The following patches to SimGear & FlightGear ...
- create an FGMetar abstraction layer, whose purpose is:
* provide defaults for unset values
* interpolate/randomize data (GREATER_THAN)
* derive additional values (time, age, snow cover)
* consider minimum identifier (CAVOK, mil. color codes)
- add rain/hail/snow/snowcover support on the METAR side
- add max age of METAR data handling (currently set to
- add support for an external METAR cache proxy server
- add CAVOK handling
- set missing year/month in regular METAR messages
- fix a small bug in metar.cxx (wrong return value)
rather than /instrumentation/comm ... we need to be a little careful here
because typically, a single knob controls power to both matched com/nav pairs.
explicit calls to shutdown_all() which was causing this to be called twice.
This could cause problems with some IO modules (such as attempting to close
an invalid file descriptor the second time.)
a seperate explicite call or the io channels will be forced to try to shutdown
twice which could cause problems for some IO modules (i.e. attempting to
close an invalid file descriptor the second time ...)
We should now be able to find
wires or catapults when the ac3d model is loaded without the crease patch
(caused by the much more unstructured scene graph emitted by the old loader).
It should also emit more warnings if the carrier hardware configuration
includes conflicting definitions.
That code is the most intrusive one, it should not be used until you configure
an aircraft carrier as a aimodel. So I think it should be save to apply that
before the release too.
Attached is a patched runways.cxx. This fixes the find runway nearest to a given heading code. This was returning the last runway loaded at a given airport, not the nearest runway to the heading requested (which seems to always be 270deg by default). I have no idea how this has survived unnoticed for so long - I think it might be because you need to start at an airport with a runway near to 27 and one much greater than 27 eg. 36 to really tickle it, otherwise the runway nearest to 27 tends to be the final one loaded anyway. Try starting at KARR with and without the patch and note the surface wind. This should go in before the release.
a single apt.dat.gz file which is in the native X-Plane format.
To do this I wrote a front end loader than builds the airport and runway
list. Some of the changes I needed to make had a cascading effect, so there
are minor naming changes scattered throughout the code.
