Extreme wind shifting in P3d V5.1 HF1

[davidzill]

Hello, I am experiencing a peculiar issue in P3d V5.1 HF1. While flying an the Leonardo Software MD-83, I noticed the aircraft was having a difficult time flying autopilot heading hold, tracking a localizer, and flying an Autoland. Basically, although I had selected 'Clear weather,' the aircraft was behaving as if it was fighting both left and right gusting crosswinds, constantly rolling 5 degrees left and right about its longitudinal axis.

I contacted Leonardo developers who were quick to assist. I trouble shot further using PMDG's NGXu, and noticed the turn line was flopping left and right, indicative of severe wind gusts from both the left and right. In other aircraft as well.

I have Active Sky P3D, and it was turned off. EA turned on. Interesting as well when I select clear weather, several stratus clouds remain.

Based on this happening in multiple aircraft, I do not believe this is a bug from a 3rd party developer, I think it is an issue organic to the P3D software.

Is this a known issue, and if so what is the fix for it? Thank you!

@ davidzill ,

Did autoland work with PMDGNGXu (which one?)?

Did you disconnect the Autopilot and hand fly ?

Is it reproducible?

Which airport?
Which approach?

Any screenshots of the PMDG PFD / ND during the approach (wind data)?

What was the ATIS report prior to the approach?

[davidzill]

Yes, ATIS Wind calm, sky clear, 29.92. Although there were clouds. Autoland did work on NGXu, as well as MD-83, however MD-83 behaved as if the winds were stronger. This occured at Flightbeam's KDEN, however happens at all airports. This was the ILS 35L @ KDEN. Select clear weather. No wind data on PFD. This happens every time I fly no matter the aircraft.

I have screen shots of the MD-83 on approach with no wind data

@ davidzill ,

I have FB KDEN and PMDGNGXu

Did the P3DgNGXu have the strong wind problems?

Which PMDGNGXu were you using?

When I use EA On and then select Clear Skies there are no clouds.
Are you sure about your setup?

I am going to do a test now.

[davidzill]

Yes, when in the NGXu there were winds and scatters clouds with clear weather set. Let me know what happens on your flight. At this point my sim is unflyable. I used the NGXu 800SWu

F22 APR Engaged

LOC captured and G/S ok all the way down no wind problems

You might display the wind on the top status line, like Vaughan did.
Then you can see if it is wind shifts.

@ davidzill ,

Could you post the screenshots you did?

A video of one of your approaches?

Did you try the KDTW approach with clear sky as I did in the default LM F22 (my previous post)?

@ davidzill ,

What did PMDG and FSUIPC (mentioned in another post) have to say?

Did they duplicate / confirm your problem?

[davidzill]

Apologies for my delayed response. I found the source to the above issues: Ezdock EZCA camera turbulence effects. So this took time to find this, and everyone should disable turbulence effects in the EZCA control panel. Basically, in order to simulate turbulence effects, EZCA actually manipulates the controls of the aircraft, which causes all sorts of issues: Flying out of trim, s-turning when tracking a localizer, etc.
