This patch changes terrasync so it links against the subversion
library if you have it installed. It supports people who build binary
releases for use by non-developers by removing the runtime external
dependency on having command line svn or rsync available. Since the
patch changes autoconf to detect libsvn, I'd appreciate it if people
who release binaries could verify that the detection scripting works
for their platform.
Developer warning: If you do have libsvn developer libraries
installed, terrasync changes its default option from "-R" to "-S" to
remove the command line dependency. However, Martin has not yet
uploaded world scenery into the subversion repository so it won't be
useful to fly against and you may want to specify "-R" on the command
line in the short term. Or run both.

- 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.
- 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
Various other patches that have been lingering around for a while:
* Moved trafficcontrol.[ch]xx from the Airports directory to ATC, where
it really belongs.
* AI aircraft will request startup clearance, and ground control will
approve.
* Starting AI Aircraft will be pushed back to a predefined holding point
on the ground network, and wait a while before taxiing out to the runway
and the pushback code:
- Traffic manager starts modelload requests immediately upon program
loading
- Only create legs 1 (push back) or five (cruise) of AI traffic.
- AIAircraft's rather obsessive behavior to circle around a waypoint is
largely resolved
- More realistic ground steering for AI aircraft.
and "isOnRunway".
- Added initial support for AI controlled pushback operations, making use of the
current editing capabilities of TaxiDraw CVS / New_GUI_CODE. The current
implementation is slightly more computationally intensive than strictly
required, due to the currently inability of taxidraw to link one specific
pushBack point to to a particular startup location. FlightGear now determines
this dynamically, and once we have that functionality in TaxiDraw, the
initialization part of createPushBack() can be further simplified.
- Smoother transition from pushback to taxi. No more skipping of waypoints, and
aircraft wait for two minutes at pushback point.
- The classes FGTaxiNode, FGTaxiSegment, and FGParking, now have copy
constructors, and assignment operators.
- Removed declaration of undefined constructor FGTaxiNode(double, double, int)
- Array boundry checks and cleanup.
- Modified Dijkstra path search algoritm to solve partial problems. Currently
limited to include pushback points and routes only, but can probably be
extended to a more general approach.
- Added initial support for giving certain routes in the network a penalty, in
order to discourage the use of certain routes over others.
- Airports Directory
Thomas Foerster: Pulls out the FGTaxiNode implementation into gnnode.cxx.
Melchior / Durk: Copy Constructor and assignment operator for FGTaxiRoute

Durk / Melchior / Czaba Halasz: Ensure that all derived classes use AIBase
member 'callsign'. Adapted, moved and deleted getter/setter functions where
necessary

DT: Temporary revert parts of the position estimation code.

2) Decrease AI aircraft Heading error tolerance to 1% of its
original value. This is necessary to mitigate spinning and
makes for actual "on-runway" landings.
data for AI traffic. Default performance classes are still available as a
backup. This database will allow the calculation of aircraft-specific
take-off speed and estimate runway lenght requirements. Further added
rudimentary support for take-off and landing rotation of AIAircraft.
Here is a patch for two bugs in the AI/multiplayer part:
1. Cannot find model file *.ac error message (was only a false message,
anything worked correctly, the model was loaded from the correct path
afterwards).
2. Often many multiplayer aircrafts are missing in the property-tree.
(but I need them for aerotowing). There is still another bug: The
property in some circumstances seems not to be cleaned up after logout
of a multiplayer. I have added a workaround for this, but I don't now,
if it 100% works (should have no side effects, just aerotow would not
work sometimes). For testing I need more traffic on the mp-server.
- Ground network slow-down finally works as expected
(although occasionally causing a traffic jam)
- Hold position instruction now really sets speed to zero, in addition
it actually works now for crossing and two-way traffic
- Attempt to limit execution time of ground network trace algorithm
to make performance acceptable at high-density networks
- Removed remaining terminal messages
- Various minor tweaks and clean-ups
- Moved AIModels/Traffic Manager related AI functions to a new file
- Rewrote the traffic manager so that the containers use pointers to
objects instead of the objects themselves, which will allow for a
more flexible memory management.
- Rewrote parts of the airport groundnetwork code, also because the
stl containers now contain object pointers instead of the objects
themselves.
- Fixed an uninitialized iterator in the AI distance tracking code
- Fixed flawed logic in some of the traffic controller's while loops
- Added a tower controller, which paces take-off behavior of AITraffic
in a more realistic way.
- Various other minor fixes and fine tuning.
maintain a resonable distance from each other while taxiing on the same
route. The current code does not yet take crossing routes or aircraft
taxiing into opposite directions into account.
using Curt's new speed adjustment code. 2) Separated the function
FlightPlanCreateCruise() into a new source file in preparation of a more
elaborate airway following scheme.
and tgt_altitude -> tgt_altitude_ft. Also fix a comment in AIBase.hxx
indicating that the altitude is in meters, even though the usage throughout the
code was most definitely feet.
- In AIMultiplayer.cxx, update the altitude_ft variable so that the altitude
is reported correctly in the entity's property subtree.
- In AIMultiplayer.cxx, compute a velocity value in kts to fill in the speed
entry in the entity's property subtree. Note, this is not an earth centered
reference speed, not an indicated speed and not a speed relative to the local
airmass (that would be much harder to do.)
flightplan. Such aircraft are given some initial conditions that they
fly with. They proceed on in "freeflight" mode indefinitely. For example,
there is a refueling demo where the tanker starts at 3000', 280 kts, and
in a 15 degree bank, and then continues to orbit indefinitely.
For these aircraft with no flightplan, I have added several control nodes in
controls/flight that allow a script or menu or external application to set
heading, altitude, bank angle, and speed. This permits some level of interactive
or scripted control over AI aircraft.

