• 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.

Is there a standard notation for aircraft attitude?

This is a general enquiry rather than pertaining specifically to FSX:

Are there standard ways of describing an object's attitude is heading, pitch bank? i.e. FSX uses 0 to +/-PI to describe pitch, where a negative value denotes pitching upwards.

Does this conform to any known mathematical notational standard, or is it simply MS's choice?

I believe in the past I've seen references to Euler Rules in relation to attitude descriptions but can seem to track down anything specific.

Si,

The only thing I see in the SDK is that FS used DirectX and that uses the left hand - coordinate system.

X is horizontal positive right (wing) (Thumb)
Y is vertical positive up (fin) (index finger)
Z is positive into screen (nose) (middle finger)

X and Y make a L

Pertaining to 'angle of attitude' when in cruise flight or max flight speeds, I was not able to find any such setting. I wish there was, but I found none. I had requested help from alot of people that are well versed on tuning air files.

What I did which you can do, is to either adjust your lift characteristics and elevator angle (not elevator itself, but the horizontal stabilizer angle), or if everything is as you like it, then you will need to 'move' (rotate on X axis) your entire plane slightly to allow the angle to be more exact to your likings. You can do this by selecting everything in a scene 'except' the 'exterior' or 'interior' nodes (if working with those) and rotate everything slightly. Make sure you do this as a seperate build and not to ruin a valuable file. This is sort of a touchy procedure, rotating all the parts...

The adjustment for angle of the Horizontal Stabilizer in the 'aircraft.cfg' file is;

htail_incidence=0.000000

Adjusting that will effect angle of flight, as well as effect your take-off abilities. For instance, if you add enough to keep the nose down in flight, it will require up trim on take-off. If you apply some angle to keep the nose up in flight, your plane will take off more easily (perhaps too soon) on the take-off run, (as though it has too much up trim).

Good luck on that.
