April 9, 201412 yr I really like flying the NGX, I just can't put up with the constant Porpoising/Bobbing in AP climb with head wind anymore. I understand from searches that there is no fix, anyone? oops, wrong forum. Ric Elmore

Real autopilots aren't perfect and will also be disturbed by atmospheric changes. Sometimes I find switching to VS mode in the latter stages of a climb helps smooth things out.

April 9, 201412 yr After PMDG 737 NGX, is there anything else to fly ? Son, you will put yourself together, and fly that thing. period ! Regis Regis Biassala
April 9, 201412 yr Commercial Member Sounds more like a weather add-on issue than an issue with the plane, honestly. That's what the case is most of the time, anyway. Try flying it without weather to see how it does. Kyle Rodgers
April 9, 201412 yr I don't fly it much (more of a GA flyer) but, I don't remember ever having that problem. Seems to fly quite nicely. Gregg Seipp "A good landing is when you can walk away from the airplane. A great landing is when you can reuse it." i9 64GB RAM, GTX-5090
April 9, 201412 yr I fly on AP all the time, have no weather add-ons and don't experience that problem...so I don't think its the plane itself but rather something in your configuration and/or setup. However, if you're mind is made up, what plane are you going to move to? The PMDG 777? Ralph Freshour www.GMTPilots.com
April 9, 201412 yr Author Hmm...you should give FSUIPC a go. What weather addon are you using? Tried my registered copy of FSUIPC, no change.

Sent from my iPhone using Tapatalk I will have to make a video, if this were real, we would need lots of "Airsickness Bags". I have done some research and this is not isolated, PMDG even mentions it in their manual to turn off air turbulence. I got the NGX for realism, not to play god with the weather so it fly's right. This video (not mine) is actually mild, it gets much worse. Ric Elmore
April 9, 201412 yr Try out ASN ^_^ Had the problems with REX, though not big enough to be an issue, it was still annoying though. Thoriq Kamaruszaman, Potato Flier READ THE MANUALS.

PMDG don't have a turbulence problem, at least no more than any other FSX addon developer. PMDG recommend turning off FSX turbulence because it is modelled in a very strange way. I have turbulence enabled as it happens and don't find any problems with it, as long as I don't use FSX weather. FSX weather is really the cause of the problem and using any addon weather engine will improve things dramatically.
April 9, 201412 yr Commercial Member Indeed, like mrtk said you should try get Active Sky Next. I use it and I've never had this kind of problem with it... ASN turbulence seems to be just fine with PMDG 737NGX too. Regards Joona L
April 9, 201412 yr Nope, never experienced that porpoising effect...

April 10, 201412 yr opus has head movement effects and such built in, and turbulence looks like that to me I use it and love it try flying without opus and see if it does it with stock weather Shane Strong: Aircraft Painter, Scenery Designer See Sim Scenery Makers on facebook for our Current Airport CYZF Beta Tester SimAddons Check out my LiveATC.net feed CYQI and Supporting Flightaware with ADS-B Feed
