Flying R44 and R66, the sim feels very good vs IRL but ground effect is too strong. The Ground effect is typically felt at a distance equal to the diameter of your rotor, below your airframe. All helicopters have the same effect in sim, not proportional to their rotor diameter IRL. Good Cyclic and anti-torque feel in general flight. Even in 6DOF motion rig, it feels good in ground and air models. 2024 helicopters in general are better than 2020. Please fix the ground effect.

Thank you for the bug report.
We have created an internal ticket to see if our team already has this logged, and if not they will attempt to reproduce the issue and create a new bug report. This item is now marked as feedback-logged. If there is an existing bug report or one is created, we will move this thread to bug-logged

Nope, not a good thing. This is a bad thing. This was a bug in 2020, has been fixed in 2020, but the fix did not make its way to 2024.
Clear indication of dysfunctional QA.
You are reading my post out of context. My reference to Asobo improving the flight model for helicopters was in relation to an earlier observation I made about translating tendency.
I posted separately regarding the odd behaviour when approaching raise helipadsâŚ
âOn this point I believe the sim is known to be a bit bugged in this respect. Not tried it myself yet, but it may be the sim is reacting to abruptly to the change in ground effect as the helicopter suddenly gains ground effect as it passed over the raise platform.â
Thanks for your reply. But, I have difficulties to follow your point. I am not really sure to have replied to your post, neither to have it read out of context nor having it read at all before my post⌠Thats what is confusing me a little bit.
Did you intend to reply to my hereby cited post or something else?
Maybe you feel like clarifying this a little bit to me, I would like to go through your oppinion.
As far as I know, this is simulated absolutely correctly and is a peculiarity of this helicopter. The H125 tilts about 3-5° to the right when hovering. In forward flight, this tilt balances out aerodynamically.
You can see this clearly in the following video:
first the left skid lifts and only then the right one. In hovering flight, this helicopter is always tilted slightly to the right.

Using the template below will greatly help the team reproduce the issue and ease the process of fixing it. Before posting, search for an existing report. If you are not sure itâs a bug, please first report in User Support Hub.
3 tags are required - add them in the tag section next to the title above:
- One for iteration (msfs-2020 or msfs-2024)
- One for platform (ms-store, steam, xbox, or xcloud)
- One for aircraft (start typing in your aircraft name in the tag section and pick correct option)
Feel free to delete this quote section after adding your appropriate tags.
ISSUE DESCRIPTION
Description of the issue:
MSFS2024 - When flying any helicopter above a helipad, where the pad is located on a tall building, there is a sudden upward pushing of the helicopter up away from the pad. This is sudden and abrupt, with no warning. This only happens when the helicopter is directly above the pad. This does not occur with ground-based helipads.
If applicable, which aircraft is experiencing this issue:
Iâve experienced the above issue with CowanSim 500E, Cowan Simulation H125
[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue? I have not added may content to the MSFS2024 Community Folder.
FREQUENCY OF ISSUE
How often does this occur for you (Example: Just once, every time on sim load, intermittently)? What I am reporting happens every time, in any weather condition, day or night.
REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
- I tried landing a helicopter on a ground-based helipad, with no issues.
- I tried landing a helicopter on a pad located on a 1 story build, with no issues.
- I tried loading a helicopter on various height tall building, where the issue occurred with each attempt, clear weather.
YOUR SETTINGS
If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.
What peripherals are you using, if relevant:
[PC Only] Are you using Developer Mode or have you made any changes to it? Developer mode is turned off in MSFS2024 by default (I think).
[PC, MSFS 2020 Only] Are you using DX11 or DX12?
[PC Only] What GPU (Graphics Card) do you use? Nvidia RTX 3080
[PC Only] What other relevant PC specs can you share? i9 12900K, Water Cooled, 64GB DDR5
MEDIA
Please add a screenshot or video of the issue occurring.

Do you have the same issue if you follow the OPâs steps to reproduce it?
⢠Yes.
Provide extra information to complete the original description of the issue:
⢠This is the exact same issue that was reported for 2020 and fixed in SU15, for more details, see [Helicopter] Abrupt induced yaw when flying over edge of elevated helipad and Helicopter ground effect transition is abrupt and requires large inputs to recover - Aircraft - MSFS DevSupport.
This bug was frustrating the first time in 2020, but that the fix did not make its way into 2024 is even more frustrating, we are back to square one after almost two years. This was reported in January 2023 first on DevSupport, it took a year for Asobo to fix it.
This bug is pretty much kills all the fun of helicopter flying. Wondering if anyone ever tried to land on that spray truck shown on the trailersâŚ

I agree with this topic message too. Also for better understanding the effect the visualisation of CFD should be tweaked or even changed (the new one is way worse than in 2020 visually making it more difficult to see how the FM works not easier). I think we should simply have the option to have instead of those blinding lines some water spray effect or something thinner and more like the visualisation of the wake turbulence shown on âpreview videosâ of msfs2024 that is nowhere to be found now.

This is called âtranslating tendencyâ or âtail rotor driftâ and is normal for single-rotor helicopters (i.e. helicopters with a tail rotor).
A tail rotor inherently produces sideways thrust as it counteracts the torque of the main rotor. Tail rotor thrust will make the helicopter drift sideways in a hover â unless you tilt the main rotor to cancel out the drift. On some helicopters this tilt is built in, and on other helicopters you must hover with one skid low.
Hereâs a good video about translating tendency:

Do you have the same issue if you follow the OPâs steps to reproduce it?
Yes. Going from ground to a raised object is an immediate, exaggerated lift effect. There is no transition what so ever.

Same here, which means we have anoter soft lock in the carrer mode. helicotper agricutural missions are totally unflyable since is impossible to land in the refill truck with this issues⌠We are beta (or alpha) testing the entire sim at the moment

Nope, itâs much worse than that. This bug was found in MSFS2020, almost two years ago, and fixed in MSFS2020 SU15, likely after they forked 2024, and it speaks volumes about their QA that they werenât able to merge/cherry pick the fix for a known bug to 2024.

What QA? Have you seen the general state of everything in the game? Pretty much everything in terms of power in helicopter flight model is grossly exaggerated, VRS - just add cyclic, it has enough power to pull you out, fresh air flow - the moment you gain 2kts IAS you have a burst of lift that is enough to go up hundreds of ft/m.
Examples today during our group flight. First landing with the wind, the CFD visualization completely disapears as one approaches the platform. (Timestamp 1:21:06)

Second landing is into the wind, and the CFD behaves much better and only partially get affected by the platform (Timestamp 1:28:17)

To add to this, I found, on the Cabri G2, that by assigning the lateral trim increase/decrease to a hat switch on my joystick, I was mostly able to trim out that translation tendency. I suggest others try it as well.
Unfortunately, to my knowledge, the H125âs trims donât seem to be a thing or are just not working, so it may not help the 125 specifically.
