Hello,

Any other AP would be unrealistic - I see no reason to use another one. The factory built-in is ok.

But If you want you could use the Default-One from the Cessnas. Simply add these to your panel.cfg:

[Window Titles]
WindowXX=Autopilot

//--------------------------------------------------------
[WindowXX]
Background_color=2,2,2
size_mm=250,504
position=8
visible=0
ident=RADIO_STACK_PANEL

gauge01=Bendix_King_Radio!Bendix-King Radio Audio,       0,  0,250, 44
gauge02=Bendix_King_Radio!Bendix-King Radio Nav-Comm 1, 0, 45,250, 92
gauge03=Bendix_King_Radio!Bendix-King Radio Nav-Comm 2, 0,136,250, 92
gauge04=Bendix_King_Radio!Bendix-King Radio ADF,       0,227,250, 65
gauge05=Bendix_King_Radio!Bendix-King Radio DME,       0,290,250, 65
gauge06=Bendix_King_Radio!Bendix-King Radio Xpndr,       0,353,250, 78
gauge07=Bendix_King_Radio!Bendix-King Radio AP,       0,430,250, 74

You have to replace the "XX" with the corresponding Window-Nr. which comes next, or, alternatively, you could replace an existing window with this one.
