Attempting to fix Sentry crash FLIGHTGEAR-B, crash on shutdown. Not
sure this is quite right, but the logic is clearer and we handle
invalid iterators better.
* 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- Clear ground network rendering for controllers that are no longer active.
* Allow position and intentions to be monitored and updated by the Startup controller
* Added a "parent" pointer to the startup controller to allow communication with the groundnetwork.
* Implemented a render() function for the Startup controller
* Renamed "FGGroundNetwork::getRenderNode() to FGGroundnetwork::render()
- 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.
* 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.
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. :-).
- 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
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
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
