This is an enhanced version of the options patch.
It's more robust now, and gives some helpful information if something
goes wrong. Also the naming in the options.xml file has changed to the
syntax David suggested.
Since no one objected to the patch I think it is safe to included it.
class, FGModelPlacement, while FG3DModel retains control of animation.
This way, we can have a single, top-level placement, but multiple
layers of nested models underneath. To include a nested model, use
something like this in the XML wrapper:
<model>
<path>Models/Stuff/my-component.xml</path>
<offsets>
<roll-offset-deg>45</roll-offset-deg>
</offsets>
</model>
contain colon-separated ranges. For examples, winds from 180 degrees
10 knots gusting 15 knots would be
--wind=180@10:15
Winds variable from 180-220 degrees 5 knots would be
--wind=180:220@5
FGEnvironment does not yet support variable-direction winds, so
nothing will yet happen in the second case.
simplistic, text-field oriented interface for major property groups.
The JAR is now executable, so the program can be launched with
java -jar fgfsclient.jar <host> <port>
Modifications to support querying navaid database by station ID (not just
frequency.) Some corresponding changes to testnavs.cxx to test new
functionality.
This is a small patch that makes the autopilot work much better with big heavy
airliners as well as the small Cessnas. Of course this doesn't address the
way autopilots should be modeled.
But by making a couple changes the "George" is now capable of landing either a
C172 or a 747 very close to the center line of the runway with a moderate
cross breeze (15-20kt).
The changes:
- Added turn configurability so that things like Max Aileron and Roll can be
configured per aircraft.
- Enhanced localizer routine (NAV mode) to begin lining up the aircraft as soon
as the cone is entered. The former model is adopted for the last 5km of the
approach in order to ensure greater precision (makes a very slight difference).

/environment/density-slugft3 was flagged as archivable.
2. Density should no longer be archivable anyway, since it is
calculated internally and not directly settable by the user.

property has been removed, and the /environment/density-slugft3
property is read-only.
Fetch all pending remote fdm network packets so there is not chance of

Add support for driving control panel lights.

won't apply the right gross weight due to fuel differences.
When solving for zero force, do so in the global frame, not the
aircraft's. In principle, this shouldn't matter (zero is zero in all
frames), but in practice this should help to avoid oscillations.
Calculating lift as force perpendicular to the ground (and not the
wing plane) is clearly the Right Thing, anyway.
Also added support for a /yasim/gross-weight-lbs property, which
should be generically useful.

the all four of the other variables are perfect. I believe this should
fix the solution failures under gcc 2.95.2.
implicitly in PropEngine by disallowing negative torques, but that was
removed at some point. We really need the explosion protection here
at the source.
This patch adds "elapsed time" support to the sound code.
It is now possible to define <internal>dt_play</internal> or
<internal>dt_stop</internal> instead of a propery in the <volume> and
<pitch> sections of the configuration file.
This is a small fix for what turned out to be a major bug. Ground elevation
was calculated incorrectly when distant from one of the view locations. This
resulted in several problems including bizarre gear trimming, mid air
"crashes" (as in thinking we hit the ground) and so on when close to or on the
ground.
Unfortunately it does require a second ssg traversal when in tower view
(only), but the increased load isn't all that noticable. For the time being
this really is the best solution. In a future update I will be eliminating
the unecessary per frame traversals for the static views (without having to
maintain multiple ssgRoots).
When we go to multiple FDM instances we will perhaps need to put the ssg
traversal and ground elevation queries for the FDMs into an event timer that
updates the FDMs ground elevation in a round robin fashion (maybe every 1/n
seconds where n is the number of FDM instances running).
