This patch contains bugfixes from my previous patch
(i made mistakes when using "diff" utility last time):
1. Now ATC do not tells us to go around because of
traffic on RWy, when that traffic is WE.
2. Now ATC don't say that we must follow ourself
(like "GFS, number two, follow GFS on final").
And new Tower-ATC features:
1. Requesting departure clearance. When you are
on taxiway, you can request departure clearance.
Tower will answer with something like:
"Line up runway two eight right".
TODO: check if any AI-Planes on final and tell
something like: "After the landing AI-CALLSIGN
line up runway two eight right".
2. Requesting take-off clearance. If you are on
runway, you can tell to ATC that you are ready
for take-off. So, Tower will tell you that you
are cleared for take-off (or immediate take-off).
3. Reporting landing gear position on final by pilot.
If you are on aircraft, which landing gear can
be UP, when reporting final you will tell
"Gear down, ready to land".
4. Reporting landing gear position on final by ATC.
When i was newbie and was flying on Cessna 310, i
ALWAYS forgot landing gears on final. Now if you are on
final and forgot landing gear, Tower will tell you:
"LANDING GEAR APPEARS UP" or "Check wheels down and
locked". So you will have some time to push gear
down or execute missed approach ;)
5. ATIS phonetic ID in requesting landing message.
In FG pilots says: "for full stop with ATIS" everytime
(when airport doesn't have ATIS too). But in real life
pilot saying phonetic ID of ATIS message. Now we have:
"for full stop, information alpha ... / ... zulu".
If airport doesn't have ATIS, pilot don't say this.
TODO: add this feature to AI-Planes too.
6. Advising weather condition in airport by Tower.
If you are requesting take-off or landing in airport
that doesn't have ATIS service, Tower will tell you
about wind direction and speed, visibility and QFE.
7. Reporting downwind if missed approach. When some AI-Plane
is on final FG's ATC tell you to "continue approach".
And then you lost radio transmission. Now ATC says:
"continue approach and report left/right downwind".
And now we have "Report Downwind" entry (button)
in "ATC Communication" form.
This also fixes distortion weirdness in the osgviewer version. That
was caused by osg::GraphicsContext getting in the act on resize events
and adding its own scaling to the projectionOffset of slave cameras!
The LOD far range on the tile entry scenegraph node was initialized to
0. This meant that any traverals of active children that happened
before the tile manager updated the node would ignore the node
altogether. Among these is the groundcache traversal which was failing
at startup even though scenery was loaded.
Also added a function to dump scene graph nodes to files; very handy
in gdb.
Make an OSG file reader for .stg files.
New class flightgear::SceneryPager, which is a subclass
osg::DatabasePager to handle explicit delete requests.
Modify FGNewCache, FGTileEntry, and FGTileManager to use
SceneryPager. Mostly this involved removing the queues that talked to
FGTileLoader.
Calculate accurate tile timestamps from the time they are traversed in
the cull stage (which means that they are visible) instead of updating
them periodically.
Replace tile entry transform and range node with one LOD node
This fixes a race condition when teleporting somewhere outside of the
currently loaded scenery. Before, if there was no valid scenery, an
aircraft might end up at the center of the earth...
Instead of just reporting that the magic number, length, etc. of a
multiplayer packet is invalid, abort processing this packet. Also,
check if enough space remains to send a property string.
