- Fixed triggering of debug assertion "altitude_callout_voice != NULL" when
altitude callouts were delayed by higher priority warnings.
- Fixed performance bug: MK_VIII::IOHandler::TerrainClearanceFilter::update
sucked CPU time (top #12 in profiler), due to complex "moving average"
calculation on a queue of hundreds/thousands of altitude samples.
Also, pausing the sim caused this queue to grow excessively (by one sample
per update loop) => resuming the sim after pausing it for a long time
resulted in the TerrainClearanceFilter sucking even more CPU time...
=> Number of altitude samples is now limited to 5 samples/sim-time-second
(still more than enough to calculate a stable average).
* Fixed segfault when GPWS finds a matching airport but no suitable runway.
* Fixed several sim deadlocks when GPWS alerts trigger at "strange"
heights (e.g. initial alert height is -5ft or 1e-29...).
* Avoid repitition of GPWS alerts below 30ft, i.e. avoid excessive
repitition when plane becomes airborne at bumpy landings.
Only block callouts which were actually issued to the pilot. When
multiple callouts trigger at the same time, allow lower prio warnings
to be issued once the higher prio ones are resolved.
=> Gear/flap warnings are now working reliably (no longer blocked
permanently when altitude callouts are enabled).
* Fix issue #139, uninitialized variable causing sim deadlock in MK_VIII::Mode5Handler::get_soft_bias
* Fix more uninitialized variables sometimes causing warnings not to work.
* Fix some warnings only working on a single approach (missing reset).
* EGPWS self-test can now be triggered more than once (missing reset).
* Implement configuration options for attitude and altitude input selection.
The quotes form is normally only used for headers with path relative
to the including file's path, though the standard doesn't strictly
mandate this. This is consistent with the rest of sg/fg, it makes the
code's intent clearer and helps to find headers. (And it's a few
milliseconds faster, too.)
static FGAirport helpers. As a result, another global index goes away. Use
the helpers to avoid ugly FGPositioned down-casts in various places.
Also converts the environment/METAR code to deal with FGAirport pointers,
instead of string identifiers, and contains work-in-progress code to implement
the AirportList dialog using FGPositioned. This isn't enabled yet for various
reasons, but is the final piece to allow FGAirportList to be removed.
gone. This is good news, since the old query was implemented as a linear
search, sorted by Manhattan distance, and with a warning not to use the logic
at runtime. Various systems (such as the Mk-VIII) do query such data often,
eg every second.
Also gets Point3D out of Airports/simple.hxx, as a precursor to removing it
completely.
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 FGRunway to be heap-based, and inherit FGPositioned. This is a large, ugly change, since FGRunway was essentially a plain struct, with no accessors or abstraction. This change adds various helpers and accessors to FGRunway, but doesn't change many places to use them - that will be a follow up series of patches. It's still a large patch, but outside of FGAirport and FGRunway, mostly mechanical search-and-replace.
An interesting part of this change is that reciprocal runways now exist as independent objects, rather than being created on the fly by the search methods. This simplifies some pieces of code that search for and iterate runways. For users who only want one 'end' of a runway, the new 'isReciprocal' predicate allows them to ignore the 'other' end. Current the only user of this is the 'ground-radar' ATC feature. If we had data on which runways are truly 'single-ended', it would now be trivial to use this in the airport loader to *not* create the reciprocal.
- Runways are now part of an airport, instead of a separate list
- Runways are no longer represented as a boring struct, but as a class
of their own.
-Improved runway access to unify various runway access methods.
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
Thanks to Vivian Meazza for debugging this. The output deque for
FGDigitalFilter was not being kept long enough for the
doubleExponential filter. Reads from output[1] could cause a crash.
SGPropertyNode to guarded ones. This is also done for JSBSim/JSBSim.hxx,
for which JSB had given explicit permission a while ago. I postponed that
back then, but now is the time.
I have implemented a Honeywell MK VIII EGPWS emulation for FlightGear.
The MK VIII is an Enhanced Ground Proximity Warning System aimed at
regional turboprop and small turbofan aircrafts such as the Citation,
Citation Bravo, B1900D, Beechcraft 99 and L410.
