Did someone else notice that oscillation on climb in pitch/speed mode? Gives me MSFS default autopilot flashbacks. It's by far not that pronounced, but still annoying. Unless it's deliberate as the real aircraft does it as well... 😄

Funny thing is, he said "its a bit bumpy here" uhhh doesn't look like turbulence to me lol.  Looks like that slow msfs oscillation lol but hey i could be wrong

I don't get it with some of you people! the plane is'nt even out yet and your whinning like a bunch of children. Aerosoft are leading the way in this new sim, yet all you can do is critcise at every turn.... Quite simply if you don't like it, go fly your " Study level" stuff in your 10 yr old sims... And i for one fully appreciate the tutorials Aerosoft, and The Dude have supplied for our learning..

Because their implementation is 100% in Javascript gauge which allows outside world communication, whereby WASM (C++), as this moment doesn't allow outside world communication. Anyway, as Matjias, this will change as Asobo sooner or later will enable outside communication from WASM.

Ah got it. Thanks for the explanation

There may need to be some tweaking of the autopilot, but I can say that the real CRJ will typically not hold a constant pitch. The standard climb mode is based on controlling airspeed with pitch. In the CRJ, this is called CLB mode - other aircraft  refer to it as FLC mode. Since engine power is fixed in climb (controlled by the FADEC), the aircraft will prioritize airspeed, and the resulting vertical speed that results “is what it is”. The pitch required to hold the selected airspeed will change as the outside temperature, pressure and wind varies. If the aircraft climbs into a layer of unusually warm air, the nose will pitch down, and vertical speed will drop. At worst, the aircraft will stop climbing - it will never descend in CLB mode to maintain speed. On the other hand, if air temperature is unusually cold, the aircraft might be able to maintain a very brisk climb rate indeed.

I am a mechanic for a company that operates three CRJ-200s. There is a corresponding speed-on-pitch mode that can be used in descent, but it is rarely used, because it can lead to the very kind of pitch oscillations you see in the video. Descents are almost always done at a constant vertical speed. Vertical speed mode is almost never used for climb however, because it offers no protection against stalling - especially at higher altitudes. Pilots may switch to VS mode during the level-off portion of a climb, but not before.

Nice one Jim! So basically, you could expect slight oscillations, but not in a rhythmic manner.

Yes. I don’t know to what extent the sim’s atmospheric model may contribute to the problem. Although the CRJ will have mostly custom systems, it may still be affected by things in the core sim aerodynamics - just as the recent problem with the incorrect flap aerodynamics in World Update 3 affected every MSFS aircraft - both default and add-on. We already know that the initial release of the CRJ will not have a working weather radar because the SDK functionality to implement that does not yet exist. The version of the CRJ used in the video is a pre-release beta, so I assume it is still being “tuned”, and will probably be further modified for any changes in the core that come with Sim Update 3 next week.

Yeah, I am familiar with FLC mode. In the video it appeared that it's a constant oscillation though. Much like the reknown dolphin swim - just not as pronounced.

dude-calm down 😄

Aerosoft are releasing these videos, it's entirely appropriate to comment on a pretty obvious flight model/autopilot issue that everyone can see, that doesn't equate to "criticising at every turn"

no-one's judging the product, it's not out yet 😄

and no need for anyone critical to "go fly study level stuff in 10 year old sims"

dare I say it, there's only one person reacting like a child here 👍

exactly, that wasn't pitch adjustments associated with FLC mode, or at least if it is, it needs smoothing out a bit

Strange, 7 others seem to agree with me.

Wasn't there a rather infamous crash of a CRJ2 where the pilots in a ferry flight used VS to climb to FL410 (service ceiling) and in doing so got way behind the aircraft on energy, then had a double engine flameout and engine stall, and couldn't get them restarted?

LOL. If you are referring to the videos from „The Dude“: He is a real world CRJ pilot...

He is indeed a real CRJ pilot and he's video was excellent. But if a promoter doesn't mention that it took 15 CTD's to make it and never mentions what is broken and inop in the product, then it's an issue that only "real world" reviews will take up. That YT promoter will have lost all integrity and respect no matter who they are.

Yes, correct

That's the one I was thinking of. Yikes, the CVR transcript is wild.
