I found that all the current users of the companion
function, findByFreq() actually did assume radians despite the misleading
comment in the .hxx and .cxx saying it's degrees. I've fixed the
comment now, and no longer change the Navaids code. The new Navaids user
in NewWaypoint() is now passing radians to the findByIdent().
Note that along with fixing the comments in the navlist.hxx, I removed
an obsolete method findByLoc() declaration (there is no definition
anywhere).
This adds a TACAN instrument to the inventory. Range and bearing are calculated
to the TACAN or VORTAC beacon selected by means of the Channel Selector in the E
quipment/Radio pull-down menu.
A TACAN beacon has also been added to the aircraft carrier Nimitz (channel #029Y
).
These change add some code that at initialization time will snap all
localizers into perfect alignment with their runways. It's my experience
that the DAFIF/FAA data reports runway and localizer headings to a level
of precision that is great for making charts, or adjusting your OBS, etc.
But the level of precision of this data can be far enough off to make you
visibly *un*aligned with the runway when the CDI needle is centered.
There are probably cases where the localizer isn't really perfectly
aligned with the runway, or intentionally misaligned to avoid obstacles
or terrain. So I have made this configurable for those that trust the
data more than I do. Just set "/sim/navdb/auto-align-localizers" to
true/false in the preferences file to turn this feature on or off in the
code.
- FG now directly supports Robin's native nav database file format.
- His latest data now separates out dme, gs, loc, and marker beacon
transmitters rather than lumping them all into a single "ILS" record.
- These new data structure changes prompted me to do some code restructuring
so that internally these different types of navaids are all kept as
separate lists and searched and handled separately.
- This structural change had a cascading affect on any code that
references or uses the nav databases. I've gone and "touched" a lot of
nav related code in a lot of places.
- As an added bonus, the new data (and code) adds DME bias so these will
all now read as they do in real life.
- Added Navaids/navdb.cxx and Navaids/navdb.hxx which provide a front
end loaders for the nav data.
- Added Navaids/navrecord.hxx which is a new "generic" nav data record.
- Removed Navaids/ils.hxx, Navaids/ilslist.cxx, Navaids/ilslist.hxx,
Navaids/mkrbeacons.cxx, and Navaids/mkrbeacons.hxx which are all now
depricated.
if the station is too far away. Instead, simply return the closest station.
All the code that searches navaids does it's own range checking anyway.
This will make the navlist query functions a bit more useful for other
types of functionality where you may need to lookup a station without
consideration of range (i.e. presetting your position relative to a navaid.)
Modifications to support querying navaid database by station ID (not just
frequency.) Some corresponding changes to testnavs.cxx to test new
functionality.
