- when add-noise is false, mute noise completely
- if the CommRadio is not powered by the generic electrical system,
work by default (as was previously the case)
Using Emesary Global Transmitter the following events are notified
* Frame Begin
* Frame End
* Mainloop started
* Mainloop stopped
This integrates with the background threaded Nasal Garbage collection (simgear:nasal/cppbind/NasalEmesaryInterface.hxx) and is also controlled by the properties as follows
* /sim/nasal-gc-threaded (true) - use background threaded GC
* /sim/nasal-gc-threaded-wait (false) - at the start of the frame wait for the previous GC thread to complete.
I initially thought that the wait at the start of the frame would be necessary; however in 100 or so hours of flight without the await for completion at the start of frame no threading problems (or any other problems) were shown; so nasal-gc-threaded-wait is defaulted to false which gives a slight boost in performance.
So what this does is to it removes the GC pause of 10-20ms every 4 seconds (test using the F-15). This change doesn't really give much extra performance per frame because normally GC is only performed when needed.
Neither Torsten nor I can recall why we continued to hard-code this,
so make it dynamic for now. When we remember why we hard-code it,
we can add a BigComment from future-James to future-future-James about
why not to do this again :)
Due to e43fe82094 models in AI scenarios were
being searched down the AI/Aircraft and Aircraft paths, where in fact
they are by default a full path from FGDATA.
This fixes the problem by setting DATA_ONLY as the search order.
Other search orders can be set in the scenario file by setting
the search-order tag to "DATA_ONLY", "PREFER_AI", "PREFER_DATA"
Based on the dew point temperature supplied by FG, JSBSim updates the atmosphere density and computes all the usual parameters (RH, vapor pressure, saturated vapor pressure, etc.)
The mass fraction of water per unit of air mass is capped according to the record high from ISA 1976 standard atmosphere. As a consequence, at very high altitudes, air is always extremely dry (approx. 30 ppm i.e. 30 parts per million) whatever the conditions at sea level.

Previously, selecting a non-pushback parking position from the l
auncher that did not have a ground network resulted in the
aircraft being placed in the center of the airport.
This resolves the problem by creating a default segment simply
moving forward 2m.
Since PLIBjs uses joyGetDevCaps()[1] on Windows and this function
accepts joystick ids from 0 to 15 (-1 being special), setting
MAX_JOYSTICKS to 16 ensures that FGJoystickInput::init() can scan all
joysticks that joyGetDevCaps() is able to report about.
