Auto-pilot VS asymmetric load

[jojo]

Mirage F1 CE, single-player, multi-threaded version, latest Open Beta.
Take with one fuel tank, 2*Magic, 2*Super 530F.

Shot 2*Magic & 1*Super 530F.
Left Super 530F remaining. Aircraft trimmed when engaging the AP, I cut the throttle to slow down.

Flaps retracted, the AP (PA + ALT) can't handle the asymmetry below 350kt (start banking left). Below 300kt It's becoming wild, it's over-banking to the right then to left and AP fails.
In landing configuration it seems to happen at slower speed, but it fails before reaching final approach speed.

I don't think it's an acceptable behavior for an all weather interceptor with such advanced auto-pilot.

[Edit]
Actually, even with symmetrical load the AP tries to kill me.

6 000ft, trimmed and level, 300kt. AP + ALT: it can be fine or it can randomly bank left/ right more than 60° then disengage.

I can't provide a short track because I can't identify the triggering cause, it happens randomly.

Hi @jojo,

Asymmetrical payloads will undergo another round of testing by SMEs. Regarding your second message, this problem has been fixed internally.

After spending more time on it, I can't say if the problem is asymmetrical load or just the unwanted roll in basic AP mode ?
When it does happen, it's like the control loop is "diverging", when the AP finally disconnect, if the plane is rolled on one side, the trim is unrolled to keep this position.

So maybe if you fixed that already, it will be OK with asymmetrical load ?

Hi @jojo,

If you're noticing the commands diverging from the target value, then yes it's that bug. If on the contrary, the controls are fighting the asymmetry, then it's just lack of authority (which we will review anyway). Another test you can do is to engage the AP with more than 10° of bank and see what happens, as the bug only affected the heading hold mode.

Hello, I have the same problem that Jojo has even with symetrical load. I have this problem on the CE and the EE. When the autopilot is engaged, and with any function of the AP, the F1 goes into a roll on the left without reason.

I have this problem on the multithreading version but also on the non multithreading version

I am on the open beta version 2.8.5.40170

Hi, it's been fixed, will be available to the public very soon.
