bkthunder Posted June 8, 2019 Share Posted June 8, 2019 Reverse ground effect getting stronger? I was flying low over the runway at about 80 feet and literally got sucked down and crashed. I'm aware of the reversed ground effect bug, but did it just become stronger with the last patch?

I forgot about that one... so is the terribly broken weaponry drag on hornet (dropping bombs makes you faster than an airplane spawned as clean). likely the flight model guy was transfered to f-16.

Svend_Dellepude Posted June 8, 2019 Share Posted June 8, 2019 The FM did not get the revision yet. The guy working on FM is doing some system on the F-18, and when that is finished, he is gonna revisit the FM. All stated by Wags himself. I think it's stated in the mini updates a while back.

Only Lex and GB know for sure on this forum what the plane should feel like. The rest of us are guessing. Buzz Link to comment Share on other sites More sharing options...
oldcrusty Posted June 8, 2019 Share Posted June 8, 2019 ...The rest of us are guessing. No guessing about inverse ground effect and few other things:) You'd be surprised how much resources are there... among the rest. btw, I was kinda hoping that some RL Hornet guys are involved with testing and "occasional" feedback to the devs through whatever channels of communication.

Chuck_Henry Posted June 8, 2019 Share Posted June 8, 2019 Only Lex and GB know for sure on this forum what the plane should feel like. The rest of us are guessing. While true, there is no aircraft in the world that experiences reverse ground effect. It would literally defy the laws of Newtonian physics and blade element theory.

Svend_Dellepude Posted June 9, 2019 Share Posted June 9, 2019 ED has on several occasions welcomed documented feedback, so if you have anything documented, just send it to them. They can, however, not build a sim based on peoples feelings expectations and varying sense of logic. The ground effect have AFAIK been acknowledged some time ago: https://forums.eagle.ru/showthread.php?t=213372&highlight=ground+effect ED have SME's working alongside the programmers and the F-18 is still in EA.

No you get it on airfields as well .. it's a flight model "quirk" in the Hornet, it has reverse ground effect. Link to comment Share on other sites More sharing options...

DrGarantia Posted June 10, 2019 Share Posted June 10, 2019 I tried flying low to evade some SAMs this weekend twice, both times at around 30-40ft the plane is sucked to the ground, can't say if it is stronger than before, at least the effect is still there.

Eldur Posted June 10, 2019 Share Posted June 10, 2019 The last time I had this I G-LOCed due to heavy neg G due to the nose down pull, just before I crashed into the ground rather steeply. All that shortly after flying level across the ground at low altitude When I noticed it beginning, I immediately pulled back completely and pressed my paddle switch, to no avail (I had this saving me once already)... noone can tell me that this might even be close to being realistic at all.

HoBo777 Posted June 10, 2019 Share Posted June 10, 2019 (edited) There have been no such changes. It does seem stronger, are you sure they haven't been trying to fix it? That would honestly make me happier than no changes. The reverse ground effect has been known about for nearly a year.

oldcrusty Posted June 11, 2019 Share Posted June 11, 2019 Someone decompile the game and flip the sign on that line. For the Hornet?... might as well take out the whole line. Not much of a noticeable ground effect in a Hornet... from what I hear. "Local" Hornet pilots' comments welcome:) I don't think it's just a line though, most likely some unintended side effect from some other part of code. Or perhaps it is one line, lol.

bbrz Posted June 11, 2019 Share Posted June 11, 2019 (edited) Just did a few more tests and IMO it's definitely not an 'reversed' ground effect, it's a pitch down moment that is introduced at very low altitude, below 30-50ft. Noticed that exactly the same phenomenon occurs (at least) with the MiG-29 as well. At low speed and high AoA I could understand this effect, since the downwash of the very low positioned stabilator enters the ground effect before the wing does. This reduces the stabilator downwash, increases lift and produces a noticable pitch down effect. This effect is very noticable when e.g. rotating on take off IRL in big jets. As soon as the horizontal stabilizer descends into the ground effect you need to increase the pull on the yoke to keep the present rotation rate. Starting to climb, the stabilizer leaves the ground effect and you need to relax the back pressure. @Gripes, with this large flaps and flap angle on the F/A-18, there is for sure a 'theoretical' ground effect. But taking into account the high wing loading and that Hornet pilots usually don't shoot for greasers and the rather high ROD it's not noticable I'd say. But this pitch down even occurs at high speed, e.g. at 400kts where the relative position of the stabilator is higher and it produces much less lift.

bbrz Posted June 11, 2019 Share Posted June 11, 2019 (edited) Just re-tested. If ground effect for e.g. the stabilizer isn't calculated seperately, then it's indeee a 'reverse' ground effect and the pitch down moment is simply the result from the loss of lift. With the F/A-18 at 300kts I need an approximately 0.5° higher AoA in ground effect.
