SSJ Issues

Postby Ivan-Pekar » Wed Oct 17, 2018 7:31 pm

Hello,
I have quite a few problems whilst flying the SSJ. Firstly, when in LNAV mode, the aircraft rolls rapidly from one side to the other, as if it cannot determine at what heading it needs to fly to the next waypoint. Please see video attached (it is in 2x speed). The same is with switching to V/S, but the aircraft changes pitch and V/S constantly. I have also noticed that, on the ground, there are some trails being ejected from the engines, that aren't present in reality. These are the issues that I can just recall now, but I'm sure there are more and I will report those later.

can you describe more about "some trails being ejected from the engines, that aren't present in reality." i'm wondering if they may be smoke from the exhaust but you didn't show any in your video...
"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."

Man.. that is a classic example of a TERRIBLY tuned AP...

If you want to fix it yourself, but don't know much about control loop tuning, perhaps try this

Kind Regards,

wkitty42, this happens when I put on full throttle (at takeoff), and a orange-coloured smoke gets ejected from the back of the engine, like a contrail.

Josh, thank you for the link!
