- Calculate line of sight distance instead of distance over
ground
- Do a nav cache update if carrier_nav.dat.gz timestamp has
changed
- Allow comments in carrier_nav.dat.gz
- "Fix" range calculations (still does not take terrain/weather
and other influences into account)
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
In preparation for adding POI data, extend the FGPositioned type enum, and the cache code to handle arbitrary POI types. (Adding more in the future is straightforward now)
Also support removing user waypoints, which was requested by the Garmin G196 developers.
At large search ranges (320 or 640NM range on the 777), the search time can blow up, especially if distant airports are being loaded. Add a time-bounded spatial query, and use it, so performance stays tolerable.
As an opt-in API, allow clients to request partial results, with a time-bounded cutoff. Use this to keep the MapWidget responsive even when many airports are being added to the cache (e.g., zooming out or panning rapidly when zoomed out)
When a position is modified for an in-cache FGPositioned, we need to update the runtime information too, or the Octree code may (rightly) complain that it's seeing inconsistent data. Also make the Octree check an exception throw, and verbose, so this is easier to detect in the future.
In preparation for caching the groundnet in the NavCache, make taxi-nodes and parkings inherit from FGPositioned. As part of this, make them heap (as opposed to value) classes, disable their copy-constructors, remove many mutating operations, and give them real constructors.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
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.
const) which were previously tricky but now easy. Make it possible not to
index certain types (used for taxiways) and exclude anonymous items from
the name index. Related to this, clean up FGRunway further - remove some public
members, and fix a dumb bug of mine, where we create reciprocal entries for
taxiways.
This should make startup (slightly) quicker, and shrinks FGRunway somewhat.
- updates how filtering is done on the various FGPositioned query functions - both spatial and ident-based.
- updates the KLN-89b / DCLGPS code to use FGPositioned for all Navaid/Airport queries.

Add few include directives in globals.cxx to avoid such MSVC warning messages :
deletion of pointer to incomplete type 'FGAirportList'; no destructor called
deletion of pointer to incomplete type 'FGNavList'; no destructor called
deletion of pointer to incomplete type 'FGTACANList'; no destructor called
deletion of pointer to incomplete type 'FGFixList'; no destructor called
