Helicopter CFD Must Never STOP!

CFD on helicopters stops permanently and the helicopter is ungovernable for a few moments, this happens on any elevated surface approaching at low speeds.
I hoped that after the gigantic update released a few days ago, this very important BUG on the flight dynamics of helicopters had been resolved, unfortunately not! I hope it will be considered before any other bugs regarding helicopters, otherwise helicopters are just toys. This problem is not present on airplanes, because airplanes do not fly close to the ground but helicopters do. I hope it gets resolved.

Your title is a little confusing.
“CFD suddenly refreshes over elevated landing platforms”

It looks like this happens when the model center passes over the platform.
Turn on the wheels debug menu. (if you can)

Linking some of the other threads too:

And the recent Q&A where Seb mentions he will look into it: https://www.youtube.com/watch?v=mbx-5qulY2k&t=2443s

Hi Dave and thanks for adding your links, I didn’t want to do confusion adding also my post, I just would like this big problem not to be underestimated, for this reason I made a video with the moments in which the CFD stops. How you say too, this problem seems to be linked to high differences between radio altimetric heights, but, you think that the reaction of complete data shutdown (as shown in the video) represents a switch between the 1-0 value of the use_modern_surfaces? I also did other tests from the SDK with the SURFACE TYPE variable and I see that this problem also happens when the type of terrain changes, maybe CFD is not proportional and the Asobo developers need to use a “trick” to interrupt him in some difficult data calculation phases during flights? I think it is really a very important problem to solve, otherwise your fantastic helicopters are underestimated. I have purchased both of your helicopters and I really appreciate your work and for this reason I hope they solved soon.
