not if you land them with a stable approach at the correct airspeed and flare correctly

float is what happens if you are too fast, reduced drag and increased lift is like landing 101, no wonder you have so many problems.....

Yeah you won't float if you approach and "land" that poorly. One of the worst I've seen in a long time. Way offset to center line, way too high and horrible 448 fpm.

its different in VR, that ground is really coming towards you, and there's no second chances.

and nope, 144fpm, it even says in the video.

On the VR topic, put the headset on a friend this morning.

This afternoon he spent $1500 on PC upgrades and ordered a headset.

It is that good.

Occurs in all kinds of aircraft, speed not a cause. Even with heavies can float forever.  Watch the recent video by Flight Deck 2 Sim on youtube in an Airbus Beluga. Thing doesn't want to touch down. Major flaw in flight model.

Really flew into Sydney one real 767 plane floated 1/4 runway before pilot aborted and did go around, you could feel it the whole way. Good sims dont take into account bad users.

Only happens when they fight strong crosswinds not when it's calm that's why you felt it.

If what you are describing is

It happens even in perfectly calm conditions if you don't bleed off enough airspeed in the flare to cut through the ground effect, problem in chair not in computer.

The other one of these I see criticised all the time is pulling to the left in the cessna when you whack on full throttle from idle FSX style, this is also realism over game playability, and not problem with the plane, flight model or computer.

No it doesnt. In fact if you dig back a year or so, there was complaints from the community about the planes slamming into the ground, because there was no ground affect, Laminar admitted there was an issue, that the down wash was passing through the ground and not being reflected back up. They fixed it. So your are opposing the rest of the community on that matter and real flight dynamics. I am sure our friend @mSparks would remember that one. and if you bother you can find video demonstrating that affect.

A month ago or so I tested the effect.

It looks to me it has now more to do with the sudden reduction in relative wind component on the last 30 ft or so under strong wind conditions.

All of a sudden you get from what is sometimes a 30 knot wind to something like 6 knots... This abrupt change causes the aircraft to loose a lot of lift in XP, and sink fast.

I believe in the past there was also that problem with the downwash skipping through the ground, but I believe that one was fixed, and it was only after that that Austin implemented the relative wind reduction in the last 30+ ft ( 10 m ).

Jose is right.

X-Plane implemented a reduction in wind speed close to the ground, based on the official testing data from wind turbines, iirc. Just like any airflow in a laminar effect situation, wind will also slow down the closer you get to the ground. Thats why you can see birds fly really low against a headwind, for example.

The wind reported at airfields is measured in a certain height at the weather reporting station, something like 10 meters. A Cessna 172 will be at ca. 2m at touchdown, though - so considerably lower than the height at which the wind was measured and reported.

This reduction in wind speed can be quite drastic. Not quite from 30 to 6, but from 30 to 15 would be possible...and I personally feel that some effects (like turbulent layer speed retention) have not been portrayed well.

In other words - if you come in with a strong headwind in a "small" plane, get ready for a negative windshear as you approach the ground. Just like on any windy day, carry some extra speed into the approach.

If you come in with a tailwind, the opposite effect will "add" speed to your landing flare, and you need to plan on flying the airplane into the ground some more.

Opposed to what most people think and observe, excessive floating both in the real world and in X-Plane is not an effect of the "ground effect". The actual increase in lift is minuscle, the bulk of the "ground effect" is a reduction in induced drag. Google it if you don´t believe me.

Excessive floating is caused by excessive indicated airspeed combined with a wrong flaring technique.

I think you might have been trying to disagree and ending up arguing with yourself?

I think what you probably meant to say was something along the lines of:

"excessive floating both in the real world and in X-Plane is not due to increased lift. The actual increase in lift is minuscle, the bulk of the "ground effect" is a reduction in induced drag."
