Ground effect in IF?

1

Anyone have a breakdown on which IF aircraft have ground effect modelled vs those that don’t?

And also perhaps, anyone’s opinion on which of the aircraft with ground effect modelled have the most notable vs least notable ground effect during landing? (I did a search before asking this question)

(side note: I had a question for AI. Maybe I’m ignorant. AI didn’t seem too impressed with my question:

Is the Mach speed limit for subsonic aircraft and the cause of ground effect during landing, both tied together by the average random thermal molecular velocity of air? In other words, assuming both the mach speed limit and ground effect are scenarios where air compression starts to become significant, is that because local density of air mass in both cases gets “corralled” faster than the thermal velocity’s ability to dissipate that bunching up of mass, as distinct from say, the non-compressibility of air around an airfoil when far above the ground and well below the speed of sound?)

As a pilot, I certainly had an unavoidable feel for ground effect. But I never felt comfortable with the explanation as to most fundamentally why. My question is at odds with, for example: Ground Effect: Why Your Plane Floats During Landing | Boldmethod

Anyway, it made me think more about where I feel ground effect in IF, and how I respond to the differences between IF aircraft.

Why was the first thing that came into my head after reading “ground effect”

So, in the F1 case you’re trying to hug the ground more firmly but with an aircraft it’s keeping you off the ground longer (opposite of hugging the ground)? I mean, in your image, it looks like an upside-down wing.

Yeah, exactly !
The car generated more downforce by pulling itself downwards with ground effect.
So you get better turns and- prevent the clr effect . . .

Aircraft spoilers are perhaps a bit like adding on a temporary upside-down wing (like the F1 has permanently) onto the main wing.

Any opinion on what IF aircraft has the most noticeable ground effect during landing?

It all depends on how you land. Ground effect can still be “small” just because you slam the aircraft into the ground.
But let’s say of you land realistically and methodologically let’s say that the newer aircraft especially would win this. The E jets do have this quite strong as well as the A220.

Of also the newer wide body aircraft will have this more. Like the A330 and the B777. To add also add the A380 as that plane is a monster.
