Aside from the bad physics still present in MSFS2020/2024, there are also problems with adjusting peripheral sensitivities, which should have a linear response rather than curves. After reviewing many YouTube videos (in particular this guy), it's clear that a very high percentage of people continue to overcontrol their flight controls. Yes, at those wx conditions, you will encounter up/down drafts, but not what ASOBO thinks. It's really difficult to understand where they get this, and whether they would ever correct these issues. See 2:13:00 of the same video, as he approaches KSLC. Even with AP on, the plane is being pushed around like it's a Cessna. You're completely right that Asobo's turbulence is exaggerated, but still, I've flown in the same conditions in other airliners and they do not get tossed around like that. In fact, I flew the Fenix A320 into KLAS yesterday at 40C, and while I definitely felt the thermals on approach and had to make constant small corrections to maintain the flight path, it still behaved like an airliner and not a Cessna. Even the PMDG 737 in MSFS 2020 (which has its own flight model issues) did not get tossed around quite like the iFly did. The reason why this is so jarring is because the iFly flight model feels so good otherwise. Edited August 11, 2025Aug 11 by RNAVV19R

Having in view that @Stearmandriver it is current and qualified in the airplane, his evaluation is very important and should be taken into consideration. I flew the 734 many years ago, and it has nothing to do with this one. About other "airliners," we might want to consider that some are more stable than others, even within the same category or type. I will give a few examples of airplanes that I have flown and remember very accurately. A340-200 and 300 are less stable than A340-600 or A380. B747 SP is less stable than the 100, B747-200-300-400, while B748 or B777 is very stable. Of course, all are affected by turbulence to a certain degree, and some fly like "on rails" regardless of size. 747 Captain for the last 39 years, and still learning.

August 12, 2025Aug 12 Author I saw a recent stream from another individual landing in KLAS at 40C and the iFly did not exhibit this behavior, so it looks like there might be another issue that is causing this for some users. Maybe the presence of some other addon is causing the issue, though I am not using FSRealistic or any weather addon. The iFly is only experimental in MSFS 2024 anyways. Hopefully this won't be a problem once the fully native MSFS 2024 version drops. Edited August 12, 2025Aug 12 by RNAVV19R
November 1, 2025Nov 1 Hmm , i am having a weird issue only with this one. The HUD is deployed in cold and dark state and as soon as i connect the GPU the aircraft 1-2 seconds after starts pushing back. No brakes works Michael Moe Michael Moe

Very stable, you just need to use decent amounts of trim to smooth out climbs and descents. you cannot be flying the same Ifly plane. The approaches are unstable and the ILS tracking is off a bit.

November 2, 2025Nov 2 I am interested in getting the ifly 737. From what I have seen or read, I am not convinced yet.

I just tried a flight from PHX to LAS, and the plane handled flawlessly. It followed the localizer and glide scope and a perfect flair, spoiler deployment. Also tried another flight from ENSB to LIMC also went perfect.

It's got a couple of minor glitches specific to 2024 but nothing that has any real impact on the overall experience. Once these guys release their long-awaited update, with the new EFB and kill those remaining FS2024 bugs, this thing will be right up with Fenix.

However I noticed that the lnav mode became bit more unstable after those changes. I mean lnav starts the turn,overshoot and turn back to a track to the next point. Did you also notice same behavior? Or maybe you did more fine tuning later?
