// search for the specified apt id and runway no
bool FGRunways::search( const string& aptid, const string& rwyno, FGRunway*
r )
there was a bug, in that each runway corresponds to *two* runway numbers
(eg 01/19, 10L/28R) but the function was only checking one. I've modified
it to check the supplied number against both possible numbers for each
runway.
Secondly, I sent in the function:
// Return the runway closest to a given heading
bool FGRunways::search( const string& aptid, const int tgt_hdg,
FGRunway* runway )
a year or two ago now when I first did the ATIS. I'm not sure what I was
doing at the time (copied most of it out of fg_init.cxx) but I don't think
it's ever worked, so here's a brutal modification that does!
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.
04Feb. Actually been running since the beginning of January with these
patches. All changes work without crashing with the current base package cvs,
but there are some visual problems with the views (other than pilot view)
without changes to the base package.
As soon as you can build test and commit I can add in those base package
updates that will make it all work nicely. I will also go through all the 3D
Aircraft configs to make sure the change in the "pitch-offset" for cockpit
views (see below) are made to maintain current behavior.
Here are the files (changes listed below):

Here are the two modifications I had to make to get flightgear (just
updated from CVS) to build. The first one is for being able to specify
SimGear's location at the ./configure command line, and the second one
is to be able to link.
Here's a change to the GUI property picker I did a few weeks back.
It makes the values in the property pick 'live' (and also re-factors
the picker code to use less arrays, this should be obvious from the
diffs). A good demo is to open up the engine node and observe the rpm,
cylinder head temp, oil pressure and so on while playing with the
throttle and airspeed. It's pretty rough (some rounding of digits would
help) but useful for testing (at least I think so). I'm not sure about
the performance implications either, but it seems fine for me.
All logs and log entries are now disabled by default, unless
explicitly enabled by an 'enabled' property. This works much more
intuitively with the GUI dialog.
the whole electrical system. We will also need a mechanism to kill
individual suppliers (such as the alternator), but this is good enough
for most training.
if the station is too far away. Instead, simply return the closest station.
All the code that searches navaids does it's own range checking anyway.
This will make the navlist query functions a bit more useful for other
types of functionality where you may need to lookup a station without
consideration of range (i.e. presetting your position relative to a navaid.)
a spinning gyro.
Changed FGInstrumentMgr to inherit from FGSubsystemGroup, greatly
simplifying the (already simple) class. I should probably rename this
to FGInstrumentGroup or something similar, but not today.
Added the gyroscopic turn indicator (part of the TC).
hemisphere the distance is positive, if you are in the departure hemisphere
the distance is negature. (Possible use for graphing approach distance
vs. glide slope or cdi.)
Fix memory leaks (PUI doesn't make copies of lists, so we have to make
our own copies and keep pointers to them).
Adjust for new method names in NewGUI.
Move the GUIInfo struct into the cxx file so that it's not part of the
public interface.

(I thought I'd slip this in along with David's change to the default menu
configure option. I believe that will cause a new config.h to be generated
which will cause a near complete rebuild of FG (as will this globals.hxx
change) so it shouldn't cause additional grief to have these happen at the
same time.)
menubar. This one allows regular command bindings, with the
(temporary) condition that every menu item must have a unique text
label. The new menubar is disabled by default; to enable it,
configure --with-new-menubar.
input bindings. They will work only with the latest CVS; otherwise,
./configure will disable them. There is a new command, 'script',
which takes a single argument, also called 'script', containing PSL
code (currently PSL requires a main() function).
Erik Hofman has written some more elaborate code for triggering PSL
code from drop-down menus and scheduling events; I will look at
integrating that next.
and property-multiply:
Firstly, change back to wrapping modulo the interval, with "min <= x <
max" semantics. I believe the previous implementation did that. The
inline function that Norman mentioned also does that.
Secondly, make it snap to the nearest value (min + N*resolution) when a
"resolution" tag is present, taking special care of floating-point
precision. Or perhaps specify "number of divisions in the interval" as
an integer, instead of "resolution" by which I meant a floating-point
"size of a division".
[also fixed]
While working on this file I noticed some potentially serious warnings:
fg_commands.cxx: In function `bool do_property_adjust(const
SGPropertyNode*)':
fg_commands.cxx:435: warning: control reaches end of non-void function
fg_commands.cxx: In function `bool do_property_multiply(const

Some more cmall changes to the SimGear header files and removed the
SG_HAVE_NATIVE_SGI_COMPILERS dependancies from FlightGear.
I've added a seperate JSBSim patch for the JSBSim source tree.
experimental lighting rendering (which is very expensive on my
machine, for example). To use distance attenuation,
/sim/rendering/distance-attenuation must also be true.
It adds a command line options to enable/disbale distance attenuation
using a property rather than using a #define inside the code. It also
adds a small change for systems that don't support the OpenGL extension,
so that the lights *do* fade away as they get furher away but they don't
get smaller in size.
property-adjust.
Modified property-adjust and property-multiply so that they always
work with double values, to simplify the code.
Factored out some common code.
Added a 'mask' argument to the property-adjust and property-multiply
commands. If mask is set to "all" (the default), then the command
works as before; if mask is set to "integer", it works only to the
left of the decimal point; and if mask is set to "decimal", it works
only to the right of the decimal place. This functionality is useful
for tuning VHF COM and NAV radios.
Ensure that if a condition for a panel mouse binding fails, other
bindings for the same area will have a chance to run.
Add a repeatable flag for panel mouse bindings (defaults to true).
