This can be used to validate atomic branches after individual members
have been changed.

ends, and not meant to enforce/accelerate a decision.)

This allows to display objects that are in /ai/models/, but not managed
by the AI manager, and it follows fgfs' design principle that subsystems
should communicate over the property tree (if possible). This is a tad
slower, but the radar is only updated once every second.

The values are initialized to the shown default values if omitted.
These are the values of the former hardcoded constants.
The current code still has some rough edges, in particular memory still
needs to be deallocated where possible, and the actual use of the code
needs more testing. This code has been running without noticable problems,
so I think it's ready for some wider exposure. Detailed changes include:
- Finetuning of the SID/STAR data concept.
- Preloading of all SIDs, from one xml file.
- ATC determines which SID should be used and echoes this over the com1 or
com2 radio.
Again, the previous commit did not complete for some reason.

experimental: Only one SID per runway is supported, and the waypoints are
read from file at every request, which is not very efficient. The current
code is only executed when FlightGear is configured to use airport dynamics
data from the scenery repository, instead of the base package. Since the
latter is still the default, I believe that this will provide enough safe-
guarding to commit SID/STAR support in small, incremental steps.
Next step will be buffering and support for multiple departure routes per
runway.
Background are problems modeling the rotax 912 engine. The idle speed
of the real engine is about half of the speed I could achieve with the
default minimum manifold pressure. While on ground I can switch off
the engine by pulling the throttle. The audible difference between the
different minimum idle speed (real vs. simulated) is extreme. With the
patch I get quite realistic sound. For the rotax engine I use
min-throttle="0.05" which is half of the former default value.
localtime() is once commented out in simgear/io/sg_binobj.cxx and
a warning says the it can screw up sim time. This is only because
localtime() isn't thread-safe (and its thread-safe cousin localtime_r()
isn't portable). As long as all timing is done in the main thread
(which is the case) there should be no problem. Otherwise we'd have
to implement a simple mutex locked wrapper.
* Changed the runway XX. ATC message to actually report the real
designated departure runway
* In case of multiple active runways, select the one with a heading that is
closest to the direction of the ultimate departure destination / lines up
with the arrival path.
This gets rid of a lot of messy code. Although the performance is about
the same as the old code, there is the possibility of a big performance
boost if/when the polytope intersector is taught about KD trees.
- make some char* "const" to silence warnings
This removes the warning that (rarely) occurred if one wrote to a
write protected property with setprop(). While this was a useful
hint, it needlessly floods the terminal if one protected a property
intentionally. (Consider to add an SG_DEBUG warning instead.) It's
now the caller's job to check for the result if it actually cares.
some prepratory work for assigning different operations to different
frequencies. It also returns a stub for returning an ATIS message ID.
Currently, the ATIC information ID is hardcoded to "Sierra", which needs
to be replaced by a dynamic ID once ATIS services are fully integrated
with the new trafficcontrol code. At least, it's marginally more realistic
then the previous information XX. :-).
In multiplaymgr.cxx:
The length of a string property that is too big was written out in the message
even though the string was truncated. Also, it was possible to overrun the
message buffer.
In incoming messages, null-terminate the callsign to prevent any funny
business. Don't believe invalid string lengths. Turn the warning about unknown
properties from a warning into info; there are too many buggy clients out there,
not to mention people who add their own MP properties (hi vivian :)
and radials, as well the selected ADF frequency to be transmitted to Atlas
DT: Two minor modifications to the adf part to make it work, and some
testing.
* Some support for geometry information provided by the custom scenery
project. Current support is for AI groundnets and runway use files only
since this is a switch that involves a lot of data verification and
updating, during the transistion the actual path where the data can be
read from is user configurable. setting the property
/sim/traffic-manager/use-custom-scenery-data to true
will cause flightgear to read the ground networks from the scenery
directory (--{fg-scenery}/Airports/[I]/[C]/[A]/[ICAO].groundnet.xml to be
precise). Setting this property to false will retain the original
behvior.
* For departing aircraft, runway takeoff calculations will be done on the
basis of the performance database. For testing purposes, a performance
estimate for a heavy jet has been added.
Can't reproduce the problem that r1.103 meant to fix, but it
caused another problem: MMB dragging events weren't passed,
so e.g. power lever control in the bo105 stopped working.
T_PositionMsg had different sizes on 32 and 64 bit systems, which is bad when
a struct is put directly into an network message.
Try to work around this difference in old clients still on the network.
up in list/textbox etc. (This should really be separately settable
via style definition, but it's very rarely used and a change now
is probably not worth it as we'll probably switch to osgWidget,
anyway.)
there is no valid active runway. This is not ideal, since it masks underlying
problems - the real fix is to make the runway-use code more robust and
validate input XML.
instrument of the same name. In the future I'd prefer to rename the
instrument class instead (FGMarkerBeaconReciever?) but this is the safest
change for now.
Thanks (again) to Yon Uriarte for pointing out the problem (which seems to
affect MSVC more than gcc)
notion of a 'displacedThreshold'. Now there's just a real threshold,
displaced or otherwise, and people who care about the paved area can use
'begin' and 'end'. Thanks to John Denker for pointing out the confusion this
leads to. Using 'end' also gets rid of the 'reverseThreshold' name, which was
clearly a bad choice of mine.
saving for beacons, but since they're surprisingly few (in nav.dat), not a
an enormous saving in real terms. The major motivation is that marker beacons
don't behave like other NavRecords for radio interaction - they have no ident,
frequency or range (in the sense that NavRecord means them).
This makes taxiways smaller (important since at present there are so many).
Restructure the apt.dat parsing code to use a helper class instead of one long
function, and to do less work when parsing the file.
Some of these ideas come from Yon Uriarte's patches - thanks Yon.
This was lost when I stopped cloning the near camera to make the far
camera. The result was a lot of breakage, including explicit camera
configurations not working and various ordering issues too.
This seems to be accepted OSG usage for slave cameras. It's possible
that this order is important for rendering instruments that use RTT
textures on systems without frame buffer object support. I'm thinking
that the resulting bugs may be implicated in the "black rectangle" problem.
The near/far boundary, called "near-field", can be set to 0 which
disables the far camera and renders the whole scene using only one
camera. I'm hoping that this may be useful in resolving some
system-specific rendering bugs.
Various fixes were made to correctly render the scene using only the
near camera.

