Allow multiple, space-separated waypoint specifications to be added to a
route, rather than having to type each one and press the add button
each time.
If no waypoint is selected as the insertion point, show a message
and leave the waypoint input intact, rather than just clearing it.
Update the help label to reflect the change and include a note of how to
create offset waypoints using a radial and distance.
At the suggestion of Gilberto AGOSTINHO, add
button bindings for throttle, mixture and prop
to the joystick configuration dialog.
Specific use-case is users of game-pads, but also
useful to users with a single throttle axis on their
joystick.
This follows from http://thread.gmane.org/gmane.games.flightgear.devel/78650 and
resolves the sign bug https://sourceforge.net/p/flightgear/codetickets/1778/ .
Combined with a matching change to the flightgear repository, this changes the
HUD formats from the current set of 3 (note that the text in brackets is not
shown in the HUD preferences PUI dialog, but is show here for reference):
0) Decimal degrees (37.618890N -122.375000W)
1) Degrees, minutes (37*37.133N -122*22.500W)
2) Degrees, minutes, seconds (37*37 08.0 N -122*22 30.0 W)
to (here the text in brackets is shown in the PUI dialog):
0) DDD format (37.618890N 122.375000W)
1) DMM format (37*37.133'N 122*22.500'W)
2) DMS format (37*37'08.0"N 122*22'30.0"W)
3) Signed DDD format (37.618890 -122.375000)
4) Signed DMM format (37*37.133' -122*22.500')
5) Signed DMS format (37*37'08.0" -122*22'30.0")
6) Zero padded DDD (51.477500N 000.461389W)
7) Zero padded DMM (51*28.650'N 000*27.683'W)
8) Zero padded DMS (51*28'39.0"N 000*27'41.0"W)
9) Trinity House Navigation (51* 28'.650N 000* 27'.683W)
Add valid ranges for day based on selected month and year taking into account leap years.
With this change it should no longer be possible to enter an invalid date.
Added combobox for the month (using name).
Added sliders for all date components (year is between 1971 and 2037 to avoid invalid values in time_t).
Relabelled easing, added a bit of layout context with some ruling.
Magnetic declination being "the direction of the horizontal component of
the magnetic field measured clockwise from north" according to
MagneticField(1), it must be substracted, not added, from true bearings
in order to obtain the corresponding magnetic bearings.
Example illustrating the bug:
Start at KSFO, open Equipment -> GPS Settings, enter KHTH as the
destination and click on "Search". Before the bug fix, the dialog
gives a bearing of 85, whereas the correct magnetic bearing is 58.
Digging a bit further, the true bearings/azimuths for the shortest
path (geodesic line) from KSFO to KHTH are approx. 71.5 at KSFO and
73.8 at KHTH. This can be verified with two independent libraries
(GeographicLib and PROJ.4):
% echo "37d37'08N 122d22'30W 38d32'45N 118d38'00W" | \
GeodSolve -i
71.44943076 73.75785283 343987.398
% echo "37d37'08N 122d22'30W 38d32'45N 118d38'00W" | \
geod +ellps=WGS84 -I -f '%0.3f'
71.449 -106.242 343987.398
(-106.242 + 180 = 73.758: -106.242 is the "back azimuth" at KHTH for
this path)
The bearing of 85 given by the code in gui/dialogs/gps.xml before
this commit is indeed 71.5 + magnetic declination at the starting
point (KSFO), whereas it should be 71.5 - magnetic declination.
Another, more experimental way:
Start FlightGear with:
fgfs --aircraft=ufo --disable-real-weather-fetch \
'--metar=KSFO 070956Z 36000KT 10SM FEW023 11/07 A2977 RMK AO2 SLP080 T01060067' \
--lat=37.61867421 --lon=-122.37500761 --heading=71.45931
(just in case wind influences the ufo, I have no idea whether this is
the case or not...)
During your flight, progressively increase your heading (as seen in
the HUD, i.e., true heading) so that it smoothly changes from 71.5 at
KSFO to 73.8 at KHTH. You should arrive pretty close to KHTH, whereas
the initial heading of 85 given by the GPS Settings dialog is way too
high, be it interpreted as a magnetic heading (which was visibly the
intention---it would be nice to write that in the dialog BTW) or as a
true heading (in which case the result is even further from the
correct value).
expose the ai-range-mode flag to the static-lod dialog.
PagedLOD culling based on distance seems to be more reliable than that based
on projected screen size.
This is merge request #20
MP Patch first step fgdata part: nasal to check wich planes we are
displaying in the futur, with a distance check , one plane each frame.
The change introduced in commit 8c7fc119 to go to the last checklist
on open causes a problem when the first checklist has multiple pages.
If the last opened checklist did not have multiple pages, the previous
and next page buttons are still shown.
This commit runs the same binding as used by the combo box to reset
the visibility of these buttons immediately before the page is
displayed.

Now that request-metar/clear-metar commands work properly, use those
instead of direct manipulation of metar properties. Also, don't write
to properties intended for read-only use.
Replaces existing Nasal/failures.nas script with a programmable failure
manager. The failure manager allows dynammic creation and removal of
failure modes, on demand activation and a flexible set of triggers.
The public interface can be found in Nasal/FailureMgr/public.nas
Aircraft/Generic/Systems/failures.nas provides a library of triggers and
failure actuators ready to use for programming the failure manager.
A compatibility layer is included under
Aircraft/Generic/Systems/compat_failure_modes.nas.
This compatibility layer is currently loaded on startup and programs the
FailureMgr to emulate the former behavior (same set of failure modes and
compatible interface through the property tree).
This first milestone is only intended to replace the failure management
engine underneeth with minimum visible changes, and hopefully no aircraft
breakages. Future milestones will build upon this to add a Canvas based
procedural GUI and example integration on aircrafts.
