SAU Recovery Mode with FFB Joystick

[Flagrum]

When enabling the recovery mode while maneuvering (i.e. aircraft banked and pitched), the AFCS steers the aircraft back to level flight. It's operation can be observed by watching the stick moving accordingly in the cockpit in it's X and Y axis.

 

For the pitch axis deflection, initiated by the AFCS, the FFB joystick follows the movements of it's virtual counterpart, but for the roll axis, it does not!

 

Joystick used: G940

Tested under 1.2.16 and earlier (i.e. not new, but somehow it never occured to me beforethat this is not right ;o)

Now that you mentioned it :doh::doh::doh:

You´re absolutely right. Have the G940 too. Same behaviour.

Additionally when I cancel SAU mode in level flight, depending on the speed the aircraft pitches up, stays level or pitches down. Do you have this aswell? I guess it´s from the double trim bug.

I haven't tried that, yet, but what would that bug (I still fail to really comprehend what the real issue there is supposed to be...) do to cause that behaviour? My first thought was rather, why should it not pitch up/down when disabling SAU? You would expect the controls to remain in the last position when SAU was still enabled (i.e. when the a/c was stable)? If SAU actually _trims_ the aircraft, I could follow that argumentation - but does it really work that way?

Activating SAU the aircraft stabilizes and flys level. Of course the stick should remain in the last position when SAU is cancelled. Thus no pitch change should occur. Anything else wouldn´t make sense. And how else should SAU control the aircraft? Trim is not performed by trim tabs, but by moving the joystick and thus moving the whole elevator and the ailerons.

 

Fly low level(50m height and altitude below 500m) with SAU activated and full mil power. When you have 1100km/h IAS cancel SAU.

 

And for the double trim bug check the video in this post.
