/sim/ATC/radius should be a nummeric estimate of the size of your aircraft. A small aircraft fits into a large parking, but a large aircraft does not fit into a small parking space. Because the AI part of radius is also used for slightly different purposes (prioritizing gate assignmments, the given valuem may deviate slightly from the real aircraft size. See http:/wiki.flightgear.org/Aircraft.radii for an overview of currently used values for the redius property.
/sim/ATC/flight-type can be any one of "ga", "cargo", "gate", "mil-fighter", "mil-cargo", or "vtol". See http://wiki.flightgear.org/Interactive_traffic#A_technical_perspective for more information.
optionally, the property /sim/ATC/airline can be set set to a three letter icao airline code. By way of illustration, I will commit a number of startup preset files setting these properties shortly.

This fixes at least the startup process.
If an ambigous fix name was presented with --vor=ID or --ndb=ID
present a list of matching records along with frequency and
position in the console to give the user the chance to pick
the correct one by adding the frequency with --vor-frequency=nnn.nn
It does not yes solve the issue when the user relocates using the
GUI dialog. This requires some GUI and Nasal hacking along with a
new Nasal helper function "navaidinfo".
New "auto-position" switch to always use closest tower for tower-view.
Exposes new "/sim/airport/closest-airport-id" property.
Display closest airport on groundradar by default.
Rename ATC/atis.[ch]xx to ATC/atis_mgr.[ch]xx, to avoid confusingly
having 2 atis.cxx and 2 atis.hxx in the source tree. Also fix a copy
and paste error in src/ATCDCL/CMakeLists.txt.
This patch removes the conditional compilation of ATCDCL, compiling both
the old and new ATC systems. The old system only provides ATIS, AWOS and
some dialog lookups, and hence should not conflict with the new system.
This is an ugly hack for automatic runway selection on startup based on
metar data. It's main intention is to make startup.nas obsolete and
to guarantee the same runway selection logic as used for AI traffic.
Calling presets-commit from startup.nas during the initialization
sequence caused occasional trouble and sometimes, the AI traffic
operated on the opposite runway.
The autopilot has grown beyond being just an autopilot. It's
components, filters and controllers could be used to set property
values based on complex rules and driven from other property values.
That's why I chose to give it the name "property-rule".
This patch allows to define an arbitrary number of property rules under
a/sim/property-rule[n]/path
using the same syntax as autopilot configurations.
- Point the homedir variable to %APPDATA%/flightgear.org. This
enables .fgfsrc in this path for windows users.
- Evaluate the returncode of gethostname() to not strdup() bogus
characters on failure. Also mainly on windows.
Add helper to look for an aircraft branch path in multiple candidate locations.
Update the main subsystems to use the helper, and hence load from any aircraft dir.
Split the former single-file-implementation in xmlauto.?xx into multiple
files and use some OO techniques. Started with documentation to be used
with doxygen.
* AI aircraft distance to user proximity detection works again (lat/lon were inverted).
* The parking uses by the user aircraft is marked as such to prevent it being reused by an AI aicraft
* AI aircraft won't receive permission for pushback until the user aircraft is at a fair distance.
* Add a new command line option: --sound-device=""
This makes OpenAL use the sepcified audio device instead of the default
output device. (Look for playback devices when calling openal-info of alcinfo)
- allow multiple <autopilot> elements within an aircraft. All autopilot live in an individual FGXMLAutopilot subsystem which run within a subsystem group now.
8:: AWOS is available at AWOS locations. (Previously only ATIS was
implemented.)
9:: ATIS phraseology now more nearly conforms to international
standard METAR pattern, and therefore to usual FAA practice.(*)
Items marked with a (*) are fully implemented in the /text/ of the
ATIS message, but the voiced version of the message is degraded by
limitations of the FGFS built-in text-to-speech system.
10:: ATIS now reports sky condition.(*)
11:: ATIS now reports multiple layers of clouds, not just the lowest
layer.(*)
12:: ATIS now takes field elevation into account when calculating
sky condition and ceiling.
