Fix Attempted - Please Confirm in New Build Wind shifts in latest builds

[damian]

Can you provide reproduction steps or isolate when this happens? It's likely not ASFS wind setting that is causing it, since we've fully redesigned the smoothing and many others things now to rule that out. Perhaps another add-on is causing a change of something, a switch of preset, or other weather configuration change. Are there any other weather changes that occur when this happens? What other utility add-ons are installed? Is there something reloading a flight plan automatically, or are you doing anything in the ASFS UI that may be triggering an ASFS refresh? Does this accompany a weather download?

Can someone catch this on video with the dev mode weather debug window up showing the ambient winds?

Any other hints or help reproducing or understanding how/when this occurs is appreciated. I've exhausted my efforts at identifying any issues, with significant testing and guesswork, until now.

Here is a new build with redesigned wx control script wind smoothing logic. This should prevent anything larger than about 2kts/deg/sec during constant altitude wind condition changes except for when in the surface layer (which is subject to gusts). Depiction smoothing rate has a limited effect on this (min 1 deg/kt/sec, max 4deg/kt/sec).

Note that MSFS applies vertical wind changes/smoothing itself. ASFS is doing the horizontal smoothing based on ambient interpolated conditions and should match the conditions screen and debug wind info when flying at a constant altitude near the normal wind layer altitude indexes (e.g. 30,000ft). When descending or climbing, variations and potential cross-boundary shear events are expected but winds should settle and match once a constant altitude is again achieved.

Also note that applying weather, option changes, loading a flight plan, or any other "refresh" action from ASFS will bypass smoothing as intended. Smoothing is for uncommanded changes through conditions changes or geographic location changes per normal flight progress.

Update 121524 (SU1) B9115 (1.0.9115.31736)
- New wind smoothing processes in weather control script for smoother vectorized wind conditions changes targeting approximately 2 kt/deg/sec (depiction smoothing rate setting has a limited effect)

Please let me know your results. Thanks!

Hi,
Also got wx shift during crz in v9115, please see log,thx.

Hi,
All went well on my flight today with v9115. I have no other weather related add-ons installed and MSFS2020 turbulence settings at low.

I keep getting this too, mostly during climb or cruise, not always fully catching the hows and whens, just a sudden overspeed and a/p disco OR a sudden loss in speed until I hit A-Floor... (Fenix)
I was able to record it the last time it happened. Not sure if this helps:

PS: shortly after this video, the wind changed again from head to tail, causing a significant loss in speed.

Add me to this, happening at cruise without any sim interaction but mine is with the PMDG 777. I actually just posted in the pinned post as well.
Latest production release of ASFS and MSFS 2020 and same behavior as others. Sudden wind and barometer shifts, clouds popping and causing huge altitude discrepancies and overspeed/stall conditions.

 

[damian]

So this looks like all depiction is stopping from asfs? Any yellow triangle warning icon near connection status? Log exports after this occurs would also help.

 

[psolk]

My logs attached
I hope this is what you need. It was a long flight!

 

[psolk]

Here are my logs from my ongoing flight. I think I have had it happen 6 times in the last 30 minutes. It's making the plane almost unflyable unfortunately.
KEWR/22R N0487F330 DCT MERIT DCT HFD DCT PUT DCT EBONY N469A SAXAN/M084F330 DCT 53N050W 56N040W 59N030W 61N020W 62N010W/M084F350 DCT GUNPA/N0483F350 DCT ZOL DCT RADIS DCT KOSEB/N0477F370 DCT BINKA DCT DESEN DCT MAKAL DCT PARAK DCT OBLAK DCT NISVA DCT OTKOK N131 RODIP DCT BELGI UN131 KULAR UT39 TOMBI DCT IDAKU L35 PIKOG L609 ZUKKO AMOS1A LLBG/26
Winds went from something like126 kt tail to 0 to 148 kt tail to 85 kt tail., the plane was all over the place...
Logs and videos attached. Apologies, I wasn't in Dev mode, I will try to catch it in dev mode next time, I missed that.

[damian]

Thanks for the continued logs. I am hoping to get some confirmations of the following

1) Is it ONLY winds or is all weather losing depiction temporarily/intermittently?
2) If you're getting this often, please run with the dev mode weather debug screen open and record the event which would really help in identifying this issue
3) When you encounter this issue, please get a coherentGT log (instructions below) after pausing your sim:

• Open browser and go to http://127.0.0.1:19999
• Find the item that shows ToolBar.html (or TOOLBAR_REWORKED for FS2024) and click it
• Click the CONSOLE tab button (right side, near top)
• Click the LOGS button (under CONSOLE tab button)
• Cut/paste the log data or send the screenshot of this log (make sure it is large enough to read).
• Click the ERRORS button (same location)
• Cut/paste/screenshot the info shown there too

Thank you!

Hi Damian. 1. I hope you don't think you get the holidays off. I would like this resolved ASAP...

