1 - You can modifiy the pro903 autopilot file located there : C:\Orbiter_Path\Sound\deltagliderIII\PROG (already explained in
the documentation if my memory is good)
The only parameter accepted is the launch heading for ascent autopilot and reentry angle for descent autopilot.
Once again read the doc or look at the in-panel checklist.
2 - M'y screen resolution is 1280*800, and in the parameters tab of the orbiter launchpad you've a field called "panel
scale", my current setting is 1.11 (so 'ive to scroll a little but the two mfd are in my screen)
Hope this help.
