• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS2020 New [FLAPS] Section parameters

Have a - careful - look into the FBW A32NX MOD "flight_dynamics.cfg",....

As Roy mentioned, the point is that the main reason for the stall speed reduction due to slats is the higher useable AoA, which requires a change in the lift curve. I don't think that FBW achieved that.
Changing values in the cfg file will only change flaps lift (from an aerodynamic POV), hence no slats simulation in MSFS.

A lot of alpha testers, me included, asked for 'real' slats right at the beginning of alpha testing. Can't imagine that Asobo disregards this essential flightsim feature.
 
Well :-( Let's hope they open their heart / mind to the claims of the devs

At least they appear to be commited to try to change what is wrong, fine tune, maybe even add additional stuff... I hope for the best...
Otherwise, it's always the same - back to the dark side, and DCS :-)
 
The bit that worries me is the mess they are making of jet performance. That was one part of the old sim that worked really well and they now have PIDs where you don't need them, response is awful and as for accuracy, it has disappeared.
What is the point of getting drag perfect if the thrust is screwed up?
Roy
 
As I understand it, (but I haven't been working with it, so I'm not sure), they've gone back to allowing most or all of the old tables in the engines.cfg file to be used again. You just have to set a variable "use_table_name" = 1.
 
@Roy Holmes
Yes, that is indeed a bit worrying, but since sales seem to be at least 'sufficient' for MS, I do assume that Asobo will keep working on improving the new FDM over the coming month/years.

I'm almost sure we'll be able to taste one of your creations one day ! maybe sooner than later ;)
Let me see.... 310 looks like a charming option ;-)
 
Hi Guys,

Wondering since the update from yesterday, they implemented some changes to the flaps setting and behaviour inSim.
Planes seems get generate a lot more lift when the flaps are deployed (ballonning)

Any idea's on this?

The main requirement from flaps is to allow the airplane to fly slower usually in connection with take off and landing. Since the weight is relatively constant that means they need to generate the same lift but at lower speed. Lift is proportional to indicated speed squared and directly with lift coefficient Cl. So you need to increase CL to decrease landing speed. The flaps do this.
As you lower the flaps lift will increase by more than you need for the speed so the airplane will tend to balloon. How much it does depends on pitch stability.
MSFS, as discussed elsewhere in this forum, has exaggerated unrealistic reactions to control inputs and that is most likely why it balloons. There are coefficients that can minimise that.

Yes, they messed up. Supposedly they are going to address it soon.