13:: ATIS now reports dewpoint.(*)
14:: ATIS now can handle negative quantities (temperature and dewpoint).(*)
15:: ATIS can now report report fractional-mile visibility.(*)
16:: ATIS now uses magnetic (not true) wind directions, as it should.
17:: ATIS generates correct runway number and suffix (nine right,
one one left).
18:: ATIS can be received on nav frequencies, not just comm.
19:: Nothing bad happens if the same ATIS is tuned up on more than
one receiver.
20:: ATIS can be updated at times other than at the top of the hour.
21:: ATIS listens for an "attention" signal, and responds to changes
in the weather by issuing a new ATIS message (somewhat like a
"special observation").
22:: ATIS volume now responds to radio volume setting.
23:: Area-related services (i.e. approach radar) are handled
more-nearly consistently with radio-frequency related services.
24:: ATIS sequence-letter generation has been fixed.
25:: ATIS messages are now in the property tree, so they can be read
e.g. via the http interface.
by frequency (which makes sense), and use the FGPositioned spatial data if
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
notably, all the 'airport-related' navaids (ILS, GS, LOC, and the beacons) now
store a FGRunway* instead of an airport id string. This is more precise, and
saves string allocations.
By way of example, here's a patch to make the position init code (in fg_init.cxx) cleaner, partly thanks to the FGPositioned changes. It reduces the file size by 200 lines - virtually all of which was copy-and-paste. Once the remaining class (FGAirport) is converted to inherit FGPositioned, all the future patches should be like this - touching one or a few files at most.
This factors the start-offset logic out into a helper, which also does the final property setting (which has to happen on both the /preset and 'real' values). Using the accessors in FGPositioned, and the offset helper, a couple of cases become trivial (fix and nav) and others become much simpler.
Convert FGNavRecord to inherit FGPositioned. This is much more self-contained than the FGRunway change, since FGNavRecord already had good encapsulation of its state. However, it's a large diff due to moving around two nasty pieces of code - the 'align navaid with extended runway centerline' logic and the 'penalise transmitters at the opposite runway end' logic.
In general things are more readable because I've replaced the Navaid type enum, and the use of Robin's integer type codes, with switches on the FGPositioned::Type code - no more trying to recall that '6' is an outer marker in Robin's data. The creation code path is also pushed down from navdb into navrecord itself.
Convert FGRunway to be heap-based, and inherit FGPositioned. This is a large, ugly change, since FGRunway was essentially a plain struct, with no accessors or abstraction. This change adds various helpers and accessors to FGRunway, but doesn't change many places to use them - that will be a follow up series of patches. It's still a large patch, but outside of FGAirport and FGRunway, mostly mechanical search-and-replace.
An interesting part of this change is that reciprocal runways now exist as independent objects, rather than being created on the fly by the search methods. This simplifies some pieces of code that search for and iterate runways. For users who only want one 'end' of a runway, the new 'isReciprocal' predicate allows them to ignore the 'other' end. Current the only user of this is the 'ground-radar' ATC feature. If we had data on which runways are truly 'single-ended', it would now be trivial to use this in the airport loader to *not* create the reciprocal.
Here's part 2 - converting FGFix (the simplest one) to be both heap-based and inherit FGPositioned. One minor benefit from this is replacing some dangerous code in FGFixList which used to return the address of an iterator member ('&it->second'). To keep the diff a sensible size, I'm not updating the callers to use the richer FGPositioned types - i.e replacing separate lat/lon handling with SGGeod. I will make those cleanups, but in future patches.
- Runways are now part of an airport, instead of a separate list
- Runways are no longer represented as a boring struct, but as a class
of their own.
-Improved runway access to unify various runway access methods.
* experimental clean-up / reduction on two of the FG headers:
(I'm going to await feedback on the developers list before doing more of
these, to avoiding going over files multiple times, but in principle it
seems pretty straightforward.)
* final fixes for SG_USING_STD removal
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
