Import realistic autopilot features but not the anachronistic
features in the Lake of Constance version:
* Models/mesh_pedestal.ac: import from the Lake of Constance.
* Nasal/mk-ap-helper.nas: import from the Lake of Constance but heavily
edited.
* Models/Lockheed1049h_Pedestal.xml:
- The parking brake, emergency parking brake, flap, gear and propeller
reverse levers (+ lock) are clickable.
- The course selector knob, autopilot and altitude switches work.
- The pitch wheels of the autopilot work.
- Clicking on the center either of the trim wheels centers the
corresponding trim in two seconds.
In the present state, only some autopilot modes are available:
* wing leveler (AP switch on, course selector off)
* NAV1 hold (AP switch on, course selector middle)
* NAV1 + glideslope hold (AP switch on, course selector right)
* Pitch hold (AP switch on, ALT switch off); pitch wheels adjust pitch,
not vertical speed.
* ALT hold (AP and ALT switch on); pitch wheels do nothing.
The real Connie did not (seem to) have autothrottle or vertical speed
hold, let alone GPS. It does not even seem to have heading hold.
These features remain accessible by means of the generic (F11)
autopilot dialog.
