Autopilot questions

[zahnartz62]

I am learning to fly in Single Player Cross Country mission using the Bf110.. I RTFM about an autopilot,Key A, mentioned but not explained..I use Saitek x52 pro button and get Kurssterung Mode. The manual suggested A would fly AC for me but I think that applies to complex enenmy present missions, which I have not yet tried. Turning Mode On seemed to head my Bf110 for the ground! Maybe I turned mode off too soon and it would fly crosscountry course as on map.
The Bf110 has Course Autopilot deviation under gunsight which I assume simplifies pilot steering on course. I also see Directional Gyro (one article said it must be reset every 15 minutes) and below Course Autopilot Preset which I assume also guides pilot steering. Repeater Compass has course setter button and there is a Course Autopilot Adjust Course R&L box, left side at window level.
I got one reply to previous info search that suggests the autopilot is not a set/forget device so I can read a novel..but a steering simplifier. I find 6 Course Autopilot commands too.
I want to understand the cockpit and would appreciate information. I have googled for articles, searched the forums for answers, and thought I would ask the experts again.Many thanks
