Aircraft turns right mid air

Recommended Posts

Hello,

I have a problem with my PMDG 777. When im enroute at some point of the route it just starts to veer to the right. I dont know whats wrong with it, cause AP is engaged and running fine. If i reselect the waypoint in the cdu it realigns on the magenta line but after like 1-2nm it starts to veer again.

May you help me, thanks!

What weather program are you using?

im using OpusFSI

 

Disable the wind aloft. Opus has been noted for having a sketchy upper wind model.

Where can I do that? 

 

Not sure. I've never used the program. You could also just not run the program for a flight to verify.

Yes, i tried 3 flights today without Opus (TXL-CGN-TXL  in 737, had the same problem, and currently in 777 from LAX to SEA) and they all worked fine, I reinstalled Opus already. I will have a look for this setting and will reply, thanks!

There is 48kn crosswind in the image. Did you try entering that wind info for that leg in the FMC and see if the AP compensates and levels.

This won't solve it. Entering the wind into the FMC is only used for fuel/time calculations. A constant 48 knot wind is not going cause roll like that anyway.

It might, I had a similar problem a while ago witht the PMDG NGX going off route. Entering the wind info in the FMC leveled the plane. That's actually how I learned about that page in the FMC I didn't know existed.

With respect, it won't. What happened in your case was merely coincidental.

 

Firstly, again, this function only serves fuel/time predictions.

 

Secondly, in a physics sense, a constant wind will not cause any sort of moment on an aircraft flying through it. If the opposite were true, planes would be doing flips when using the jetstream, or flying through it.

 

I get that it probably makes sense to you, particularly because the issue resolved when you entered the wind, but from a software and a physical sense, it does not.

If that's how you found out about the FMC page you never read the NGX Introduction or did Tutorial 2. A crosswind has nothing to do with the NGX banking. You were doing something wrong. The NGX was being operated incorrectly.

Just out of curiosity, did you, by any chance, innadvertedly switch on the fsx / p3d buil-in auto-rudder in the Aircraft menu ?

You are correct, I never read the manual. But I am trying to help instead of judging.

Hi Justin,

 

A few months ago, I had a similar problem only with PMDG 777/737 "left turn in mid-flight", so maybe this help you.

 

Change your motherboard battery.

I've seen the 777 start to turn off course for no apparent reason. It is very rare but it wasn't weather related. I suspected a combination of things including using time compression but it is never repeatable. Last time it happened may have been more than a year ago.... like I said. Rare and odd.

 

I recommend OP not use Opus and if possible invest in AS2016.

 

As for crosswinds....., the airplane is never aware of constant moving air except through reference to the ground.

So, it was definetly Opus. Several test flights without it were perfect. 

I wont ever buy any Active Sky product cause I dont support their price policy.

Thanks so much for being kind and courteous to people who are incorrect, and explaining to them why they are wrong in a friendly manner. I wish that other simulation devs were as professional and well mannered as you :D. Just thought you needed to know that youre appriciated

I'm guess that it has to do with having to buy separate licenses for P3D and FSX if he wants to get AS16. Same as PMDG policy however.

 

To bad for him though. Boycotting a product due to something like that means that he'll have to put up with OPUS problems he had posted about and won't get the other radar and weather/wind integrations that AS16 and PMDG offer.

Your loss, AS16+ASCA is amazing. But just to play devils advocate, following your logic why did you buy a PMDG product since their policy is almost identical? Or is it purely selective outrage?

Keep it civil, or this thread gets put out in the lav cart dump shack.

 

If none of you have been in one of those things consider yourself lucky, but also try to imagine the peril that this thread faces. It's in your hands.
