@Lixma 06There's one more switch you need to turn on. In the front cockpit on the weapons panel (right side of the dashboard) you need to turn on CPLR DISTR switch (middle one in the upper row). That unit provides ATsVU (analogue-digital ballistic calculator) with data from different sensors — attitude, speed, altitude, and so on.

The AP behavior when trim button is pressed is bugged currently, which was acknowledged by devs and few real world pilots over at the russian side of the forums.

To trim you do not need to press button, move stick, and then release it, like in Ka-50. It doesn't really matter, when you pressed the button, only when you released it. So, in this regard it should be operated just like in Mi-8 — move the stick and then click trim button.

But, at the same time, AP in Mi-8 and Mi-24 work differently. In Mi-8 AP is not connected to trim in any way, so from AP point of view it doesn't matter, whether you just moved stick into new position, or trimmed it there. In this helicopter AP will always try to correct a little towards position, in which cyclic was, when AP was turned on. To have maximum AP authority in the new stick position you need to manually adjust knobs on AP panel, so that all the bars on the indicators are centered.

On the other hand, in Mi-24 AP is connected to trim mechanism. When trim button is pressed, AP centers at this new cyclic position automatically, so it has maximum authority for compensating any possible deviation. Unfortunately, right now in the sim this process is bugged. When you press the button, AP centers on the new position, but when you release it, AP just goes back to the old position, which is incorrect. That causes helicopter to move it's nose a little towards the position, in which AP was turned on. And that's why right now trimming causes unintended movement.

So, we just have to wait for a bugfix. Hopefully, it'll not be long.

P.S. The hat-switch trim works independently of AP. It does not recenter AP, so it actually works as intended in the sim. You can use it for smoother control instead of button trim.

Do you have Airspeed to Doppler switch off on left panel? I'm not entirely sure, what it does, but it seems to mess up DISS.
