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.
