[Managed speed issues]

I can also confirm this. Today I flew ibn the A330 Lates build) from LSZH to MMUN and above Greenland suddenly out of nothing (I did not interact with any knobs) managed speed magenta triangle at PFD disappeared, therefore a  new indicated managed speed, also in magenta at the PFD below the speedtape, showed 128 kts. My FMGC stated Managed is 0.81 MACH. I had to choose selected speed 270kts, otherwise the plane would loose to much speed. I played around with some settings (CI, Autothrottle, Thrustlevers different modes, etc). Nothing helped to get back in managed mode, at least the plane di not held it´s managed speed regarding the FMGC.

 

In the FMGC I manually inserted for the next two waypoints 270/ (270 kts). Disengaged Autothrottle again, magenta triangle came back, and went back to managed speed (push speed button) and set the Thrustlevers back to CL and engaged autothrottle again. I can not recall the exactly order of this...but the thing which did help was inserting the 270/ at the FMGC for the next waypoints

 

Managed speed is back again, and the indicated managed speed of 128kts,  prior shown below the speedtape in magenta, disappeared also. So I am back in managed mode at the programmed 270 kts and the plane does hold this speed again.

 

There must be something wrong and I do appreciate if Aerosoft will investigate in this issues which several users seem to have.

 

It is not a very rare one.....it is a essential one because otherwise no one can trust the autopilot managed speed option for long haul flights. That would be a pitty.

 

Can Aerosoft please confirm and investigate on this?

[A330 Elevator shaking]

Me too seeing this behaviour. Yesterday at GCLP decending the pitch goes up and down.....as if the plane is recalculating the decent every few seconds and than aggressivly changes the pith. Also the green dot on the PFD is going up and down above and below a decent decenrate. Very annoying issue. I did not have this so aggressivly with the version 101 in P3D V4.5 HF2. I did saw this behaviour there too, but way less aggressive as now in P3D V5.

 

There must be something wrong.

 

Framerates above 30 in VR and above 60 without. ASP3D Wind speed lowered a lot to check if this was the cause. Now influence on this behaviour.
