For 2.12, ensure all GPS instruments are backwards
compatible, however they were requested. Post release we can create a new instrument name with the compatibility code disabled.
There's a sufficiently large installed base, that simply dropping this
API is not acceptable. A Nasal shim might be possible, but in the
interim, restore the C++ functionality.
Generic transponder can emulate KT-70 props. These emulated props
will likely die in the future, based on feedback from aircraft devs.
See (upcoming) Wiki docs on the transponder for more info.
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.

This allows delegates to take action when the flightlan is cleared, and especially, for the default delegate in the route-manager to deactivate itself, and hence the GPS LEG mode - which fixes bug 940 I hope.
One of the two route termination conditions was improperly handled, leading to bad leg/wpt indices and exceptions from the GPS code. Detect passing the final waypoint in a more robust way now.
Also fix the GPS code to avoid turn computation on the final leg.
Don't show invalid AI/MP models in the HUD (after they were removed from
the scene).
Also, when a radar is installed, consider radar/in-range for HUD display.
Error/offset induced by precession and yaw also depend on spin (no spin =>
no additional error/offset).
Error/offset induced by changing a/c orientation while gyro spin is
low (<<1) should apply to the "offset" (instead of "error") property.
An upcoming commit will make the sound headers standalone, and no longer include various other headers / using std:: declarations. Prepare for this by making includes and usage of namespaces explicit.
- Only render the canvas if something has actually changed
(Currently checked by looking for modified properties).
- Only write bounding box to property tree if it has been
recalculated (until now this happened every frame).
Low spin or switched off gyros result in the indicator being stuck.
When the gyros are repowered, the indication doesn't jump to the correct
indication, but keeps the current error.
so they can instantly adjust to the changed environment.
(Not fully working yet, since some environment settings, like environemnt
pressure/temperature, still changes slowly after a sim reset - instead of
immediately jumping to the new setting. Also, METAR sometimes arrives too
late...).
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).
Various classes derive from SubsystemGroup, but extend the init behaviour. Fix those for the incremental init scheme, generally by forcing their init to be atomic. Can convert them to be truly incremental in the future if it's needed, but probably not.
Remove various hacks and make magvar work like a normal subsystem, as part of the environment manager. Fix the remaining users of the globals->get_mag accessor, and hence kill off the global pointer.
- Refactor CanvasMgr into PropertyBasedMgr to be also used
for the Canvas GUI system.
- Get rid of tied properties in the Canvas system.
- Add new placement type 'window' for placing canvases onto
windows
- Pass mouse events to Window class (only if cursor is over
window)
- Refactor canvas placement clean up
- Allow hiding objects
- Use UTF-8 encoding for text elements
- Add paramter max-width to text elements
- Support stroke-linecap for path elements
- Fix mouse coords
- Set better mipmap filter
Add same property as for nav radio, to provide a property to cockpit models
whether the ADF is active (serviceable/switched on/power ok/...). Useful
to enable/disable displays (i.e. KR87).
The glideslope station was only searched once whenever the NAV station
changed. However, sometimes a mismatching G/S station is found, since
another G/S station is still closer when the NAV station changes.
When this happened, the G/S station was never updated again (while the
NAV station stayed in range), resulting in the NAV receiver providing
correct localizer, but bad G/S data (data matching another, remote station).
Issue is fixed by alternating between searching NAV and G/S stations.
Make sure gs-inrange and deflection outputs have same behaviour, no matter
which out-of-range condition applies (i.e. aircraft moved out of range,
frequency changed, ...).
- Support text-enable condition on symbols
- support <limit>N</limit> on symbols to restrict
to closest N symbol instances.
- change search to hopefully be more stable at
larger ranges.
Convert the route-manager to use a flight-plan internally, and expose
flightplan, leg and procedure data to Nasal. Move the Level-D parser
into its own file.
Aircraft could fall through the ground on scenery reload. Properly reset
the "sceneryloaded" flag to pause FDM processing while scenery is being
reloaded. Also stop processing some instruments while scenery is reloaded.
This property is true if the active frequency is tuned to a
paired LOC/GS frequency in the range 108.00 - 111.95 with a
odd 100kHz digit (108.10, 108.15, 108.30, 108.35 ...)
It only indicates, that this _is_ a LOC/GS frequency,
it does _not_ provide any indication if a LOC/GS station is
actually being received.
Don't initialize the offset in the main loop but in
the init method of the implementing class. This ensures
it gets initialized if you instantiate more than one
heading-indicator and does not initialize the property for
unsused heading-indicators (no more stray heading-indicator-fg
property anymore).
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
Avoid frequently creating/dropping an identical sound sample, when the
nav radio signal is flickering. Always keep most recent sound when signal
is lost (only stop it/turn volume off).
Our nav.dat.gz seem to have many bugs regarding paired LOC/DME where
the DME is missing.
A feature has recently been introduced to always use a LOC frequency
as a DME to avoid these issues. However many LOC station do not have
a DME paired at their frequency and this behaviour might be as confusing
as having no DME where one should be.
Before we get new/bugfree navdata, a property can be set to select
the desired behaviour:
if /sim/realism/dme-fallback-to-loc is true or absent, LOC will be
treated as DME (realism is off)
if /sim/realism/dme-fallback-to-loc is false, LOC will be NOT be
treated as DME (realism is on)
Here comes the work-in-progres code for a new navradio
implementation. Once completed, it will replace the
old/current navradio implementation.
The new code can be activated by setting
/instrumentation/use-new-navradio=true
at startup. This disables the old navradio implementation.
Current state:
- VOR works pretty good including the new
functionality 'code of confusion'.
- LOC and GS basically work
- backward compatibility (many properties) is to be implemented
- wrap the ident-generating code into a class
- move dme-in-range property into dme.cxx
- move dme-ident generation into dme.cxx
- support ident-button and volume for dme idents
- use globals.get_aircraft_position instead of properties
- some minor cleanup
When no navaid is found, '_ref_navaid_id_node->setStringValue("")' results
in a listener firing, which requests another navaid update when no navaid
is available.
=> Resulted in FGPositioned::findClosest being called in every update loop,
when no navaid was within range.
Whenever resolving a (relative) path to an absolute path with
'resolve_maybe_aircraft_path', check if the result is empty and report original
(relative) path as missing. Otherwise no or a meaningless message is
issued ("File '' not found.").
Fixes an ugly issue with OSG overwriting memory/stack. wxradar triggered
the issue in display mode "ARC" - since it configured a display mask (12
vertices) but all vertices were immediately removed again ("_vertices->clear()").
Issue is fixed, mask now working - however the mask wasn't even properly
aligned for the display (probably never worked since OSG port). The display
mask is only really required for weather display - so disabling for now.
This class and their source files visual_enviro.[h|c]xx were
unused since OSG transition. It's only functionality was to
keep a variable for the enable-state of rendering of precipitation.
This has now been moved to SGPrecipitation.
This patch also removes all references to this class and
visual_enviro.hxx. Wxradar needs a new implementation for cloud
echoes which probably should be part of fgclouds.

