Note that those properties are also writable. This is a good thing since
at some point we'll probably want a way to manipulate weather changes without
restarting.

I think we're all on the same page...but what i'm seeing is this:
The code in the last release displayed property values in fps "from" north or
east when using JSBsim. Those values could be changed during flight to alter
the wind direction or speed during flight. The values entered would be
interpretted as "from" their respective vectors. IMHO, without getting into
the internals, JSBsim and the interface to it was correct.
Best,
Jim
