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).
8:: AWOS is available at AWOS locations. (Previously only ATIS was
implemented.)
9:: ATIS phraseology now more nearly conforms to international
standard METAR pattern, and therefore to usual FAA practice.(*)
Items marked with a (*) are fully implemented in the /text/ of the
ATIS message, but the voiced version of the message is degraded by
limitations of the FGFS built-in text-to-speech system.
10:: ATIS now reports sky condition.(*)
11:: ATIS now reports multiple layers of clouds, not just the lowest
layer.(*)
12:: ATIS now takes field elevation into account when calculating
sky condition and ceiling.
13:: ATIS now reports dewpoint.(*)
14:: ATIS now can handle negative quantities (temperature and dewpoint).(*)
15:: ATIS can now report report fractional-mile visibility.(*)
16:: ATIS now uses magnetic (not true) wind directions, as it should.
17:: ATIS generates correct runway number and suffix (nine right,
one one left).
18:: ATIS can be received on nav frequencies, not just comm.
19:: Nothing bad happens if the same ATIS is tuned up on more than
one receiver.
20:: ATIS can be updated at times other than at the top of the hour.
21:: ATIS listens for an "attention" signal, and responds to changes
in the weather by issuing a new ATIS message (somewhat like a
"special observation").
22:: ATIS volume now responds to radio volume setting.
23:: Area-related services (i.e. approach radar) are handled
more-nearly consistently with radio-frequency related services.
24:: ATIS sequence-letter generation has been fixed.
25:: ATIS messages are now in the property tree, so they can be read
e.g. via the http interface.
- 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.
- 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)
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.
