rwyprefs.xml sometimes specify runways without a leading '0', which
confuses the ident lookup. Print a message, and fix up such idents at
load time, so '8' -> '08', '3L' -> '03L' which matches our internal
scheme.
* 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.
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.
- 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.
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
own preferential runway support. In future versions, we might want to
condider having a more generic mechanism for this.
- Keep a history of active runway for each class, so that runway assignments
are more consistent after whether updates or time-related schedule changes.
I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a
facade to the loader functions. Further I changed FGRunwayPreference to just
keep a FGAirport ref, which is more concise and closer to the right(tm)
solution than storing the airport data a second time ;-)
- 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
The original code selected the most preferable runway combination,
regardless of which combination was currently active. This patch
builds in some additional resistance against change, by keeping
track of which runways are already in use, and forces a change
in active runways only when new (wheather/time of day) conditions
force it to do so, resulting in much more consistent runway assignment.
behavior.
