ActiveSky and Fenix V3

[danhenri]

Hello, do you confirm that there is a kind of incompatibility between ActiveKy and the last update of the Fenix ? As other users (see Fenix Discord), I see no effect of turbulence on the plane, especially when it flies through clouds. Thanks for your answer.

You need to contact Fenix regarding this.

On Discord, Fenix says the same thing : contact the developpers ! It helps a LOT !

That is what "Aamir"has written :
"Again, at this time, I believe we're one of the only airliners using the inertia tensor. We are not going to stop using new features because third parties aren't compatible. I've invited wx devs to reach out and get in touch with what it is they're doing, but I also think a lot of the statements here are incredibly hyperbolic as I took the airplane out myself last night in Realistic Native weather and it was bouncing around all over the place. You are also free to roll back to V2, or indeed just stop using it, but I'm sorry - we will not really be adjusting the FM until we understand what these weather apps are doing that is different to the native weather (again - quite clearly in our own internal testing), how they are inciting turbulence, or whether they've even done any basic investigation on the inertia tensor stuff or whether the response is as plain and simple as: "works on other stuff", and even then it's quite unlikely that we will adjust the FM to make it compatible with third parties when working fine with native (unless there's a very good reason why)".

Perhaps it would be a good thing if developpers could speak to each other ?

 

[danhenri]

Are you intended to contact the Fenix's devs ? They are open to find a solution to this...

Interesting. I had noticed ASFS showing different levels of turbulence, but no movement in the plane. I guess that's why. Ugh - thanks for posting.

I checked whether creating Microbursts or Windshear did anything in the V3 Fenix and neither affected the airplane at all.

We’ll add this to the investigation list. As you know, ASFS turb has worked on all aircraft for years and this is the first time an incompatibility like this is seen. We control forces in sim using the documented SDK. If they have bypassed forces and using external flight model control, a specific integration with that aircraft would be needed. It’s not out of the question but will require cooperation and work in both ends, most likely. We are always open to integration with other devs. So in short, we’ll try.

Thanks for looking into it Damian. From the quote above and other things on their Discord, they seem pretty sure of themselves that their use of the inertia tensor is original and within the SDK, but that they are willing to discuss things with other devs. Please let us know if there is anything that we can do to help. They are already aware that ASFS does not work well with the V3 Fenix.

Just an update. A known MSFS2024 bug which breaks/disables rotational velocity commands through standard simvars when Interia Tensor is enabled is what is causing this. This is one of the first aircraft (maybe the first) using this Interia Tensor. We are investigating a new experimental turbulence model to control turbulence without using rotational velocity commands.

 

[damian]

We have a test build with the new experimental turbulence model:

https://www.mediafire.com/file_premium/xxosqs4hu7u129t/AS_FS_Install.exe/file


Update 110926 - B9809 (1.0.9809.28652)
- Updated formatting of PMDG uplink export for proper waypoint naming convention compatibility
- Added experimental turbulence model which should work with Fenix V3 and other aircraft that enable the Inertia Tensor – Enable this via Options/Simulator depiction options
- Lowered the minimum depiction wind limiter speed to 75 knots

Feedback appreciated.

Thanks for the timely update! I’ve just downloaded and tested this version—the realistic turbulence effects are back. Using the default settings, I’ve noticed that at low altitude—especially when in the landing configuration on short final—the turbulence affecting the roll axis feels a bit "stiff," with the aircraft’s response coming across as slightly excessive.

Thanks for the feedback. This aircraft probably could benefit from some ASFS turbulence roll setting adjustment to get an ideal effect. Please try this and let me know your results.

Just tried the latest test version with the turbulence for Fenix v3, and I get really stange and sudden updrafts without any change in wind ...... The plane just suddenly starts getting lifted upwards with a significant climb rate. this is 10116 ft/min.... That's not even achievable when going 260kt and a pitch of about 17deg., there's some force just lifting the whole plane up... Happened twice on the current flight.

Hi, Just tried your latest version, PMDG B738 sudden updrafts up from my FL360 to about 380 for maybe 5 to10 seconds then back to normal, seems to be at cruise only, don't remember it happening on climb or descent, BATC telling me I'm at the wrong FL lol. Happened multiple times, shutdown ASFS didn't make any difference, switched MSFS 2024 to a preset weather and then back to live without ASFS but continued to do it. The next flight I didn't use ASFS and it was fine no issues?
Thanks so much
Love your work!

I just completed several test flights, using FENIX A32X, with ASFS set to default, and the following main problems occurred:
1. During the takeoff and climb phase, the autopilot cannot follow the guidance and the aircraft's pitch angle continues to increase, requiring manual disconnection for recovery. This phenomenon still occurs after reconnecting AP;
2. During high-altitude cruising, turbulence in the clouds caused severe oscalation in the autopilot. Even if the autopilot was disconnected in time, it could not recover, and the aircraft's attitude could not be maintained;
Possible solutions:
1. In view of the increasing pitch angle during takeoff and climb, reduce the updraft/downdraft rate slide to within 100ft/m (default 500ft/m);
2. To prevent the aircraft from losing control due to high-altitude cloud turbulence, reduce the cloud turbulence intensity to below 30 (default 50).
Test flights and reports will continue in the future.

Thanks for the feedback. Could you replicate this and confirm that turning OFF the experimental turbulence model resolves the issue when it is happening?

 

[damian]

Here is a new build addressing the issues reported. Thanks for the continued feedback!
