FGExternalPipe is destructed.) This leaves the name pipe hanging around
even after flightgear exits, but assuming we put the files in /tmp that
shouldn't be a big deal.
ExternalNet interface:
- allows a much more closely coupled execution. A remote network FDM will run
at it's own rate, and maybe a particular data packets will come, maybe it
won't. This makes it very hard to control timing and keep the animation
smooth. There are also cpu scheduling issues with running multiple
processes on a single machine. The linux scheduler by default runs at
100hz. If an FDM process uses a sleep/alarm system to avoid wasting
CPU, it will be forced to run at 100hz, 50hz, 25hz, 20hz, etc. This
makes it *impossible* to serve a display system running at 60hz without
dropping frames.
- the downside is that the FDM process must now run on the same machine as
the master flightgear process.
arrays of insufficient size are allocated in prop_picker.cxx ( size()
don't count the null char ) and strcpy is writing outside the allocated
array. A patch follow.
I've updated the instrument modulator code to allow tricks like the one
described by Andy. It is now possible to define <min>, <max> and
<modulator> in one layer and if <min> and/or <max> ore within the range
of the <modulator> tag, their value will be honoured.
So, if you define
<layer>
<min>0</min>
<max>50</max>
<modulator>100</modulator>
</layer>
The value will stay at 50, until the modulator forces it back to 0.
- NED and UVW are working correctly
- knots is giving true airspeed instead of calibrated airspeed
- mach is not working at all
This desperately needs a trimming routine.
earlier, before fgInitSubsystems().
Modify fgInitPos() so that the plane is not automatically aligned with
a runway when an airport is the reference point unless (a) a runway
was explicitly requested, or (b) the plane is on the ground with no
offset distance specified. To set up the plane lined up on an
approach to a runway, use something like
fgfs --airport=CYOW --runway=32 --altitude=300 --offset-distance=0.5
This way, it's possible to specify a starting position relative to an
airport without getting snapped onto a runway approach (unless you
want to be).
better scheme.
While it's true that the actual ILS indications are unreliable when
far off the approach path, the ILS is not out of range -- you can
still ident it (an essential part of any approach procedure), and the
indicator will usually be doing something, however bizarre. The
current scheme did not allow the user to ident the ILS until
practically on the approach path.
