Flaps should always be Full for landings, ground effect should never happen as it does not occur IRL.
Trim works through the FBW by holding AoA once set in PA, it is an exact number in accordance with aircraft weight including fuel.

Almost always... Well, the real world part has been extensively explained by Lex.
bbrz was trying to narrow down this reverse ground effect bs...

Where did you get this info from? Looking at the wing span, loading, its position, flaps/flaperon size and deflection angles, it's rather easy to calculate that there is ground effect.

That it isn't noticable/effective during unflared landings, where you are descending rapidly through the ground effect, is a different story. Maybe even the FBW masks it.

No.

I am referring to the Hornet, does it effect the aircraft adversely on approach...no!

Erm, that's exactly what I said. With the no flare landing technique, it doesn't. If you try to grease her on with a high power setting you would most likely notice it.
Same goes for the DCS version, since the required AoA and thrust is lower in ground effect.

Not my video so I hope this is cool to post here, but captures what I’m describing. Several pretty good approaches. If you watch the indexer just prior to touchdown it goes into the red fast arrow every time.
