Wake turbulence simulation

[dcs76]

I think the wake turbulence simulation is not working as one would expect it. Wake turbulence creates vortices at the wingtips which descent downwards behind the aircraft until about 500 to 1000 ft below the aircraft within 30 seconds. As the tvortices turn clockwise on behind the left wingtip and counterclockwise behind the right wingtip, the turbuences create a downwash directly behind and below the aircraft and an upwash on the outside of the vortices.

 

The result should be that an aicraft trailing on center line should experience the downwash only and should descent when not correcting for the effect. When flying behind and below the wingtips of the preceeding aircraft the trailing aircraft should roll towards the leading aircraft.

 

It seems that causing a roll towards the leading aircrafts flight path, the trailing aircraft is pushed further out.

Also the wake turbulence effect is experienced too much when flying behind other smaller fighter jets. There should be slight effects only (buffetting, small roll effects). Instead the effect is as if the leading aircraft was not an A-10/F-18, but a 747.

I am sure ED knows how this stuff works, isn't it a work in progress feature?

I haven't found that. In the I-16, behind another I-16 at around 220 kph, I just experience a small "bouncing/swaying" of the nose with a little push downward. In the spitfire, behind a B17 at 350kph the aircraft rolls quite violently.

But I haven't tested this thoroughly yet . . something more to look at though.