New "auto-position" switch to always use closest tower for tower-view.
Exposes new "/sim/airport/closest-airport-id" property.
Display closest airport on groundradar by default.
Property "dme-in-range" should also work with ILS signals, which include
a DME. The nav database (dme_list) doesn't have separate entries for
"ILS-DME" (unlike for "VOR-DME"), so searching a DME by frequency didn't
work for ILS.
=> "instrumentation/nav[*]/dme-in-range" can now be used to enable/disable
cockpit DME displays.
- former mk-viii voiceplayer is now an independent FGVoicePlayer
- voiceplayer still sits in mk-viii module for now
- add option to configure location/prefix of voice samples
- add pause/resume to voiceplayer
ADF bug fixes from John Denker. Changes from current behaviour are:
* Include the power button in the electrical checks
* Raise the required input voltage from 1V to 8V
* Don't reset the heading to 90 degrees when out of range or no power
(heading is now only reset to 90 in ANT or TEST mode)

This patch removes the conditional compilation of ATCDCL, compiling both
the old and new ATC systems. The old system only provides ATIS, AWOS and
some dialog lookups, and hence should not conflict with the new system.
Allow switching off slaved-to-gps (resynch NAV radio/update all NAV outputs)
Allow tuning NAV stations and keep DME alive when slaved to GPS
Clear station ID and heading when loosing NAV signal
Uninitialized variables were sources for NaN values.
Once NaNs are passed to Nasal (through (tied) properties), these cause
a crash. Nasal cannot handle NaNs - it interprets these as pointer values...
To load approach data into the KLN89, drop an ARINC 424 format file
named "rnav.dat" into the data/Navaids directory. The loader has
been tested on the 424-18 data revision, so may need tweaking for
the latest data. Currently about 97% of the listed US non-precision
approaches are loaded, the majority of the failures appear to be due
to 1-digit runway code offsets between the flightgear airport data
and the ARINC data due to magnetic variation changes.
