A380 Support - Models & FDE Issues

D-AIPB · Post by **D-AIPB** » 29 Jun 2010, 19:44

Is it possible that the designers have forgotten to put Autotrimm into the A380 ??

Thanks
Kind Regards

"Forgotten" is not the right word, I don't think they modeled the airbus fly-by-wire aspects. Thats very hard to get ride for simulator.

Wing bleed through...

Also if you stop with the nose gear turned shouldnt it return to center?

Ben F. · Post by **Ben F.** » 30 Jun 2010, 02:15

Also having autopilot issues, seems to be very unstable. Constantly chasing VS, course, speed, etc.

Post by **Derek Mayer** » 30 Jun 2010, 02:35

Unfortunately, none of those issues are likely to be fixed soon. The wing bleed is pretty minor, and only visible from specific angles. Might get looked at if we ever put out an update, but I don't anticipate updating just for that.

I never had the autopilot issue, and either way we don't have an FDE designer with us. Though if any FDE designer out there wants to try fixing it they're welcome to.

The nosewheel steering isn't a bug. When you stop your car in mid turn, do the wheels magically return to center?

Thanks for the report!

what panel are you using for the aircraft? default 747 panel has been tested & works fine with us AFAIK

Post by **Derek Mayer** » 30 Jun 2010, 03:26

Quite right. Auto-trim (and other Fly-by-wire features) need to be coded in the panel's gauges. We haven't included a panel in our release, and therefore haven't modeled any fly-by-wire simulation.

Np, just thought I'd bring it up incase you didnt know.

Nose wheel steering thing must be from watching/flying the CRJ too long lol. When the tiller goes back to zero and stopped in a turn I believe it goes back to center.

Report all Model & FDE issues here

I have flown EDHI-LFPG with the default 744 panel and I have noticed the autopilot having a tendency to chase the directed flightpath. Though I have previously tried flying LFPG-KIAD with it and the autopilot did not give me any headaches, so it's hard for me to pinpoint anything that may cause it.

Also I have noticed it tends to shake an awful lot. Anything that can help with that will be greatly appreciated

Tranceaddict · Post by **Tranceaddict** » 30 Jun 2010, 05:22

you'll do know winds can play a factor? esp if you'll have real world weather updates loaded via Activesky etc

Also if using a joystick, you'll might wanna look at the calibration/FSUIPC updates - same goes for FSUIPC's weather functions

Post by **Derek Mayer** » 30 Jun 2010, 07:09

As it turns out, the wing bleed through is worse than I thought. I'm still undecided on whether it will be updated in the future.

its the lazyness on some modellers part that it does that.

I too have had trouble with the autopilot with the default 747 panel installed. It tends to loose the virtical speed hold for some reason. Had this happen twice already on two different flights.

Another problem ive had is the engine rolling back while on autothrottle as its approaching final cruise speed in level flight. Its like instead of bringing the engines back gradually, it brings them back to 0 for about 2-3 seconds and then takes it back up to the power setting it was previously at before the rollback, then starts to gradually roll it back. This has happened on all of my flights so far.

Tranceaddict · Post by **Tranceaddict** » 30 Jun 2010, 08:03

if you're climb rate specified on the VS is too high, it will do that. The trouble we had with the default 747 panel was the over-aggressive capture of the altitude. That was however sorted out with the FDE updates. The A/p was an issue before but doesnt seem to give us that problem. or atleast me.

I'll prolly check it on a short flight later.

zherin · Post by **zherin** » 30 Jun 2010, 09:03

Just wanted to throw my comments in the bag. Absolutely stunning model. No complaints. No bleedthrough for me. The autopilot is TOTALLY jacked though. Thus far, no problems maintaining altitude...but airspeed is a whole 'nother story. It's interesting...the A319 does the EXACT same thing, but not the 318 or 320. Now the 380. Guess I'll just monitor the throttle for 17 some odd hours from LAX-SIN! Awesome model work though. WELL worth the wait!

Ive had a problem where i keep stalling/loosing speed in accent therefore it takes me ages to get alltitude. I am using the Overland panel but am going to try the default one provided.

zherin · Post by **zherin** » 30 Jun 2010, 09:15

It's probably because everytime you hit A/S hold on the autopilot panel, the throttles pull all the way back, you lose airspeed, lift, and thus stall

Fun times. Just screwed with the airspeed all the way to SFO. 16.5 hours to go.

Movieman162 · Post by **Movieman162** » 30 Jun 2010, 09:33

The aircraft now rocks forwards and backwards after 30,000ft meaning i cannot get above that on autopilot. Please help.

Never had that problem during testing. Are you using the default panel? What's your cruise speed?

Yeah is the default panel speed is between 280 and 350 and climb rate is 1500

Could It be fsupic

cka411 · Post by **cka411** » 30 Jun 2010, 12:28

I'm experiencing the same autopilot issues with the default panel. Attempted to do WSSS-EGLL, with the key word being attempted, would assume that full fuel would be appropriate for a trip that long, but I may be wrong with that. Even on a short hop from EGLL-LFPG, I noticed the autopilot had a tendency to really to shoot through altitudes and be unstable as far as establishing and leveling off on a heading, it looked like a gradually reducing sin curve. The auto throttle I found kept reducing to a lower setting that would not really sustain flight, the power setting on N1 looked appropriate but as far as maintaining flight, not so much. The visual model, stunning, and the wing bleed through I noticed a lot on the climbout when pitching up, was very noticeable.

