May I suggest renaming this ...something like ''Airbus A340 Family'' ? :D

We do need the last and my favorite A340,the -500 to have a complete family,but I think this will work too.

I work with Martien van see P for exterior models. When we're done with the KC-137 model, I'll see if he'll shrink the A340-600 down to a 500.

Hello,

One issue concening all of your A340s, when I download them, the models dont show up, I can start the sim, choose them, and start a flight, but the aircraft just dont appear. Can anyone tell me something about this, how to solve it?
Thanks

Make sure you remove the -master from the end of the folder name. If it still doesn't work, let me know.

Now the planes of -600 have EPR on the engine display:

Is it somehow possible to change the key which arms the ground spoilers on the A343? Right now it's ''equals'' key. Is it possible to change it to Ctrl-K for example? That one is used on A330,and A320 Fam.

Sure.

You can also arm them by clicking the spoiler lever.

There is one more interesting thing. I click on VOR LOC ,but nothing happens. But,when I click on ILS ,the plane lines up and starts to auto-land....anyway,it's important that it works finally.



Other thing,your ITAF repo,help file,

Note: Autoland and AT retard require correct /position/gear-agl-ft. This is done automatically in Yasim, not in JSB. You will need to do that yourself.


What and how to do yourself?

@berkut
OK, I check the VOR/LOC logic.

[off topic]
There is a block of code in nasal which does it, I'll add that to the Help.txt but here it is basically:

Code: Select all
var aglgears = func {
    var agl = getprop("/position/altitude-agl-ft") or 0;
    var aglft = agl - 8.004;  # is the position from the Aircraft above ground. Change this until the /position/gear-agl-ft = 0 when flat on ground.
    var aglm = aglft * 0.3048;
    setprop("/position/gear-agl-ft", aglft);
    setprop("/position/gear-agl-m", aglm);

    settimer(aglgears, 0.01);
}

aglgears();

Add it to any nasal file.

I started my Fly By Wire System. The first realistic Airbus FBW for FlightGear. (as far as I know). Work in Progress.

Aircraft is flown by the pid-controllers, but the joystick commands them. For testing, I have basically simulated 4 laws and 3 modes:
NORMAL law: roll and pitch sent to pid-controllers, then to surfaces. 30 degrees maximum bank, unlesss sidestick input is past halfway, then it's 65 degrees. Pitch minimum is -15 degrees, maximum 30 degrees. Autotrim functional.
ALTERNATE law: roll and pitch sent to pid-controllers, then to surfaces. No bank or pitch protection. Autotrim functional.
DIRECT law: roll and pitch go right so surfaces right away! No bank or pitch protection. Autotrim disabled.
BACKUP law: roll and pitch from sidestick disabled, use rudder for lateral, pitch trim for vertical. No bank or pitch protection. Autotrim disabled. Ailerons and Elevators neutral.

Modes:
FBW mode: follows FBW laws from above
AP mode: uses DIRECT law, damping/limits done by IT-AUTOFLIGHT System. Joystick disabled.
FLARE mode: Active 50ft from ground: Pitch in DIRECT law, Roll in NORMAL law, Autotrim disabled.

I will further simulate it at a later point in time, when FBW flies stable. You can switch modes via the A340-600VIP menu.

Only the A340-600VIP workshop has it right now, because it is unstable! It needs testing, and ALOT of testing, and more fixes. If you could try, I would appreciate!
NOTE that it is UNSTABLE! It works -- well enough to fly.

Much better PFD, model from A330_artix_dev, code all rewritten:
Image

I have a flashing LVR CLB implemented, full map to ITAF

Thrust System has been updated, if the A/THR light is on, pulling the throttles back out of CL, shows THR LVR, and reduces the amount of thrust A/THR is allowed to use -- like a real Airbus. when set IDLE, A/THR goes fully off.
MAN MCT and MAN TOGA implemented. MAN FLEX will come later.
You can also reduce individual engine's thrust allowance A/THR.

With A/THR off, thrust is set manually from 0 (idle) to the cl limit at cl detent, but A/THR doesn't go on until it's armed (MAN MCT or TOGA) or the A/T button is pushed on either the IT-AUTOFLIGHT GUI or the MCP panel.

Also the A/THR light turns BLUE when A/THR is armed!

Best,
Josh

Fuel burn waaaay to big on the a343. After just 350-400 nm,50t of fuel was gone.

What the hell?

Will check this, thanks

EDIT: Fuel burn to high on all A340s. Thanks for the bug report.

Found the fuel burn.

It won't be fixed quite yet, I have in my A346VIP some in progress changes, including FBW, and a new MCP model, once I get that all sorted, I'll fix the fuel burn.

OK I know it's been absolutely ages, but here is an update:
* Improved: MCP in Flightdeck from A320Family
* Upgraded: A3XX FADEC System from A320Family
* Fixed: Spoiler arm lever not working until 2 clicks
* Fixed: Callouts, Retard, 10 5ft
* Fixed: Various other little things
* Upgraded: Newest IT-AUTOFLIGHT installed, now eligible for automatic updates.
* Improved: New Autopilot tuning Configuration
* Removed: IT-FBW (A340-600VIP ONLY, see below)
* Upgraded: New PFD from A320Family

I just pushed them to the A340-600VIP, and will be backporting my changes to the other A340s within the next hour or so.

Again available on FGMEMBERS or on it0uchpods repo: http://www.github.com/it0uchpods/

FBW:
Not possible with Yasim, this is due to many things which I don't want to type out right now (if you want to know, say so)
So I removed it from the -600VIP and will not be developing that version again.
I may try to make a system which mimicks FBW, but it will never be a real FBW system unless I convert the A340s all to JSBsim, which wouldn't happen for ages, since I have enough projects at the moment.

Kind Regards,
Josh