I'm KIDDING!!! Happy holidays to you and yours!!!
1. It looks to be winds and barometer. I don't see temp reset to 15 or anything like that but the winds will disappear/shift and the plane will suddenly be a few hundred feet higher or lower.
2. When you say record, there isn't a log event function or anything like that, you mean try to take a recording like we've been doing with that window open? I think I have two here but it is always while recovering from the event... I hear the A/P alarms go off and grab my phone to record... Not sure how to try and "catch" it real time...

3. Will do the next time I replicate. I'm assuming Toolbar is the relevant file in 2020 as well?

Happy Holidays!

This should be fixed here: https://hifisimtech.com/asfs-su2-update/

Let us know your results. Thank you!

 

[JerryJet]

Let us know your results. Thank you!

One flight with the 9126 build. Zurich to London @ FL320. No issues.
Thanks for the fix.

Hi,
First of all thanks much for your efforts and new built. However, I faced exactly the same wind shift issue with version 9126. It didn't happen on version 9115 (I had 3 flights with that version).
Wind shift happened exactly same as before:
When cruising at FL360, initially wind was correct. Then, within 2 seconds, wind went 000/00 and after 2 seconds start blowing exactly from opposite direction with same speed. Stayed incorrect direction for around 4-5 minutes then same changes happened from incorrect direction to correct direction. I noticed that the debug screen shows correct wind all the time. At the end I had to change passive mode in order to complete my flight. Otherwise it was impossible to control the aircraft with all these wind direction changes.

I will revert back to 9115. Is there any technical difference between these 2 versions in terms of wind direction handling/injection?

Log and screenshot with MSFS wind and ASFS wind debug screen attached.

Edit: I also noticed that the direction always changes to opposite direction of correct one (in above case it was from ~350 changed to ~160) and speed remains same.

 

[hifly]

I just completed long flight in the Horizon B787-900 and had no issues, but the winds at altitude were less than 60K the whole trip so may not have been a fair test. When I encounterd the issue initially I was in the jet stream with 170K+ tailwinds. And yes, it seemed as though the injection just stopped and ASOBO default settings resumed (baro and winds). I noticed your solution for 9126 was to keep winds maxed at below 149K, but some of us do enjoy riding a fast jetstream once in a while. Thanks, Damian for being attentive to this issue even though it is holiday season.

Hi @damian

Thank you for the latest update and happy new year!

Regarding the new winds depiction limit in B9125. Does this really mean ASFS will no longer depict winds aloft in excess of 149.9 knots?

If that is the case, can you please consider adding a user option to disable the new limit, so that those of us who wish to do so can still depict winds in in excess of 149.9 knots?

I understand doing so may come with unintended wind shifts (is this a MSFS bug?) however a hard 149.9 knot limit will significantly impact flight planning. Especially across the Pacific, where the jet stream is routinely moving at 180 to 210 knots (for example today).

A -50 to -70 knot disparity between planned winds and depicted winds (if the new limit really is 149.9 knots) is too much to accept from a flight planning standpoint for those of us who routinely fly transpacific or in other areas with 150+ knots jet streams (e.g. rhe Atlantic during the winter months).

It is imperative that we can continue to depict the actual reported wind speed in ASFS and MSFS, without being limited to 149.9 knots.

I am currently using B9115 and I have never encountered any wind depiction issues and I routinely fly long sectors in areas with winds exceeding 150+ knots.

It would be a shame to forced to remain on B9115 and thereby forgoing any of your future ASFS improvements/updates due to this newly imposed wind speed limit in B9125

Any insight and clarification would be greatly appreciated.

 

[damian]

We're still working on this, but we have determined that many wind shift events were caused my MSFS forcing wind unexpectedly to zero when a value > 149 knots was populated. The MSFS UI doesn't allow input of over 150 knots, and we are using the UI system to control weather including winds. This depiction anomaly may be influenced by recent MSFS2020/2024 updates. Whether current MSFS can actually depict > 150 knots correctly or not is being investigated, and if we can do it, we certainly plan to allow this, and if not, account for this more realistically by limiting data/briefings/all wind data in the ASFS engine to the same wind speed. In short, this is all being worked on and as usual we hope to make this as good as possible.

See the other thread where I responded to you, as it's not effective for us to duplicate conversations across multiple threads. Thanks!

Hi Damian. Since you replied another user's question in other thread, could you please check the issue if possible? Wind direction shifting is happening on version 9126 but not on version 9115. I tried multiple times. It doesn't matter the speed of wind, it's direction.

 

[LiquidDinosaur]

Is this an Active Sky FS issue, or something else I should be looking into?

At the start of the clip, winds shift direction nearly 360° around and causes a stall.
At 6:20 in the clip there is an overspeed event - a sudden 180° change to a headwind and then a shift back to a tailwind.

(MSFS 2020, PMDG 737-800) ASFS 9115

This happened twice. I restarted the flight after the first occurrence. This clip is form the second flight, after restarting, and just let the plane fly itself through the wind shifts to recorded the results.
