[Flightgear-flightmodel] Landing Gear

[David M. <da...@me...>]

In my local code tree, I've added support for retractable landing gear
to src/Controls/controls.[ch]xx.  The following methods are available
in FGControls:

  void set_gear_down (bool gear_down);
  bool get_gear_down () const;

Instead of using these methods, though, it is a good idea to use the
property:

  /controls/gear-down (bool)

This represents the switch rather than the gear itself -- i.e. I've
moved the switch to the gear-down position, but the gear may or may
not be down or locked (that's up to the FDM).  Is there any reason to
model this as a floating-point number (0.0:1.0) rather than a simple
toggle, when the FDM will manage all the in-between states itself?

For now, I've bound the 'g' key to toggle gear-down.

If Curt decides to add this patch when I send it to him, then we can
link the property to the JSBSim FCS through JSBSim.cxx.


All the best,


David
