This fixes at least the startup process.
If an ambigous fix name was presented with --vor=ID or --ndb=ID
present a list of matching records along with frequency and
position in the console to give the user the chance to pick
the correct one by adding the frequency with --vor-frequency=nnn.nn
It does not yes solve the issue when the user relocates using the
GUI dialog. This requires some GUI and Nasal hacking along with a
new Nasal helper function "navaidinfo".
by frequency (which makes sense), and use the FGPositioned spatial data if
required. As a result, the marker beacon list is gone (since beacons are only
searched spatially). In the process, clean up various minor things - most
notably, all the 'airport-related' navaids (ILS, GS, LOC, and the beacons) now
store a FGRunway* instead of an airport id string. This is more precise, and
saves string allocations.
const) which were previously tricky but now easy. Make it possible not to
index certain types (used for taxiways) and exclude anonymous items from
the name index. Related to this, clean up FGRunway further - remove some public
members, and fix a dumb bug of mine, where we create reciprocal entries for
taxiways.
This should make startup (slightly) quicker, and shrinks FGRunway somewhat.
Convert FGNavRecord to inherit FGPositioned. This is much more self-contained than the FGRunway change, since FGNavRecord already had good encapsulation of its state. However, it's a large diff due to moving around two nasty pieces of code - the 'align navaid with extended runway centerline' logic and the 'penalise transmitters at the opposite runway end' logic.
In general things are more readable because I've replaced the Navaid type enum, and the use of Robin's integer type codes, with switches on the FGPositioned::Type code - no more trying to recall that '6' is an outer marker in Robin's data. The creation code path is also pushed down from navdb into navrecord itself.
version
* Delete ai list objects in ~ATC/AIMgr.cxx:AIMgr::~AIMgr()
* Delete colors in GUI/new_gui.cxx: NewGui::~NewGui.cxx
* Delete memory allocated to the class member "route" in
Instrumentation/gps.cxx
* Delete all globals (except a few "unsafe" ones that still cause segfaults
and need further examination.
* Use an SGShared pointer for navaid memory allocation, so that pointers to
individual navaid objects can be included safely in multiple navaid lists
I tried to make sure accessor functions which return by reference act
on const objects. also replaced some iterators with const_iterator
and a few return/pass by reference that were missed the first time
around.
* Use "const string&" rather than "string" in function calls when appropriate.
* Use "const Point3D&" instead of "Pint3D" in function calls when appropriate.
* Improved course calculation in calc_gc_course_dist()
* Safer thread handling code.
Vassilii Khachaturov:
Dont use "const Point3D&" for return types unless you're absolutely sure.
Erik Hofman:
* Use SGD_(2)PI(_[24]) as defined in simgear/constants.h rather than
calculating it by hand every time.
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
).
for localizers. I further hacked this to support GS and DME transmitters
(although Robin's DME transmitter data doesn't convey orientation
unfortunately.)
- 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.
My last patch fixed the initialization problem only for the main branch, but
ignored the _MWERKS_ branch.
- merged the branches, only the loop head needs different treatment;
- don't access n.type before it is initialized (valgrind complaint)
- created a constructor; the operator>> wouldn't have initialized all
variables in case of a broken default.nav.gz entry, so we would have
got a mixture of the broken one and the previous one; in case of
the first entry, that would have made nice random values ... ;-)
- move the automatic FGNav variable into the loop, so that the gets
cleanly constructed for every database entry.
- commented out the frequency min/max exploration, which isn't used at all
- updated the commented out debug output statements, which were simply
copied over from the nav* files, but never adapted (I needed them :-)
When the loop starts, n.type is still undefined, so the while statement
depends on unitialized garbage. The input operator cares for the [End]
bracket anyway (returns if the first character is a '['). So it is safe
to check for it after reading the line and break if necessary.
good as we can get" until we find a data source with actual VOR magnetic
offsets. We can use VOR offsets from some fixed date, but not all VOR's
were installed on the same day so no matter what date we pick we will be off on most of them.
