Iterator must be reset after clearing waypoint list.
Deleting "*waypoint.end()" doesn't delete the last waypoint (end()-1
does - it is never actually used though).
Make landings and takeoffs look more correct; tweak climb-out and touchdown phases in particular, so the turn to destination heading occurs earlier on climb out, and touchdown occurs close the GS transmitter / some distance down the runway from the beginning.
distance_to_go / lead_distance were not initialized in all constructors.
Fixes 'condition on uninitialized data' reported by valgrind.
Also comment-out unused vars.
* Pregenerating taxiroutes could interfere with runway assignments by ATC, when conditions changed, resulting in a taxi to one runway and a takeoff from another
* A simpler solution for the "Error in Traffic record bug". This still needs some more testing, but I haven't seen any error message anymore, since changing to the current code.
* Initialize AI traffic at speed zero, this should prevent some weirdness observed under boundary conditions.
* Don't activate groundnetwork proximity detection for pushback traffic until the "ready for startup message is transmitted. this should allow sufficient time for them to reserve a route, but a little more testing still needs to be done.
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
* Landing AIAircraft now land properly!!!
* Fixed problems with takeoff scheduling.
* Untangled several vertical speed calculation algorithms.
* No more bent-over-backwards and jump-in-the-air AI aircraft initializations.
* Fixed intermixed target speed and target altitude during climb phase.
* Implemented beginnings of a "line up and wait" procedure.
* Tried to use actual runway elevation for calculating the decent profile.
- Better transistion between taxi and takeoff phases.
- Skipping the pushback stages when a gate doesn't require push-back.
- Some test code always chooses the user aircraft as the one that has to hold position.
- Change AIFlightPlan::waypoint into an independent class FGAIWaypoint
- Don't update leg count until the aircraft has passed the last waypoint that was created by the corresponding leg
- Clear ground network rendering for controllers that are no longer active.
- Fixed a bug in AI aircraft ground steering code: When aircraft were not moving, the value of headingchangeRate kept increasing to insane levels. Although this was clamped to a maximum of 30 degrees per second, the initial rate could still push the aircraft in the wrong direction. In practice, this bug would be visible when an AI aicraft would be pushed back, when it tended to veer to the right.
- Make sure that the aircraft slows down well ahead of the pushback point. This change ensures that the AC will actually reach the pushback point. It also ensures a slightly tighter steering range.
- AI ground steering rate is tuned to 30 degrees per second at a nominal taxispeed of 15. I now modulate the heading adjustment rate by manipulating the adjustment using a non-linear function (the sqrt). This allows for a slightly tighter turn radius at speeds < 15 and slightly looser turns at speeds > 15.
- The AI Flightplan generation code can return false. This can be used to determine whether any additional AI aircraft may be created. Currently, the function returns false when no more parkings are available. This should limit the build-up of huge AIAircraft tower stacks.
- The ground network can now graphically display all aircraft actitivy on the ground network by using a virtual marker system.
* New features
- More realistic descent paths
- Separation during descent and approach
- ATC approach controller (still silent)
- inbound traffic flow will start immediately
* Bug fixes
- Properly handle vertical speed when on ground
- Departing aircraft now wait for taxiclerance before moving
- Traffic manager waits for proper weather initialization
- Fixed instabilities in the preferential runway usage code
- Fine tuning of waypoint following code.
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.
* 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.
* 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.
- 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.
PLETE_FUNCTIONAL from SimGear and FlightGear.
As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.
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.

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.
work for ground based distance separation of AIAircraft.
Traffic manager initialization related changes:
- Schedules initialize "on the fly", instead of during initialization
- Invalid routes are no longer deleted, but marked as BOGUS and ignored
- Changed loading order from a distance based prioritization to a point-
score based prioritization, resulting in a much faster establisment of
AIAircraft near the user's plane.
Preparatory work for ground-based separation of Aircraft.
- The groundnetwork findShrortestRoute function not only returns a list
of waypoints, but also a list of taxi "segments" (a.k.a. taxiways).
- The taxiway list is stored in the Flightplan, and updated everytime
a new taxi leg is created.