"Bug Fix - amend the code so that JSBSIm can have more than one tanker in
the environment at the same time. A nasal script has to be added to each
aar-capable JSBSim model to complete this fix."
"Preparations for an upgrade to Air-to-Air Refuelling to allow more than one
tanker in the environment at a time. This will only work with YASim models.
JSBSim models are unaffected by this change."
"Add Air to Air TACAN. With this facility TACAN equipped aircraft can
measure the range and bearing of TACAN equipped AI Aircraft. ATM there is
only one assigned - callsign ESSO1 on TACAN channel 039X, but this can be
easily expanded to include other c/s channel # pairs - just ask me if you
want more."
When AIFlightPlanCreateTaxi() function is called with the firstFlight
argument set to true, this is supposed to handle situations where the
the aircraft's timetable indicates it should have left between about 5 to
20 minutes earlier. In the previous version, all these aircraft started
taxiing from the first parking location available in the network, due
to the fact that the variable gateId was not assigned a value. In this
patch, route tracing starts from an assigned gate and the network node
following code is fast forwarded to a random location along the taxiways
to give a more realistic and natural distribution of taxiing aircraft
after startup.
This patch further addresses some weird ballet-dancing behavior that
aircraft were showing just prior to/right after parking and which was
related to a number of more or less duplicate waypoints in the transition
from createTaxi() to createParking() to createPushBack() to createTaxi().
Finally, a blatant typing error in the getParking() function was fixed.
at (lon, lat) coordinates -1000,0. This patch fixes the AIModels/Traffic
Manager side of things. The AIModels subsystems allowed the creation of
AIAircraft with non-existent 3D models. If such a model didn't exist, the
aip class didn't get initialized, resulting in the above-mentioned bogus
position information. Here I circumvent this problem by a) only interacting
with the tile loader if the model is visible (and hence has succesfully been
initialized) and b) by disallowing the traffic manager to create AIAircraft
objects if the path to the 3D model doesn't exist.
This patch removes some useless indirection when creating AIModels. It
obsolets AIScenario*.
AIEntities are just an intermediate copy of an other intermediate copy of an
xml file on the way from the ai scenario configuration file to the AIModels.
As such the AImodels can now be created directly from the property tree read
from the scenario file.
This reduces the amount of work needed to add an other AIModel and reduces the
amount of copy operations done during initialization.
It also moves internal knowledge of special AI models into these special AI
models class instead of spreading that into the whole AIModel subdirectory
which in turn enables to use carrier internal data structures for carrier
internal data ...
Also some unused variables are removed from the AIModel classes.
I believe that there are still more of them, but that is what I stumbled
accross ...
Tested, like the other splitouts these days in a seperate tree and using the
autopilot for some time, and in this case with a carrier start ...
- Feet to meter conversion mistake (in AI getGround elev)
- Improved ground following code (not yet perfect, but for now no one will
notice it within the marginal altitiude differences at the taxitrack or
runway)
- Exclusion of the "AI" directory witihin data/Aircraft in
main/init/fgSearchAircraft, to prevent AI aircraft to be picked up by the
aircraft search function
I have prepared a patch that:
- Introduces a FGTileMgr::scenery_available method which asks the tilemanager
if scenery for a given range around a lat/lon pair is already loaded and make
use of that method at some -9999 meter checks.
- Introduces a FGScenery::get_elevation_m method which queries the altitude at
a given position. In constrast to the groundcache functions this is the best
choice if you ask for one *single* altitude value. Make use of that thing in
AI/ATC classes and for the current views ground level. At the current views
part the groundcache is reused if possible.
- The computation of the 'current groundlevel' is no longer done on the
tilemanagers update since the required functions are now better seperated.
Alltogether it eliminates somehow redundant terrain level computations which
are now superseeded by that more finegrained functions and the existence of
the groundcache. Additionally it introduces an api to commonly required
functions which was very complex to do prevously.
I added an AIStatic object to my OV-10 sim for use in putting city signs,
vehicles, or anything else that will be static, but that I don't want to put
in the scenery files. It's inexpensive. Before, I was making such things
from AIShip.
I also added the ability to set flight plans to repeat, so that when an
airplane reaches the end it just starts over at the beginning. This is
useful for my OV-10 sim. I have C-141 and KC-135 traffic flying approaches
to Ramstein, and I only have to define two AI objects to do this.
Also, I found an inefficiency in AIBase, where every AI object was calculating
Mach number at every dt. Now only AIBallistic objects do this.
