The attached patch adds "Hide yoke" to the c172p menu, adjusts the gear spring forces and damping to cause a more tail low attitude sitting on the ground, optimizes vertices and surfaces in c172p.ac, as well as cleaning up the tabs and indents in several xml files.
Patch goals:
1. Implement instrument and pannel lights controled by the nav-light switch.
2. Use Instruments-3d/vor which includes GS flag and filters for smooth movement of cdi and gs needles to and from parked position.
3. Adjust model and pilot view per the agreed to changes in Re: [Flightgear-devel] c172p pitch at cruise question, 12/06/2008 02:27 PM. These changes were never committed.
This is what currently is done in flightgears model loading stage anyway.

deserves.

This is a patch to the c172p fdm to add pointmasses for all four
occupant positions and baggage. The X locations were taken from the
c172 type certificate 3A12 dated September 15, 1998. As the new
pointmasses have a weight of 0 they will not affect the current model,
however we are extending the FlightGear weight and balance dialog for
JSBSim and the pointmasses have to be defined.
- Automatic pitch trim (use autopilot/KAP140/settings/auto-pitch-trim to turn
on/off)
- Aural altitude alerter. Uses the same sound file as the stall warning.
- Replace custom flasher routines with nasal aircraft.light objects.
- Cleanup.
Changes:
1. remove typo from all the /Systems/KAP140.xml files
2. changes to put radio_stack in Instruments-3d
3. Add "pick" to vor, alt, hi, in Instruments-3d
4. changes to pa24-250 and pa28-161 to use 2 and 3.
5. add "pick" and "2d text in window" in 3d OAT in pa24-250
"This patch allows all the AC using the kap140 to use one kap140.nas
which includes Roy's move to "bool" values as well as the check for
power used by the pa24-250." (dp)
I put 3 patches and a sound file in this tar. The c172p... patch
removes an unnecessary patch I submitted to the c172p. It has no affect
on performance. The Instruments-3d... patch adds a working skid ball to
the tc and switches the vor xmls to using params so it is easier to
edit. It also constrains the glide-slope needle to -32 to 32 degrees.
The pa24-250... patch fixes an edit error (corrects a misnamed switch
"click", no change in performance) and adds a "squish" sound to the
primer pump action.
feature I added to the navcom-kx155.xml and the dme.xml in the
Instruments folder. I wanted to leave the frequencies, etc. on these
dark until there was voltage applied to
/systems/electrical/outputs/nav. This was accomplished by adding a
param and property alias pointing to the appropriate value. Since the
c172p "always" applies 28 volts, this made no change in the c172p, but
allowed me to model the avionics master and battery master realisticly
in pa24-electrical.nas. I put in comments explaining this at the change
points.
There is a useful "help > aircraft help" that walks you through the
start procedure and lists the key bindings as well as the key to "light
up" the hot spots.
Implement simple help system with global and aircraft specific dialogs:
The gui.nas changes have been discussed with Andy. All ac have a help dialog,
but some are empty. (This wouldn't have been necessary, as the system falls
back to the "Common Aircraft Keys" if an aircraft has no help defined, but an
empty dialog is less confusing and encourages to be filled with interesting
information. :-) I scanned all aircraft files for interesting performance
data and added some to the dialogs (stall speed, etc.) The Concorde and the
p51d have (over?)complete dialogs and can serve as examples. The format is
documented in $FG_ROOT/Nasa/gui.nas.
There is also a couple of other, minor fixes.
The following files have ugly MSDOS line endings:
$FG_ROOT/Aircraft/Hunter/hunter{-2tanks,}-set.xml
$FG_ROOT/Aircraft/A380/A380-set.xml
The Concorde-jsbsim.nas file is a useless copy of the real */nas file, which is
in Nasal/. I'was debugging the Concorde and wondered why changes to this file
had no effect ...
(Fixed Concorde in the help-ac.diff patch: don't use "interpol" keyword as
variable.)