I realize any modifications are not supported, it's more of an observation than anything else. The auto throttle max RPM rate in the aircraft.cfg is 90, sounds good, change it to 105, I know I know, excessively high, avoid throttle reduction. As far as the rest of the autopilot goes, I have no idea what would need to be done to fix that.

Im in the same boat as you mate just couldnt describe the problems better myself. Im going to see if the removal of the FSUPIC.dll file has any problems as that may be the cause for fsx users at least.

Hello again!
Congrats on the A380!! I just love it

1st test flight was from Dubai to Heathrow!!

But.. I also had the same issue with the autopilot above 30.000ft and the issue with the a/s hold. I changed the numbers on the aircraft.cfg the autopilots max rpm and the a/s works ok now. But I am still having the problem with the altitude VS. Above FL300 the plane tries to level up but something's going on with the stabilaser on the tail. So the plane is just doing some roller coster ride : P.I had to deactivate the alt hold change the stabilaser to 2.0 degrees and turn it on again to work. I haven't tested with the 747 panel though.. I used a a340 panel I had and also the spolers arm button didn't work (probably this is panel problem) . Oh and I had FSPassengers loaded too.. and Active sky weather... I shall do some tweeks this afternoon to determine the problem though. Probably will try with another panel.
BTW the wing flex is supperb!

I had some turbulance over hungary and I loved how the wings moved!!

Cheers
Dot!

Movieman162 · Post by **Movieman162** » 30 Jun 2010, 13:03

Ive i may just ask you guys, dotsalgon and cka411 do you have FSUPIC on?

dotsalgon · Post by **dotsalgon** » 30 Jun 2010, 13:07

um yeah!
Active sky doesn't connect to fs without fsupic... I don't have the registed version though..

Post by **DerKranich** » 30 Jun 2010, 13:11

I've had the same issues and I do NOT have FSUPIC.

I've been running the A380 on FS9 and am currently using the default 747 panel. Blasphemous I know, but I want to get these things with the FDE ironed out before doing much with it.

EDIT: I might have found a way to compensate any oscillations.

hmm, i don't have the problem but, at the moment i'm flying from Heathrow(EKLL) to Dubai (OMDB), she flyes great and taxies on the taxiwas very easy and nice ^^

What is your altitude? Try and change the altitude by 3.000 or 2.000 ft and you'll see LOL

I'm at FL290 but was at FL350 to test it, so now I#m descending...

Post by **GaryG** » 30 Jun 2010, 13:38

I know it's nobody's fault, I know that it is not supported... All I want to say is, if only there will be an FSX compiled model......

No request, just a thought, you know me

Movieman162 · Post by **Movieman162** » 30 Jun 2010, 13:46

Right i removed FSUPIC and that stopped the roller coaster motion. But at FL350 the aircraft pitches up mad yet somehow still flies. I think theres a problem with the weight and fuel of the aircraft and that in turn is affecting the FDE. Also the Autothottle cannot hold a speed.

Post by **esg** » 30 Jun 2010, 13:55

We can't fix a problem we can't recreate

Air Berlin · Post by **Air Berlin** » 30 Jun 2010, 13:56

well, just take the panel i have and everything will work !
autothrotle autopilot etc. just loook...
i have tested all functiones and brought this baby to the limit...FL370 at everyting was quite fine...
i don't know what for panels are you using ?? just tell me and i can help.

Seriously, I can barely adjust the throttle without it doing that. Either my joystick isn't calibrated, or the thrust scalar is way off.

I noticed that when I had the same problem.. I was also flying with a simulator speed X4 and cruising x16 and I had to reduse the simulator speed to normal to fix the roller coster ride. Could that be the problem?

Tranceaddict · Post by **Tranceaddict** » 30 Jun 2010, 14:31

those shots say it all. I'm not surprised you're experiencing a stall.

you expect to climb straight out on takeoff @ 1500 fpm? then you expect to continue 1500 fpm climb to TOC @ 35000 feet or Initial cruise alt of 35000 feet carrying.. erm.. 555200 lbs of fuel??

dotsalgon · Post by **dotsalgon** » 30 Jun 2010, 14:32

Movieman162 your plane though is fully loaded with fuel.. :S

Movieman162 · Post by **Movieman162** » 30 Jun 2010, 14:35

Well what should i do?

dotsalgon · Post by **dotsalgon** » 30 Jun 2010, 14:37

Reduse the fuel.. either by the setting of the FS (is I remember correct is in Aircraft menu -> Fuel and weight "or something").. or by running FSPassengers.

Tranceaddict · Post by **Tranceaddict** » 30 Jun 2010, 14:40

You know before raising these issues and confusing people, you should seriously learn the basics of flying & while you're at it, flight planning including weight & fuel planning.

Have you heard the concept of step climbs??

xparamorex316 · Post by **xparamorex316** » 30 Jun 2010, 14:44

Has anyone tried the A380 with FSPassengers yet. For some reason the plane keeps ending up overweight before i even load people on.? And i don't want to edit the Aircraft.cfg to see if it can be fixed without consulting the Pairbus team first.

I tried it... but I didn't full her up!! You have to calculate how much fuel will need for the trip...
