F100 - ATS and Landing behaviour
-
I experience the same. Using MSFS 2024. The aircraft struggles to maintain speed, the autopilot seems to be too slow in response, resulting in unrealistic large pitch oscillations and large thrust corrections. It would be nice if JF could tweak this behaviour and make the autopilot more responsive.
-
Wanted to step in here too to report a surprisingly large variation of speeds during an approach in calm weather conditions.
Approach speed varies in a range of like 20 to 30kt when handled by ATS and I've found it to be super super difficult to manage energy on approach an landing.
I've done three flights so far and every APP was messed up to an extent that I should have gone around.
Been flying various sims and different aircraft (yep, Boeing and Airbus) for 20 years now and always been able to quickly get used to new environment. Sure, a part of my bad approaches are due to differences between Fokker and A/B which I just have to get used to but it feels like some parameters of the addon could use a little fine tuning too. -
I'm not sure it's all the ATS' and A/P's fault. I'm not sure how it's calculated in the real aircraft, but I've seen that the speed trend indication is very very responsive, much more so than in any other aircraft I've flown. I usually never use ATS on final (in any plane), but I've basically having to force myself to disregard the speed trend indication or I would end up doing some very excessive and unnecessary throttle changes myself (something that did happen for the first half of my first approach, before I noticed).
Also, even though it's slightly off topic, since someone mentioned FLCH, if you fly manually and have the F/D vertical mode in FLCH you'll see that the flight director has a similar problem, the commands are very large and vary very quickly. Maybe this can throw off the A/P and ATS?
Next flight I do I'll try to get some footage of both of these things.

Is there any fix for the "nose down at ap disconnect" and massive trim up needed on the horizon?

@storemaster For a moment I thoguht Flaps 25 instead of 40 was a way around, but talking to friend that looked like just a coincidence.

Had a vAPP of 121kn today and I didn't manage to perform a stable approach.
Aircraft accelerated to 160kn and even higher as you can see on this screenshot (wasn't able to record a video quickly enough):
@OELVA Second this. I had erratic speed changes up to 160kts, all the way from 121kts which was selected.

I would like to chip in here with my modest observation - this might be an issue occurring only on MSFS 2024, imho.
I flew F100 in MSFS 2024, LOWW-EPKK, the turbulence settings set to low and nearly no wind, the plane climbed in profile mode, was unable to follow FMS selected IAS. Oscillations were always +/- 20 kts. The throttle was stable in climb thrust, but the plane was unable to follow the FD properly and was overshooting the selected speed until a cruise altitude was reached.
I flew F100 in MSFS 2020, the same route, the same conditions, the plane kept the speed in profile climb without any issues (tiny variations due to the wind, absolutely normal).
I also flew F70, only in MSFS2020 on LOWW-LZKZ-LOWW, different cruise altitudes and speeds, always flown accurately. Did not fly F70 in MSFS2024.
The ATS is sometimes slightly sluggish, but as Mark says, that is to be expected, and I did not find the ATS behaviour in MSFS 2020 particularly problematic (would say that 737s by a famous developer have a similarly sluggish auto throttle).
Could it be the difference between simulators?
@MichailusB
Can anyone else who uses MSFS 2020 confirm this? I use MSFS 2024 and the plane can't maintain speed on climb ( even on descent in LVL change mode it oscillates a lot ). If this is a case of only in MSFS 2024 issue then it needs to be investigated. -
Hi all!
I had huge problems flying the f100/f70 in real weather. Approach speeds fluctuating wildly and incontrollable aircraft. But, I found a solution in the internet which seems to work on my pc. It’s a windows problem (!). The OS clock synchronization, didn’t work well (but check also DNS and IPv6). It caused MSFS2024 to mess up winds, particularly during last 500 feet AGL of the approach.
