I found a small conspicuity in YASim. The destructor of the fdm was
never called, therefore a modification of the heli fdm (not in cvs) did
not work after reset (I tie some properties and untie them in the
destructor, but the destructor was not called and the tieing failed
after reset. I don't know if any other parts of YASim need their
destructors, at least it wastes memory.
Another small fix I have made to the turbulence.cpp. The code needed,
that (a-floor(a)) is >=0 and <1. This is analytical correct, but
numerical only for "small" values. In normal fg-operation a in this
function is always small, but with unrealistic parameters in the
aircraft config file it is not and then fg crashes (instead a crash of
the aircraft or cataputling it far away).
"bind the visibility-property of the SGSky object to a property

caused a crash in YASim's turbulence code. While converting nil to

Nasal exception instead. Hopefully this won't break too much

- Moved AIModels/Traffic Manager related AI functions to a new file
- Rewrote the traffic manager so that the containers use pointers to
objects instead of the objects themselves, which will allow for a
more flexible memory management.
- Rewrote parts of the airport groundnetwork code, also because the
stl containers now contain object pointers instead of the objects
themselves.
- Fixed an uninitialized iterator in the AI distance tracking code
- Fixed flawed logic in some of the traffic controller's while loops
- Added a tower controller, which paces take-off behavior of AITraffic
in a more realistic way.
- Various other minor fixes and fine tuning.
More realistic calculation of vortices at the blades and therefore
real airfoil parameters can be used now (not to be mixed up with the
vortex ring state which is still not simulated), ground effect is now

- I tried glScissors, didnt work because clipping was done in screen

- Stencil buffer methods worked great for 2d panel, but messed up 3d

Generally you want point sprites for performance reasons when enhanced runway
lighting (and smooth points) are activated. Most hardware doesn't
accelerate the rendering of standard smooth points, so without point sprites
you will kill your night time performance if you turn on enhanced runway
lighting.
Note that enhanced runway lighting "breaks" our clever scheme to make the
runway lighting brightness vary with the relative view angle. This means
with enhanced lighting on, all lights are equally bright no matter what
direction you view them from. So perpendicular runways are just as bright
as runways you are directly lined up with (when enhanced runway lighthing
is activated.)
You can revert to the original lighting scheme by turning off enhance runway
lights, turning off distance-attenuation, and turning off point-sprites in
the rendering options menu.
maintainable. The rules are simple (extension functions are called
*with* the lock, which must be dropped before calling naCall(), which
grabs it) but the tracking of when the lock was held was getting a
little confused. Keep a "nasal call depth" count in the subsystem to
figure out whether we are making a sub-call and thus hold the lock.

I attach 2 new files and a diff file for the associated changes to add a

essentially the same data as /orientation/heading-magnetic-deg, it has to

generate the error properties for this instrument here rather than in
xmlauto.xml.
When this instrument is included in cvs, I intend to use it in the Hunter,
A4F Seahawk and KC135. After a bit more research, it might be appropriate
for the Spitfire and Hurricane as well. AJ would also like to use it for his

is reported correctly in the entity's property subtree.
- In AIMultiplayer.cxx, compute a velocity value in kts to fill in the speed

This patch switches to a much more sane method for ground track computation.
Thanks to tied functions, this is only executed when the node is read. This
will be done by the old & new HUD code, the latter of which won't have a

basically the same thing), and to avoid using static buffers and all, but

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

Here is one patch that to make FlightGear run without floating point

When AIFlightPlanCreateTaxi() function is called with the firstFlight
argument set to true, this is supposed to handle situations where the
the aircraft's timetable indicates it should have left between about 5 to
20 minutes earlier. In the previous version, all these aircraft started
taxiing from the first parking location available in the network, due
to the fact that the variable gateId was not assigned a value. In this
patch, route tracing starts from an assigned gate and the network node
following code is fast forwarded to a random location along the taxiways
to give a more realistic and natural distribution of taxiing aircraft
after startup.
This patch further addresses some weird ballet-dancing behavior that
aircraft were showing just prior to/right after parking and which was
related to a number of more or less duplicate waypoints in the transition
from createTaxi() to createParking() to createPushBack() to createTaxi().
Finally, a blatant typing error in the getParking() function was fixed.
at (lon, lat) coordinates -1000,0. This patch fixes the AIModels/Traffic
Manager side of things. The AIModels subsystems allowed the creation of
AIAircraft with non-existent 3D models. If such a model didn't exist, the
aip class didn't get initialized, resulting in the above-mentioned bogus
position information. Here I circumvent this problem by a) only interacting
with the tile loader if the model is visible (and hence has succesfully been
initialized) and b) by disallowing the traffic manager to create AIAircraft
objects if the path to the 3D model doesn't exist.

turbo/supercharger boost programatically by setting this axis to
values in the range [0:1]. It also adds a "turbo-lag" attribute (a
time in seconds) to engines implementing turbocharger spooling delays.
This isn't terribly well tested, but doesn't seem to have broken
anything.
I am attaching a trivial patch that changes the normalization from 24 to
12 in turn_indicator.cxx. With this change, the pa24 tc has a turn
indicator spin value in the property tree of 0.9996 and the same value
for the pa28-161 is 1.0, so there is no harm to a 24 volt electrical
system in this change. Should the battery or alternator put out a lower
voltage than 12 volts, the spin value goes down and the tc shows a
negative turn that increases as the voltage gets less. This file shows
you as the author. If you are comfortable with this change, commit it
to cvs and the tc will be correct even for 12 volt systems.
propeller pitch stops for constant speed propellers. The default
values are the same as the previous hard-coded values. The new
attributes, "fine-stop" and "coarse-stop", are documented in the base
package, Docs/README.yasim.
- remove cleanup handler that unlocks unused mutex
- make the result_queue a locking queue (blocking is only done in the
pop() anyway, and this isn't used in the thread at all)
- don't disallow thread cancelling in the request_queue's pop(), which
is the only cancellation point in this thread
This patch makes use of the vectors now available in simgear with that past
patch. And using that it simplyfies the carrier code somehow.
- Small additional factory's to the quaternion code are done in the simgear
part. Also more explicit unit names in the factory functions.
- The flightgear part makes use of them and simplyfies some computations
especially in the carrier code.
- The data part fixes the coordinate frames I used for the park positions in
the carrier to match the usual ones. I believed that I had done so, but it
was definitly different. Also there are more parking positions avaliable now.
