MD11 banks left - right constantly..

Recommended Posts

I'm a rookie MD11 pilot (just downloaded) and assume I have set something up incorrectly. The plane banks left, then right, then left along the flight plan. It is waaay more than normal for any aircraft I have flown. I was using ASA and tried it with FSX default weather. Same thing but not as pronounced. I used the load manager to setup the planes weights and balance. I then followed the tutorial for my first few flights. Two flights a row and I need a Dramamine. :) Any guidance would be appreciated. Thanks.Bob..

You need a registered copy of FSUIPC and you need to enable the wind smoothing options included with it, also tick the turbulence and variance check boxes and your MD-11 s-turns will pretty much disappear completely.

Bit weird you need a 25 dollar program in order to be able to fly the MD-11 without problems...

You need FSUIPC to fix a broken FSX. FSUIPC is THE most important and most useful add-on/utility you will EVER buy for FSX period. $25 is an absolute steal in my opinion.

Only if you insist on flying with the "real" weather - which is broken in FSX.

Thanks everyone. I will set the wind smoothing thingy in FSUIPC and see that if helps. I haven't been able to land the plane yet as I keep getting a hard crash to the BSOD. Usually occurs a few minutes after takeoff. The video starts to break up with horizontal lines then a complete freeze. I have seen this before occasionally, but never this consistent.

I have a similiar problem in FS9 though with either ASky weather or FS weather but it only occurs when I'm over areas that are void of nav aids (ie North Atlantic etc.) I have FSUIPC with wind smoothing etc installed but the wind is not changing as it banks it steady in one direction.It will fly wings level for about 2 or 3 minutes then do about a 5-9 degree bank either left or right like its trying to recapture the flight path then bank 5-9 the other way then level out for another 2 or 3 minutes.The important thing to remember here is that this is only in areas with no nav aids. I flew EGLL to KSFO the other day in real time and was at the computer the entire 12 hour flight monitoring and it will make you dizzy sometimes. This occurs with the PMDG 737,747,MD11. I'm going to test the FS default 747 on the same flight path to see if its the same.Sean Green

Are you sure this is a FSX problem. Without the autopilot engaged, only cws mode, the problem disappears, and thats still the autopilot handling banks, right?

You will only see it when the Autopilot is trying to follow a course line in a GPS,Nav aid or FMS, wing levelling is not affected.

I see, I own the ASA program, and your hifi banner is not hard to miss, could i fix the issue with this program?

I'm seeing it with FSUIPC smoothing selected and default real time weather. The plane banks as much as 15% in response to wind speed changes. There must be a solution as this un-commanded course searching is ludicrous. Plus all of the banking is moot as I'm getting a consistent BSOD some time during the flight. I'm starting to get an $80 knot in my stomach that I'm the only MD11 captain who can't complete a flight. Arrrrg...Bob..

The FSUIPC settings need to be "aggressive." I use 1 deg/kt per 8 sec and one half the default values for press/temp variations and get rid of turbulence everywhere. Although it is not the majic bullet (that would be a complete redo on that horrible MSFS wx engine) it really helps in most cases. Don't blame this on PMDG, it is definitely a microslop problem.

But how come that i have no problem flying the plane manually, but the autopilot keeps the plane banking left and right all the time?

Create one with clear weather and no winds aloft to see if it continues to bank left and right. In my testing it still does bank left and right with no weather or winds.Sean

Hi!Sorry to bring up quite an old topic but I have just got the PMDG 747-400 for FSX and am currently flying from LHR to JFK and am experiencing the same issue as you are describing. I don't have a registered version of FSUIPC, but am flying with the weather set to 'Clear Skies' and wind velocity is 0. The aircraft is gently banking a few degrees right then a few degrees left every couple of minutes. Like you, I've only noticed it whilst flying over the Atlantic (ie with no close navaids). It's like it's continually trying to track the route.It's certainly not as bad as the problems I was having with 757 Captain (where the AP frantically shook the aircraft left and right violently), but if you were a passenger on this aircraft you'd be reaching for the barf bag after a while!Thanks,Tom Wright

You don't need FSUIPC to run the MD11. I'm running with ASA with no problems as are many others. There is something else wrong in the sim I agree, but to suggest that he needs FSUIPC to me, is not the solution, just a band-aid to some other problem.

A question for those of you with the banking left and right issues. Are you importing your flightplan into the FMC or are you actually typing all the waypoints individually into the FMC?I used to import flightplans from FSBuild into the FMC directly and had the banking issue but when I type each individual point into the FMC I do not have the banking issue. Another way to test is when it starts banking go direct to the next waypoint and you'll see the banking stops occuring until the next waypoint and then it restarts again. I think it has something to do with using a comany route or importing the flight plan.I've just started typing all my flightplans in by hand now. Seems much better now it has nothing to do with the weather system or else it would occur everywhere, its only over areas with no navaids.Sean

I'm creating all my flight plans with FSC and have never had any of these probems. Sorry I know you are trying to help but, if we had to type in our flight plans everytime we flew, I don't think anyone would be flying.I had this problem once with the Level-D aircraft and discovered that it was a conflict believe it or not with FSUIPC (which again you don't need to run this aircraft). I'm not putting down FSUIPC, I'm just trying to point out that you don't need it to fly.I would be inclined to try and reinstall the plane , but after uninstalling, make sure you go in and delete all the files left.

I always type in my flightplans, it's just a few lines with airways, maybe just one or to between the sid endpoint and the star startpoint, whats the problem with that?

Oh it's no problem, I'd just rather be flying than looking up way points, but whatever turns your propeller :(

I see your point, but you only have to add the airways, not the waypoints. That was my point :)

Bob, have you tried re-installing the plane?
