requested parameters to determine if this should be an on-ground vs. in-air
start. The problem was that we never defaulted the value to anything so
if we didn't match an in-air condition, we simply inherited whatever value
was there from before.
scene management code and organizing it within simgear. My strategy is
to identify the code I want to move, and break it's direct flightgear
dependencies. Then it will be free to move over into the simgear package.
- Moved some property specific code into simgear/props/
- Split out the condition code from fgfs/src/Main/fg_props and put it
in it's own source file in simgear/props/
- Created a scene subdirectory for scenery, model, and material property
related code.
- Moved location.[ch]xx into simgear/scene/model/
- The location and condition code had dependencies on flightgear's global
state (all the globals-> stuff, the flightgear property tree, etc.) SimGear
code can't depend on it so that data has to be passed as parameters to the
functions/methods/constructors.
- This need to pass data as function parameters had a dramatic cascading
effect throughout the FlightGear code.

maintianed or upgraded in a *long* time so it didn't support many new
features like the runway lighting. If anyone was using it for anything,
it should not be a huge amount of work to switch to the binary format.
SimGear includes a reader and writer for the binary format.
I modified the files in src/Autopilot to add waypoint capabilities to the telnet port.
'set waypoint <WPT>' will set the next waypoint.
'get waypoint' returns one string which is the list of waypoints.
'set waypoint 0' will delete the next waypoint.
appears still to be indicating.
Added a 'caged' property to the AI, for aerobatic work.
Temporarily disabled tumbling due to pitch, until I can learn more
about it.
Publish the current amount of tumble (-1.0:1.0) under
/instrumentation/attitude-indicator/tumble-norm.
Set a random value for a numeric property
Params:
<property> - the name of the property to randomize
<min> - the minimum allowed value
<max> - the maximum allowed value
The one to fg_init.cxx initialises the AI subsystem regardless of whether it's enabled or not so that later enabling by the user doesn't crash it, and the one to main.cxx avoids running the ATC manager and ATC display system unless enabled.
proceed to search for an VOR of that same frequency. On rare occasion
this search could return true with a far distant VOR and cause a small
amount of confusion.
I believe.) :-)
- The height of the navaid was not being properly converted to meters
before being used in our internal calculations. This caused the GS
to be placed too high.
- I was using the wrong trig function to calculate the current approach
angle of the aircraft. The distance to the GS source is the euclidean
point to point distance and represents the hypotenuse (not the ground
distance) so I need to use asin() rather than atan() to calculate the
angle.
- I was calculating distance directly to the GS source, rather than
taking into consideration that the GS transmitter projects a plane,
so I need to take the distance to the line where that plane intersectso
the ground. Previously, the way I modeled my distance calculation, the
GS transmitter effectively formed a 3 degree cone from the source. The GS
transmitter is usually placed a 100 meters or so off the runway edge so
the cone model could never bring you in to the touch down point precisely.
With these changes, the GS will bring you in precisely to the touchdown
point as defined in the default.ils.gz file (it wouldn't before.) The only
issue that remains is that it will bring you in to the elevation defined
in the ILS database, which doesn't necessarily match the DEM/SRTM terrain
at that point. Still on average, this will be a big improvement until we
can do a better job of getting the runway end elevations nailed correctly.
New panels are loaded now
New 3D model gets loaded
Reinitialize more subsystems
Add reinit() to FGFX, sound gets reinitialized
Still a lot needs to be done though.
that after a reset or reposition, several FDM variable were not unbound
correctly and left dangling pointing to unallocated memory. This wasn't
a crash type bug, but those properties then had bogus values. This
specifically prevented the turn coordinator gyro modeling from working after
a reset or reposition.