large vectors of referenced-pointers is a Bad Thing - copying on vector

static FGAirport helpers. As a result, another global index goes away. Use
the helpers to avoid ugly FGPositioned down-casts in various places.
Also converts the environment/METAR code to deal with FGAirport pointers,
instead of string identifiers, and contains work-in-progress code to implement
the AirportList dialog using FGPositioned. This isn't enabled yet for various
reasons, but is the final piece to allow FGAirportList to be removed.
gone. This is good news, since the old query was implemented as a linear
search, sorted by Manhattan distance, and with a warning not to use the logic
at runtime. Various systems (such as the Mk-VIII) do query such data often,
eg every second.
Also gets Point3D out of Airports/simple.hxx, as a precursor to removing it
completely.

required. As a result, the marker beacon list is gone (since beacons are only
searched spatially). In the process, clean up various minor things - most

const) which were previously tricky but now easy. Make it possible not to
index certain types (used for taxiways) and exclude anonymous items from
the name index. Related to this, clean up FGRunway further - remove some public
members, and fix a dumb bug of mine, where we create reciprocal entries for
taxiways.
This should make startup (slightly) quicker, and shrinks FGRunway somewhat.
Add a helper predicate to FGAirport to encapsulate the common 'does this
airport have a suitable runway of at least xxxx ft?' query. Also add a
FGPositioned filter built on the predicate, and a 'closest airport' helper.
"I've managed to fix this by differentiating rebuilding the 3D layers
(e.g. due to METAR updates) from rebuilding the entire environment (due to a
change in scenario)."
reverts one of my changes which ensured that the 3D clouds were updated with
METAR. Unfortunately this had the side-effect of over-writing the environment
properties, and therefore nuking the interpolation work.
Attached is yet another 3D clouds patch, to fix the following:
1) The 3D clouds were not modified by the cloud coverage, due to some problems with osg::Switch
2) METAR changes to cloud coverage were not obeyed.
3) Making changes via the Cloud dialog had no effect unless 3D clouds were toggled.
4) Cloud cover was too sparse.
5) 3D Stratus clouds caused performance issues on some hardware (fixed by removing 3D stratus from cloudlayers.xml - it will now be a 2D layer).
displayed garbage in the title line if one left a directory. Jester
spent a lot of time finding the cause: a bug that must have been
there since ... forever: fgfs reported to PUI the string addresses
as returned by SGPropertyNode::getStringValue() without considering
that this address isn't valid after the next write access to that
node! It's almost a miracle that it worked so well for so long,
despite that issue. (I also used to opportunity for some more
cleanup -- so I'm to blame for any newly introduced bugs, and
also for reverting some of Jester's cleanups. :-)
- Removes the cloud type re-use code - I think they aren't worth the graphical artefacts that they cause in light of Tim's improvements
- Changes the transparency of the clouds. Previously, the clouds were transparent at 0m distance, opaque at 200m, then gradually more transparent to the fog limits. This meant they were generally quite transparent. Now, they are opaque from 200m to 15km, then become transparent at 20km. A side effect of this is that the current textures could probably benefit from being made slightly transparent to improve the blending of the sprites against each other.
Here's a patch which refactors the 'plain' GPS code into a slightly
more manageable structure - i.e breaks the large update() method into
various sub-functions. I've tested the patch with B1900d, and things
seem to work as expected, but if anyone experiences GPS weirdness
after this is committed, of course please report it.
The motivation for this was helping me learn the code - I've planning
some changes in this area, and splitting up the logic will hopefully
make that task easier.
- updates how filtering is done on the various FGPositioned query functions - both spatial and ident-based.
- updates the KLN-89b / DCLGPS code to use FGPositioned for all Navaid/Airport queries.

deletion of pointer to incomplete type 'FGFixList'; no destructor called
