SAU recovery oscillation

[WelshZeCorgi]

Is anyone else getting a pitching oscillation when activating sau recovery (the big black button on the right of the stick.)

 

It seems to get worse over time, seems like a bug.

Yes, I experienced the same during a flight issue last week. Unfortunately I don't have a trackfile of this flight. It doesn't always seem to happen though, just under specific circumstanced (loadout?, altitude?).

It’s happenned since the FM was recently adjusted

I had no oscillation with it today, but did notice it was putting me into a slight climb rather than its previous behaviour before the FM change (dropping the nose for speed, overcompensating once or twice to level out, then sitting dead level).

yes its terrible, is on their official bug tracker

I've had SAU recovery oscillate while trying to keep level flight, and I've had it put me in dives, and I've had it put me in climbs. It just doesn't seem to work as intended.

I am experiencing the same behaviour. It was fine in one training mission but after that it has hapened to me even in free flight.

[AeriaGloria]

While it may not be suppossed to oscillate, it is normal for it to cause altitude loss before leveling out in recovery mode. When it went up for you Nealius may you have been going transonic? If so might have been pitot errors

Use stabilize + attitude hold

Steady as a rock.

I have observed it as well, I think it's related to how well trimmed you are before activating recovery mode. You need to be well trimmed before activation IMO. Check it out.

This is a workaround, not a solution to the bug.

You don't have to be trimmed for it to work.

Pg.64 "If engaged, “RECOVERY” mode will try to recover the aircraft from any attitude to level flight. Note that recovery is not always possible."

There might be logic issues where if you want recovery at less than 750 km/h the ARU-3VM stick to surface oscillations might induce these oscillations in the sense that you would recover only at logically high speeds and not the full spectrum of the speed as thought before. I could be wrong.

 

My point is, accel to >750 km/h and you may experimce less oscillations as the system intentionally deflects LESS with high speeds and more with low speeds.
