Every now and again I forget how I did things in the past, (including procreation*) so here we go...
On my Bendix-King Radio Stack, etc, Autopilot (Ap) also has Heading (Hdg) and Altitude (Alt) selection buttons.
This works fine, when I want to engage all of them, but sometimes I wish to select Autopilot (Ap)and maintain Altitude (Alt) but leave Heading (Hdg) switched off, so that I can manually vary my route.
On some of my aircraft, BOTH Heading and Altitude are fixed as soon as I select Autopilot (Ap) even with Heading (Hdg) button switched off!
I suspect that there may be an entry somewhere in the Aircraft.cfg file, where the "Autopilot" preference options, "Heading and Altitude", can be pre selected?