Not yet done: independant landing and taxi lights on port wing
I've finished the emigration of the radiostack, and I've also removed it
completely. It turned out that the comm radio is completely implemented in
the ATC subsystem. I've changed the affected ATC files to point
to /instrumentation/com, but I guess that the maintainer of the ATC code
should decide wether to make it configureable, and how.
I also had to change some files in Network and Main. The changes in network
should be obvious, but the changes in Main were a bit suspect. The files
included radiostack.hxx, but they weren't directly depending on
radiostack-hxx. They were depending on other files that were included by
radiostack.hxx. I got it to compile, but I'm not sure if I included the
correct directly depending file.
For the data directory I changed every occurrence of /radios/
with /instrumentation/ with this simple one-liner that I found on the net:
find -name '*.xml' -type f | xargs perl -pi -e
's/\/radios\//\/instrumentation\//g'
Instead of me sending all the files that got changed by this I suggest that
you execute the one-liner yourself. Of course I can not guarantee that this
will work perfectly, but I considered hand editing to be not an option (I'm
lazy). I don't want to test every aircraft to see if everything still works,
I think it's better to wait and see if anyone complaints about broken nav
radios/instruments.
Here are some updates to the KAP140 autopilot in the default c172. It now uses
ailerons and elevator instead of aileron-trim and elevator-trim. I've started
to "upgrade" it to the "two axis altitude preselect" version. Vertical speed
select rounds to nearest 100 fpm.
I've also modified the c172 electrical configuration to turn on the gps
instrument.
Perhaps the most important change is that the nasal script for the KAP140 has
moved from data/Nasal to the c172p aircraft subdir. So it is important that
you delete data/Nasal/kap140.nas. Having the kap140.nas script as a global
script was not a good solution. Now it is aircraft specific, and thus
included in the c172p-set.xml file. Ideally I would like it to be instrument
specific, so that it would be included whenever the KAP140*.xml instruments
where included on the panel.
Here is the KAP140 Two Axis Autopilot update.
I think it's fairly complete now, all the modes are working. I tested the
localizer and glideslope hold and it was pretty stable all the way down to
the middle marker.
In the pilot guide for backcourse hold (REV) mode it says to reset the heading
bug to the _front course_. I haven't figured out how to implement this so for
the time beeing one should reset the heading bug to the _backcourse_. Apart
from this the panel should operate identical to the way the pilot guide
describes.
Here is the KAP140 Two Axis Autopilot.
Aircraft/Instruments/KAP140TwoAxis.xml
Is of course the instrument config file.
Aircraft/Instruments/Textures/KAP140.rgb
The texture.
Nasal/kap140.nas
Most of the work is done here. Without Nasal I don't see how I could implement
the NAV-ARM modes and the flashing annunciators.
Aircraft/c172p/Systems/KAP140.xml
The autopilot PID controllers configuration file. Maybe this file should be in
a more accessible directory and not hidden deep inside c172p!?
I've also attached the changes to the default C172 to include this autopilot
in the 3d-cockpit panel and the 2d vfr panel. Or at least I hope that I've
managed to include all that is needed.
I added some more hotspots to Davids c172p since he already had done all the animation. Also I tried making the throttle and mixture knobs into hotspots even when they are moving adding extra hotspots for them. Also you can click on the trim wheel to trim now.
I added a directory for the labels for the white toggle switches, but there is probably better way to do the labels then I came up with. There is a short readme file which gives the path for the new directory.
Make the plane much sloppier at high alpha and/or with the flaps
extended. In slow flight, there's much more lateral instability now,
and adverse yaw is more obvious at the start of a turn using only
ailerons.
activated with the mouse, but they do respond to the following
properties:
/controls/lights/taxi
/controls/lights/landing
/controls/pitot-heat
/controls/lights/navigation
/controls/lights/beacon
/controls/lights/strobes
- yokes
- carb heat
- throttle
- mixture
- flap switch
- trim wheel
Moved the pilot seat back slightly.
Use LOD more aggressively, so that all the interior detail is skipped
when the viewer is distant.
