how do you trim the A320?

Recommended Posts

How the heck do you trim a A320? whenever i hit my trim key it doesnt trim the plane. When i look at the trim wheel i see it move like one notch and then move right back, as if it is locked or something. Anyone know what to do or why it does this? thanks.

For the 100th time, the A320 FBW system autotrims the aircraft. Just point to the required pitch and let go. The fly by wire will take care of trimming it.I would suggest some reading up on FBW systems........

gjharrall You mentioned"I would suggest some reading up on FBW systems........"I was courious if you ment in FSX learning center and or if there some other links you might reference for us. I have a basic understanding of "fly by wire" but a lot to absorbe in refence of responce times and charateristics. I appreciate any help.Thank you.Mark.System:OS:MS Windows XP Professional, Ver 2002 Service Pack 2 Hardware:Intel Pentium® 4 CPU 2.802.84 GHz, 3.00 GB of RAM Radeon X1600 Pro 512MB running a 21/19.6 Sony Flat Screen Tubed Monitorand a 17/16 NEC/Mitsubishi Tubed MonitorGeForce FX 5200 128MB running a NEC/Mitsubishi 18 Flat Panel

Yea sorry, I should have read before i posted (noticed it like 10 minutes after i posted). I see the FBW part but I did not see in any of the posts anybody who actually had it FBW correctly (or workably i mean) that is, When i am at cruise and set my pitch, the plane still either slightly climbs or slightly descends.

I hadn't even thought about the FBW trim, but I did use the Airbus for a flight across the Hawaiian Islands for the "wing" view. I noticed that it held trim very close, almost as if on auto-pilot, but not completely. I would suppose that's as good as it could get without actually setting the A/P.L.Adamson

I dont like that FBW stuff. When I'm flying the airbus, I bring up the overhead panel, and turn off all the flight computers. Then you can fly it as you like including not hearing it cry about your "sink rate" while you're landing :(

No, the real joke comes when you try to find this kind of information in the Learning Center.Just something else the ACES team `forgot`. There is no detailed technical information on the Airbus in the sim, and some of what is there is a direct port from the 737, and just wrong.The only question is whether it was done deliberately as part of the innate parochialism of the FS product or whether it was a symptom of the rush to finish.In either case, it needs fixing in the first patch, pronto.

Agreed, but it's not exactly hard to look up FBW on the net now is it?If you are a 'newbie' with FSX, I would suggest that you have more pressing issues to deal with, like 'how to get it to run on my 2 year old Dell?'Hopefully a good % have found there way to AVSIM.........Glenn

Not sure if this is a helpful remark.you see the point is that it's pretty much impossible to fly it straight and level as the input from primitive FSX controls as over sensitive near the null zone. In other words, yes, the FBW (Fly by wire) system on the real aircraft will trim the aircraft the bottom line is a CH PRODUCTS Yoke/flightstick is not up to the same feel as the real thing.Net result is it's not really possible to fly the FSX Airbus by hand and to be fair this is not often done in the real world either. Airbus is a pretty much automatic flight system though I'm no expert on it.I could find out though because I've got 5 developers building one for me for commercial release later this year, early next year.If there are any real airbus pilots who would like to help out with testing later or even in the alpha stage please let me know.p.wilding@btopenworld.com

I would think that the airbus in real life, just like the other FS planes is about 500 times easier to fly--I have flown Cessnas for real and I know there is a universe of difference :)

yes, agreed.I fly real aircraft too when I get the chance. And yes, a huge difference how real aircraft fly.On the plus side in general I would say the ground effect and feel in FSX is superior to FS9.On the down side joysticks and input controls still feel nothing like the real thing.One of the biggest reasons is because fSX does not handle aircraft properly. For example, in a real aircraft when you push the nose down then let go of the stick it will oscillate and gradually come back to around the same level and pitch it was at before.In FSX/9 push the stick down and you'll end up in an over speed and a dive bomb and though it may oscillate the frequency will will far too low and the amplitude far to big.So when people say this has been tested they should give a report that says, and breaks down each aspect that's done well and not simply say. "tested by real pilots" as if that makes it right.I'm working on various aircraft for FSX and expect to see some changes in this respect and the way certification is going to work for our aircraft.Peter

Peter,Manual flight in various situations using the sidestick is common practice in many airline SOP's for the Airbus, primarily coupled with the use of autothrust.

Interesting.It's going to be hard to fly manually the FSX version of the Airbus.I'll have to ensure the team I've got working on a commercial one get this aspect realistic for FSX.Peter

I have imported the PSS A320 and in general it works well except no AP on approach. I never use AP for approach (not even with a B737). Usually I land with Autotrust but handle the rest manually, I consider my landings good even with 15 knots cross winds (accoridng to my specs which may be wrong). What I learnt is only from FS (since FS98), reading these forms, manuals and experimentation, I have never been in a cockpit and I tought I share how I do my landings in case somebody can guide me to improve them and be more realistic.In general I make sure that the airplane is within acceptable weight, not more the 30% fuel on board. I use the FMC to read the landing speed at full flaps. When the glide slope is within the capture area (around 10 miles out and 3000 feet) I make sure that I am at around 135 to 140 as regards speed and also full flaps (usually as indicated by the FMC), next push on the joystick to set for the decscent rate, then wheels down and arm auto spoilers from then onwards using the joystick to adjusting the pitch to keep within acceptable decent rate and have the glide slope and localiser within limits. When runway within sight I continue visual approach to correct for winds, when within 50 feet I will switch off autotrottle and go to idle. Revers trust and brakes after touch down.I wish to know how I can be more realistic, I am sure there are many experts around who can point some wrong doings.Tony
