AI aircraft are out of range or the piloted aircraft has no radar system.
These computation include range, bearing, and angular offset relative to the
piloted aircraft. This gives some external script the control the behavior
of the AI aircraft relative to the piloted aircraft without requiring a radar
system, and without requiring the AI aircraft to be within radar range.
flightplan. Such aircraft are given some initial conditions that they
fly with. They proceed on in "freeflight" mode indefinitely. For example,
there is a refueling demo where the tanker starts at 3000', 280 kts, and
in a 15 degree bank, and then continues to orbit indefinitely.
For these aircraft with no flightplan, I have added several control nodes in
controls/flight that allow a script or menu or external application to set
heading, altitude, bank angle, and speed. This permits some level of interactive
or scripted control over AI aircraft.
are taken down by the C++ runtime environment. This will later be done
with runlevels. Why would we want to run nasal code in subsystem
destructors? We don't really. But some data structures may use nasal,
which are normally created/destroyed during runtime. And these will
also be destroyed at fgfs exit. In the past things like these didn't
happen, because someone had disabled all subsystem destructors ...

SGPropertyNode to guarded ones. This is also done for JSBSim/JSBSim.hxx,
for which JSB had given explicit permission a while ago. I postponed that
back then, but now is the time.
color group /sim/hud/palette/color[*]/ to the active group /sim/hud/color/
if they really exist. (Parameters like <antialiased> can be set in the
active group and be left alone, or set by each <palette> color group.)
into the <color> group, but that's because on HUD color changes a whole
"color" set from /sim/hud/palette/color[*] is copied to /sim/hud/color/, and
antialiasing needs to be considered with that. (I'm not entirely happy
with the property names yet.)
