I have discovered some anomaly with my Aspen Kfc 225 installation. It might be a wiring/ pin problem, but I have to solve it ASAP.
Then anomaly is the following:
When then AP or FD is ON, and the NAV mode is ON and captured, the HDG bug still works, and affects the AP. I have discovered this, when the ILS^ LOC was captured, the HDG remained on the intercept leg, and the AP struggled to keep the LOC. The GS was ok. Yesterday tested during my flight to Duxford, and it had a the same problem with normal VOR capture.
The GPSS works ok, it is a kinda HDG mode.
Additionally, when the NAV is on, the HDG knob is more sensitive, commands more abrupt turns. I have talked immediately to my installation shop, but they still work on it.
Any idea without looking into the wiring, but I can provide it too.
Sounds like a wiring issue with the course error signal from the Aspen into the autopilot, which is seeing the heading bug signal for both Nav and HDG modes. Is this a new installation or has it worked correctly and just failed?
Ít is new.
