How is Ground Effect modelled in DCS World PFM ?

[Anatoli-Kagari9]

Professional Flight Model appears to be the highest in the rank of detail and accuracy when it comes to flight modeling in DCS World.

 

I wonder if ground effect is modelled at a single reference point for the whole aircraft or if destinction is made between, for instance, wings and the tail surfaces ?

 

When during landing, right above the runway and bellow one wingspan of height the ground effect starts increasing, does DCS PFM take into consideration the peculiarities due to it's effects over the main wings and the stabilizers / elevators, expressing itself also as a pitching moment ?

Yes, and this effect of trim change is the most noticeable for MiG-29, and it was caused so much whining from some players. We even had to perform a detailed CFD research to investigate this matter and prove that this effect is actually very pronounceable. 
Fast pitch trim change near ground is really inconvenient if you have no acceleration feedback as in RL. It requires understanding of the process and a lot of anticipating to master touchdowns.

Yo-Yo, thank you for the confirmation !

you know if you look into the whole ground effect thing, and airliners flying 100kts above max speed, it quickly... oh wait, i forgot this ain't conspiracy anon!
