April 9, 20179 yr Hi, This is consistent here when I fly in a stormy weather (Thunderstorms in the area) and in general, stormy unstable weather which will bump the airplane. Airspeed becomes really unstable and will jump up and down to the RED scale (airspeed too low) and subsequently the autopilot disconnects. Maybe it is the way it is designed? I am using AS16 + ASCA and scaled down turbulence effects (both cloud and wind) to 15 to try and see what happens. It did not help, and I had to hand fly the A/C until it got out of the stormy area or altitude. also EZCA effects canceled in lieu of the PMDG 744 built in effects. Any ideas? suggestions? Tx Benny
April 9, 20179 yr How fast are you flying when it gets that bad? Typically you should steer clear from thunderstorms as much as possible, but in the event you need to go near one turbulence penetration speed (Vb) is typically best. The autopilot is just another tool at the pilots disposal, don't be afraid to have to hand fly the airplane. Hand flying in turbulent conditions is not abnormal by any means.

April 9, 20179 yr Author Usually after takeoff when you are still relatively slow. A good example is VNKT (Kathmandu) which at this time is mostly rainy and thunderstorms around. In fact I am searching for thunderstorms with AS16 and going there. As long as you are in the storm zone and altitude (so to speak) I get this tripping of autopilot. Indeed I hand fly, however cannot enjoy the view around while doing that.... Thanks Benny
April 9, 20179 yr Full names in the PMDG forums please Benny. Dial back your AS16 turbulence sliders. The effects are unrealistic when set at the default 100%, as described in detail in the Introduction document. Most mine are set around 20-25%. Dan Downs KCRP
April 9, 20179 yr Author Dialed down turbulence sliders to 15 actually but it is there with 15, unless not all dials were dialed down.... I am going to test this with even lower scale and see what happens. Thanks Benny Kupfer
April 9, 20179 yr With moderate settings I've never had the A/P trip due to turbulence. Maybe you have a problem with controller calibration or null zone setting or noisy controller sending spikes. There are options in the PMDG Options menu to minimize controller interference with A/P... as described in the Introduction. I assumed you read the Introduction and made those settings for your configuration. Maybe not? Dan Downs KCRP
April 11, 20179 yr Author Update: Moving AS16 sliders (there are three of those related to turbulence) to zero, helped a lot, but the problem did not go away completely. I would say improved about 80%. Maybe it is the fact that I take off from a high altitude airport, 4200ft)? At the moment I will continue testing in different environment. The PMDG option to minimize controller interference is ENABLED. Thanks benny Kupfer

At this point, I'd be willing to bet that it's your controller being out of calibration, an axis not being centered, and/or the potentiometers being old/bad. 9 minutes ago, BK said: The PMDG option to minimize controller interference is ENABLED. We have some tuning, but you may be better off with the setting that basically tells the AP to ignore your hardware entirely while the AP is on. Kyle Rodgers
April 11, 20179 yr Author OK. As far as I understand this option it should be set ENABLED. Right? Or should it be put to DISABLE? I am a bit confused as to the correct state it should be at. Thanks Benny

April 11, 20179 yr Disable enhanced turbulence and thunderstorm effects. Also make sure "wake turbulence" slider set full left ( none ).

April 12, 20179 yr rFurther to my post above, I believe the suggested values for the FSLabs A320x are probably a good choice, namely: Active Sky 16 Max Cloud Turbulence: 20% Max Wind Turbulence: 20% Turbulence Scale Effect: 10% Enhanced Turbulence: Off I also set: - Wake turbulence strength: full left ( off ) - Maximum downdraft and updraft rate to 500 fpm - Realistic thunderstorm up and downdraft rate to Off José Monteiro Flying gliders since 1980 Flightsimming since 1992 AMD Ryzen 5600x, 32GB RAM, GPU Nvidia RTX 3060 Ti 8 GB, 1 TB and 500 GB nvme2 SSD drives, HP 27" 60Hz LED monitor @ 1920x1080, T16000, Hotas from old X52 Pro, Saitek Combat Rudder Pro (2010 model)
April 12, 20179 yr Author Well, The above from jcomm and pcubine and scandiinavian13 indeed helped and resolved the problem. Thanks a lot. Now I can look outside and see view.... Benny K
