 Beautiful model Fred!  Here are some files that will get it into the air.
The
 aero model uses A320-200 metrics with 737-300 aerodynamics and flight
control
 system.  The CFM-56-5 engine is based on the CFM-56 I'm using for the 737,
 except the thrust is increased to 25000 pounds (published range is 22K to
 27K).  You'll have to edit the A320-jsbsim-set.xml file to suit your
needs.
 I've included a shell script called a320 that I use to launch FG with
the
 A320.

 I'll work on an A320 flight control system when I get a chance.

I am trying to animate the rudder but it seems that the property
/surface-positions/rudder-pos-norm stay at 0. The property browser shows
a changing value for the 747 yasim model and the c172p jsbsim model, so
my joystick ( and my mouse ) is ok.

OK, that's it. I remember seeing engine properties alternating 0 and some value.
I also remember a past thread dealing with that. 
I don't have initialized the fuel load ( I have not used your scripts,

 Actually, the better solution would be for us to fix it.  Can you remind me
 when this bug was reported (if you recall)?  I'll try to have a look at it
 in the very near future.

It looks like two bugs, which were discussed a month or two ago, although I 
don't know if they were reported via an official channel, partly because I'm 
insecure enough in my coding ability to believe the problem is probably at my 
end in every case.

This first problem is in defining a fuel load in a JSBSim model.  I see 
several ways:

In the aircraft configuration file:
AC_TANK TYPE=FUEL NUMBER=0  !-- left --
  XLOC   520.0
  YLOC   -80.0
  ZLOC   -18.0
  RADIUS   1.0
  CAPACITY 10200.0
  CONTENTS 0.0
/AC_TANK

In the aircraft -set file:
 sim
  descriptionBoeing 737/description
  flight-modeljsb/flight-model
  aero737/aero
  fuel-fraction0.5/fuel-fraction

In the aircraft -set file again:
consumables
  fuel
   tank n=0
 level-gal_us archive=y117/level-gal_us
   /tank
   tank n=1
level-gal_us archive=y117/level-gal_us
   /tank
   tank n=2
level-gal_us archive=y220/level-gal_us
   /tank
  /fuel
/consumables

And in the command line:
--prop:/consumables/fuel/tank[0]/level-gal_us=290.0
--prop:/consumables/fuel/tank[1]/level-gal_us=290.0

Somehow, using combinations of the above methods, I've managed to get 
airplanes running with a fuel load that is randomly empty.  And a couple 
times I've managed to get a fuel load approaching infinity.  Users normally 
only notice when the FGSimTurbine reacts badly to a zero-fuel condition, 
which is caused by the FGEngine::Starved flag fluctuating between true and 
false, which I believe is a separate bug.

This is probably the conflicting initial fuel load problem between 
FlightGear and JSBSim. It looks like the proper solution would be for 
JSBSim to check whether the fuel load is already set or not before using 
the JSBSim configuration file specified value.

You've obviously never seen an Aeroflot flight before. :)

When they first started flying into KSEA in the early 90's, there was a
big flap about one pilot preparing a picture perfect approach.  To I-5.
Fortunately, he either noticed or was notified in time find the OTHER big
concrete bit he needed to land on.

I once witnessed an Aeroflot jet on approach to KSEA that had an
alignment problem actually horse the jet into a 45 degree bank, haul it
about a quarter mile to the west to get on the right approach.  Freaked me
out on the ground just watching it.  I don't want to think about what
those poor passengers were going through. :)

There's an old joke that goes something like this:

Aeroflot Pilot:  My, these American runways are VERY short!
   CoPilot:  Yes, but look how incredibly WIDE they are!

Reminds me of my flight into Bologna last year in one of go's (now
Easyjet) latest 737-300s -- there was a period of about 10 minutes
when we never flew straight. But they eventually managed to get the
thing aligned, and we did fly the last couple miles in a straight
line... Mind you, it's not normal on a passenger flight to see the lit
runway in its full glory head-on from a passenger window, but that
time we did...

Actually, I've flown on Aeroflot on several occasions, including domestic
lines (Moscow-Novosibirsk), and the flight has always been OK. What I
would say is that these pilots probably have a lot of merit trying to fly
these aircraft when the company doesn't always have enough money for
decent maintenance.

 My wife and I were flying Vangaurd airlines (now defunct?) into Kansas
 city (on a 737) a couple years ago and on *very short* final the pilot
 made us all temporarily weightless to get back down on the glide slope
 quickly.  Recent x-rays show that my wife's fingernails are still
 embeded into the bone of my left forearm.  It was a windy day, but not

This reminds me of a flight in a British Airways 757 back in 1993,

Since David is making a JSBSim version of the A-310, you 
can use the JSBSim flight control capability for the 
flight control system.  If you have the flight control 
block diagram (or can craft a suitable fascimile) you can 
model the FCS.  There is some rough documentation at the 
JSBSim web site, but I am in the process of creating much 
better documentation for the flight control system at the 
moment. I'll need a couple of more days for that.

 What about fly-by-wire ? How can it be taken into account ?

I'll try to work up an alpha limiter and bank limiter using JSBSim's FCS.

Beautiful model Fred!  Here are some files that will get it into the air.  The 
aero model uses A320-200 metrics with 737-300 aerodynamics and flight control 
system.  The CFM-56-5 engine is based on the CFM-56 I'm using for the 737, 
except the thrust is increased to 25000 pounds (published range is 22K to 
27K).  You'll have to edit the A320-jsbsim-set.xml file to suit your needs.  
I've included a shell script called a320 that I use to launch FG with the 
A320.

I'll work on an A320 flight control system when I get a chance.

Thank you Dave. I now have to begin the animation stuff.
I will try all these files as soon as I can.

Hello,

just a note to say that I am in the process of modelling an 
Airbus A320 : 
http://perso.wanadoo.fr/frbouvi/flightsim/a320-fb-fgsd.png

No animation and gear yet but it is progressing.
I am using Blender and GIMP, and I have to say that so far,
is has been quite easy.

If someone wants to contribute a flight model, go ahead.

-Fred

All necessary data for a YASim A320 can be found here:

http://www.bh.com/companions/034074152X/appendices/data-b/table-1/default.htm
(The A320 uses the V2500-A1 or V2522-A4 engines)

While we're at it, Fokker and Embraer have been mentioned here before:

http://www.bh.com/companions/034074152X/appendices/data-a/table-8/table.htm

http://www.bh.com/companions/034074152X/appendices/data-b/table-4/default.htm
Fokker 28: RR183-555
Fokker 100: Tay-651
http://www.bh.com/companions/034074152X/appendices/data-b/table-5/default.htm
Embraer 145: Allison-AE3007
Or the full list of aircraft and engines:

http://www.bh.com/companions/034074152X/appendices/data-b/default.htm
I think a nice project would be a stand-alone utility which asks for 
these values and creates a YASim (or if possible a JSBSim) configuration 
file.
