Thinking of abandoning the PMDG 737 NGX

Recommended Posts

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.

Have you considered the possibility that this behaviour might be realistic? 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.

After PMDG 737 NGX, is there anything else to fly ?

 

Son, you will put yourself together, and fly that thing. period !

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.

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.

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?

Hmm...you should give FSUIPC a go. What weather addon are you using?

 

Tried my registered copy of FSUIPC, no change. OpusFSX

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.

Try out ASN  ^_^ Had the problems with REX, though not big enough to be an issue, it was still annoying though.

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.

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.

Nope, never experienced that porpoising effect...

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

Watch the yoke in the video, its not head movement.

 

When I use spot view the plane's nose deviates radically up and down, with both Opus and FSX air turbulence. 

 

I have to get going on my video so I make myself clear.

It looks like you had a single-digit wind there.  I use the 737NGX and OpusFSX and would never see those sort of oscillations.  Something wrong with your settings I think.

In Fsuipc winds section put a tick in variance.that stopped it for me.

Opus like ASN, you do not use fsuipc weather settings. I think Capt Speirs has an issue with his Live Camera settings in Opus, and would be best to ask Stephen @opus. he will help.

So the OP should purchase another weather engine because his settings maybe incorrect ?

Quoting other similar reports is pointless. If you read those threads you'll find very similar responses, mostly suggesting it's weather engine related. Do you think the people who are telling you they don't have this problem are lying to you?

 

I'm not saying you aren't having a problem but I don't think it's related to PMDG's simulation.

Your weather program is causing this. Adjust the weather settings . Playing god with the weather has nothing to do with it. Weather programs can be very unrealistic. Leaving a beautiful and realistic aircraft like the NGX over a problem from your weather program tells me you don't want realistic or understand which add on is more realistic. That aircraft is way more realistic than your weather program.

What does the camera settings have to do with the yoke moving in and out and the nose bobbing up and down? I use the same settings on my PMDG 777 with no issues. I am not trying to be sarcastic, if indeed the camera settings are an issue I would be grateful to get rid of this annoying behavior.

 

BTW; I tried to make a video and I couldn't duplicate it...grrrr, figures. Tooth stops hurting as soon as you get to the Dentist syndrome.

Because LC is tied into the weather engine. Check your DOH setting and Bump aircraft in DHM dialogue box. Also make sure you are using default weather settings in Opus weather configuration box.

Also, make sure you are using the latest beta version. One was released yesterday.

Even though your 777 does not have this issue, which may have different LC settings, you need to check DHM for the NGX to at least rule it out. In particular DOH and Bump.

DHM and Bump have nothing to do with the aircraft going up and down.  You can see that the yoke is going back and forward in the video, either to compensate for nose up or down or to maker the nose go up and down.  As it's not the Capt's aircraft it doesn't make any different.  It's the weather engine or settings in Opus or FSUIPC.  Since day one for the NGX I have used Active Sky in one version or another and never had a problem with porpoising.
