here that might have some advice or simple troubleshooting that I can do before engaging an avionics shop for their services.
Thanks in advance,
Jason Calloway
