I reported this as a feedback loop issue a couple of weeks back. Not much we can do until they have a permanent fix except work around it, which you can.
I’m not interested in immersion breaking workarounds. I’m interested in planes that at least work at a baseline level. They said that this game is a flight simulation, first and foremost. And that is the standard they will be held to.
They made their bed. They will lie in it.
But complaining doesn’t solve the problem. Feedback control algorithms are complex and they will need tweaks for every aircraft to work flawlessly whether your in calm weather, headwind, tailwind, your COG, weight, and so on. It’s a simulator, so they can simulate it wrong. Use VS and wait is the best option.
Please use VS mode only. I have never used flc on any plane in this sim, its still wip…works way better in this mode. Use the guide in the longitude threads to fly it better.
Thank you mr mooreysj! Well said. The sim is still new, and it wil take a while for things to fix. I have been flying the longitude and others using the workarounds posted here and all my flights were smooth and trouble free even to ils finals..I make do with what I have now and I don’t fret. Really enjoying this sim !!
I understand your disappointment…please realise it’s new software like any program and it will take time to fix, just like Windows. Buggy when it came out, but all working good now.
Tuning these controls is not that hard. Three numbers, P, I, and D. There are even algorithms that can auto tune based on the data plots from a failed test. You do some math on the recorded oscillations and calculate a new target. Even if they had to hand tune one aircraft a day, in a month 1 person could fix all of the aircraft.
The problem is that many of the aircraft in the sim have a dynamic pitch instability. A real aircraft will trim out to a content pitch/airspeed/rate of altitude change for a given power setting. Even if you try to fly without AP, the aircraft in the sim display long period phugoid oscillations that do not damp out when you try to trim them for straight and level flight.
If the period of the AP control loop is similar to the period of this flight model pitch instability, bad things happen.
This is basic aircraft stability and control stuff that we covered in my junior year of aeronautical engineering. If I were working on this sim I would be embarrassed to ship it in this state.
Given the dynamic instability of the aircraft, I suspect if they had increased the speed of the AP responses instead of decreasing it, that might have actually helped…
(Cessna Longitude) I only use FLC when descending and it works ok. Going up i use VS.
Yes, there will be bugs in new software. But at the same time. There is also a minimum standard for a product that you are advertising as a release-worthy game, and not “early access”. And MSFS does not meet that bar by a pretty significant margin.
I can’t disagree with you on the shortcomings. However, as a lifelong software engineer I learn to work around or not use the incomplete features. I’ve been fortunate to not have more than a couple of CTDs and I only fly the TBM which has worked pretty well.
I disabled multi-player and auto-generated traffic because they don’t interest me, so I’m eliminating some of the problem areas. When I encounter issues I file bugs. Overall I think it looks great, and I think the pressure on Asobo will make them deliver a more polished product moving forward.
The TBM is one of the first planes they started working on, and is generally the most stable and mature of them all. The same is not true for the others. And the crashes to desktop are much more frequent for me. Hard to use workarounds when the game randomly nukes itself. In a 30 minute lunch break, I got about 4 minutes of actual flying in because of crashes.
I find it very odd that there’s such a wide variety of experiences with the game. I’m not really a gamer, but I’ve always loved flight simulators. The only other game on my PC is Cities Skylines. I feel that the more hardcore gamers who overclock and tweak their environments seem to have a worse time of it, with this constant desire to squeeze every ounce of performance from their systems.
I’ve been watching this post for the past couple of days and there’s a comment from @AlbertR, who says that says he was recommended to install or reinstall the English language pack. Odd requests like this make me wonder if there are a few dependencies that should have been covered in the installer that were missed by Asobo.
100% stock system here. No overclocking.
Also a software engineer specializing in realtime graphics. There’s just such a big combination of hardware and software configurations that one system might be fine. but another system has issues.
Ironic .. (assuming you are right),
For the C175 they appear to have doubled the AP response rate, in an attempt to “tame” the Aircraft Dynamic Pitch Instability.
Yeah that’s for sure. Have you noticed any consistency in the event logs for which module is causing your CTDs?
I have the “dolphin dance” in 1.9.5.0 without engine with sailplane models not from Asobo. That is, I assume the problem is not in an individual airplane model, but in some common code for all airplanes. Let’s see how many months or years Asobo needs to fix the bug.
As I pointed out in the original post, I get severe oscillations in the Longitude regardless of whether I use VS mode, FLC mode or even just ALT hold mode. Using VS mode instead of FLC does appear to help in the CJ4 and 747-8 though.
I haven’t overclocked any of my hardware or done any other unusual tweaks.
Not working for me.
What confuses me, is that the Longitude’s AP was working just fine when the sim was released. Something was done in the 1.9.3.0 patch that screwed it all up. I don’t get why it is so hard for them to figure it out…
