Hi all,
My question of the day is:
using _/http://www.navfltsm.addr.com//_ i've done a lot of flying.
But on some of the longer flights I'd like to try autopilot for
heading/altitude (Cessna 172P) I'm usiing MacOS 10.3.9 and in the
autopilot setting, under Heading, there is True Heading and Heading
Bug. What's the difference and how are they used. When I try and put
in the magnetic heading I want to fly, the plane just goes in circles.
Also, does the NAV 1 CDI work and how? again, I just go in circles
even with the NAV 1 set to a VOR.
Any help would be appreciated,
I believe the default C172 impliments a KAP140 autopilot unit which
overrides the autopilot menu. You have to interact with it via panel
clicks. I haven't fully figured it out, but it will act as a wing
leveler, heading bug hold, altitude hold, (rate of climb hold?) and I
think it will track the CDI/GS although I haven't dug in far enough to
figure out how to do this.
Regards,
Curt.
