[REPORTED] Error in Ground Effect?

How has this not been fixed yet??? And no response from ED???

FM programmer is busy doing something else. Wags said that the FM will get a revision after he finish his current tasks.

Flying third mission of the 'Serpents Head' Campaign you got to 'evade' SAMs flying as low as possible from Kutaisi to Gori.

Low and fast.

This is when I for the first time had the 'experience' of this Bug. 'Pull up, pull up' I was already pulling but because of rising terrain for a few seconds at +400Kts I got below 50ft agl - and as of a sudden - baaam like I got sucked into the ground. First of I thought of some high speed stall but then again - I wasn't supersonic nor at high AoA - just low and fast...

Will try to regenerate to get some .trks

Go seaskimming. Establish 100ft, trim VS for like -100ft/m, no more, and watch.

Below 50ft you will need to retrim, below 20ft you almost can't stop the drop with full stick aft.

With the Mirage I can switch outside to F3 view down at 10ft...

I’ve been following this thread since it’s creation, and also have experienced this anomaly at low level over the ground and carrier deck. I also agree with the poster that makes the case against ground effect, and I’ll go a step further and say it’s not the burble when experiencing it during carrier landings. I’ve been doing nothing but traps lately and each and every time when a few feet over the deck I’ve watched the AOA go from on speed to fast with no pitch input from me. I never had noticed this till recently. I really hope this is fixed soon, I wouldn’t be surprised if this has contributed to a quite a few bolters.

Regardless... we never got a [REPORTED], [CAN'T REPRODUCE], [FIXED INTERNALLY], [ALREADY KNOWN] or even just a [NOT A BUG]. So probably not even at ED anyone knows if this is being worked on or not. All we have is hope they are aware of. Too bad there are tons of issues that at least seem to be completely ignored by both the devs and the moderators. If they're not ignored, it's fine.

Hi,

Same here, on my track you can noticed on the HUD, the vertical speed is positive before / while the plane is strongly attracted by the ground.

Best Regards

PS: would it be possible to simply reverse? something like a typo as a "+" has become a "-"?

For the F15 is the ground effect simulated?

The plane descends slowly until the crash (check tracks).

Should not it be pushed back by the ground?

By cons it is not strongly attracted to the ground as the F18

Is any work being done on this? It's really ruining my carrier passes. I'll have a good, maybe slightly high, ball all the way down to the run down, then as soon as I cross the run down my jet gets sucked down by a tractor beam for a 1 or 2 wire when I should have had a 3 or 4 wire.

I noticed this just yesterday on the Blue Flag server.

I was flying very low over the sea, at around 40 ft, the airplane started to get sucked down, I had to pull very hard to keep it from hitting the water. The same thing happened every time I got below ~40 ft. Very strange.

This is exactly what happened to me last night on Blueflag except I wasn't so lucky.

Having come across this thread I must say it's very disappointing to see ED turn a blind eye to this issue. Almost 7 months without comment is appalling.

Still nothing on this?

I also noticed the F-5 suffers from this as well. Is this a common thing with Belsimek aircraft?

I've noticed this too and found the best way to see it happen is to fly over the deck of the Stennis going 350 knots. I need to pull like a mad man to stop it from going into the water.

Same here.

Well remembered Strikeeagle345, I also noticed that on F-5 :thumbup:

The flight model team must be either misinformed how ground effect works or they are putting the values in wrong / opposite of what they should be.

bump, happened to me last night when flying low over the water

I reported the same finding about being sucked down into the ocean in the bug forum in july 2018. ( a guess, cant remember the date )

I'm wondering if this was something that was programmed in to simulate the burble (i.e. disturbed airflow from the carrier island), but they didn't know how to program it specific to the carrier and it just happens any time you get close to the ground/deck. If that's the case, I think we'd all agree it'd be best to remove it entirely.

it happens on the F-5 too (same developers) so i think it was just done incorrectly.

Try to fly inverted over a hilltop at 20ft. Most interesting result.

let me guess, it pushes you away rather than sucking you into the ground?

Correct!

This is interesting because the other day I made these two gifs while I was testing this odd nose dive on touchdown. Probably exactly what is happening here, there carrier ends up pulling the nose down due to the inverse ground effect.

The first is MIL power just before touchdown and the second is MIL on the ramp.

I just realized the throttle movement has nothing to do with the dip on touchdown. I tried it not moving the throttle at all as well as moving it to idle and the same thing in the first gif occurs.

For completeness, here is the track.

awesome, looks like this thread is set to reported! finally!!!
