Background are problems modeling the rotax 912 engine. The idle speed
of the real engine is about half of the speed I could achieve with the
default minimum manifold pressure. While on ground I can switch off
the engine by pulling the throttle. The audible difference between the
different minimum idle speed (real vs. simulated) is extreme. With the
patch I get quite realistic sound. For the rotax engine I use
min-throttle="0.05" which is half of the former default value.
localtime() is once commented out in simgear/io/sg_binobj.cxx and
a warning says the it can screw up sim time. This is only because
localtime() isn't thread-safe (and its thread-safe cousin localtime_r()
isn't portable). As long as all timing is done in the main thread
(which is the case) there should be no problem. Otherwise we'd have
to implement a simple mutex locked wrapper.
* Changed the runway XX. ATC message to actually report the real
designated departure runway
* In case of multiple active runways, select the one with a heading that is
closest to the direction of the ultimate departure destination / lines up
with the arrival path.
This gets rid of a lot of messy code. Although the performance is about
the same as the old code, there is the possibility of a big performance
boost if/when the polytope intersector is taught about KD trees.
- make some char* "const" to silence warnings
This removes the warning that (rarely) occurred if one wrote to a
write protected property with setprop(). While this was a useful
hint, it needlessly floods the terminal if one protected a property
intentionally. (Consider to add an SG_DEBUG warning instead.) It's
now the caller's job to check for the result if it actually cares.
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. :-).
In multiplaymgr.cxx:
The length of a string property that is too big was written out in the message
even though the string was truncated. Also, it was possible to overrun the
message buffer.
In incoming messages, null-terminate the callsign to prevent any funny
business. Don't believe invalid string lengths. Turn the warning about unknown
properties from a warning into info; there are too many buggy clients out there,
not to mention people who add their own MP properties (hi vivian :)
