Is ground effect mode modeled?

It doesnt feel like it so I figured I'd just ask to know for sure.

If it isnt, is that some thing that can be realistically modeled?

Yes it is; that's why you get "float" on landing.

I have never really noticed it. Of course my real life flying experiance is with sail planes and being the lift ratios are different it probably aint noticable to me in these powered planes.

I always thought the reason I floated was because I pulled back on my stick to much for my given speed. It never feels like I'm riding the ground effect.

It is modeled.

What's a "ground effect" anyway?

Taking a pee and puting your toe in a electrical socket?

Ground effect is more lift provided by the airfoil being very close to the ground and causing more pressure underneath the wing.

Ahh.. sort of like when you blow a fan against the wall and the wind bounces off from it and hits you again..??

It's mostly due to a reduction of induced drag.
