Having watched a youtube video on the new ActiveSky software this morning. I did at the suggestion of the presenter increase my AS turbulence setting from the default 50% to 80%. My turbulence setting within MSFS is set as realistic.

I then identified an airport (using windy.com) where there was significant clear air turbulence - in this case the airport I selected was OEPA.

Using FSiPanel, I set up an approach to RW34, positioning myself so that I arrived with left hand vectors. Active Sky live weather was selected.

Then I tried the flight in the Fenix A320 - it handled it beautifully, and I was delighted to see the ailerons kicking in and out on both wings - so realistic. I have never seen any aileron movement in the Fenix A320 during flight before, and I was able to land satisfactorily.

Then in almost identical conditions, I made the same approach in the PMDG 737 . The aircraft just rocked from side to side, banked too far, and absolutely no deflection of the ailerons. Impossible to land.

So, I guess the setting of 80% turbulence in AS is too high, especially for the PMDG 737-800, so need to find the 'sweet spot'.

Can anyone shed any light as to why the PMDG 737-800 ailerons did not deflect at all? They were kicking in and out all the time on the Fenix A320, so I would have expected some deflection on the PMDG 737-800.

Happy Flying

From my recent experience the PMDG auto flight system handles turbulence and variable winds poorly compared to other airliners in MSFS... It teminds me of the way airliners in xplane behave under variable wind, with or without turbulence also set...

My ASFS Turbulence effect scale to fly the PMDG 737 is at 15 with MSFS Turbulence to REALISTIC. This settings avoids the excess of over banking for me. Didn't try MSFS turbulence in another setting though, but, If I'm not mistaken ASFS recommends to set it to LOW.

Were you manually flying or under autopilot ?

Because aside from the realism setting, the behavior you describe is basically the difference between fly by wire and the old hydraulic aileron control.

Fenix also recommends to set it to low.

At the time of the behaviour that I reported with the PMDG 737-800 - I was on autopilot - but the same situation was with the Fenix A320 - when I was also on autopilot.

It worked brilliantly with 80% AS turbulences setting with the Fenix A320 - it was the PMDG 737-800 which had erratic behaviour

I suppose my question is - that if Fenix and PMDG suggest that you should set the Active Sky turbulence to 'low' - why does the Fenix handle 80% turbulence really well and PMDG does not?

Second question (which I am repeating from my first post) is that PMDG (which I love BTW) has no aileron deflection in the same environment - where Fenix A320 does.................Why?

It seems like despite everyone's efforts, ASOBO/MSFS's approach remains the main issue. I think the "LOW" option is more acceptable compared to real life.

 

Another important factor to consider is the size, weight, and type of the aircraft. From the perspective of a real pilot who has flown Airbus and Boeing, I can say that I prefer the Airbus ride due to its different A/P, modes, and the significant difference in how FBW handles.

 

While I agree that there is a noticeable difference between the flight dynamics of the Fenix A320 and the PMDG, in reality, it's not as significant. However, since it's a game, it can't perfectly replicate a real airplane. It's important to note that even a level D simulator is not exactly like a real airplane. PMDG, compared to FENIX, requires more attention in many aspects.

 

Lastly, I believe that the 80% figure is too high and open to interpretation.

I've had the same problem with the 737-800. MSFS turb set to LOW, ASFS turb set to REALISM mode (whatever that is, I think scale of 60). It would be bank angle alert and AP disconnect all flight long. Happened only once luckily.

100% correct. 

In my settings, I find the best solution is to set MSFS turbulence to "LOW" and ASFS to 10 from the default 50. It's a compromise, but it reduces the rollercoaster ride effect. I'm concerned that ASOBO won't make any more changes. There are many people who enjoy this unrealistic behavior, such as jerking flight controls thinking it's normal. Even with these conservative settings, I often see small airplanes behaving as if there is moderate to severe turbulence in low crosswinds or light turbulence. I believe this is what most people consider appropriate, regardless of the actual facts.

I have same settings as you, Low in MSFS and AFSF 10.  Seems to feel realistic to me, and I have many hours flying commercial as a passenger.

Try RealTurb. They did a fantastic job on p3d and the same can be said for the msfs version. I turned off the AS turbulence and left realturb to take care of it in stead.

Whats your setting in Realturb? Thanks
