X_legio Posted October 24, 2021 Posted October 24, 2021 Somethimes, during the flight and manouvers suddenly the Ka become strange to flight. I see that the Altitude holding AP is turning on by himself. I switch it off and all comes back to the normality. It's normal? During the hovering for me is very hard to keep it steady. I decelerate to 10kmh and engage the auto hover but often I continue to drift forward of side, very slow because the hud sign 0kmh... Did i make some mistakes ? TY guys
jubuttib Posted October 24, 2021 Posted October 24, 2021 On the hover situation: This can easily happen if you engage auto-hover while not already trimmed for a decent hover. The auto-hover functionality uses the normal autopilot systems, and as such is limited to IIRC around 15-20% control authority, i.e. it can only use about 20% of the range of the cyclic etc. that you can. Sometimes this means that if you're not already near a hover trim, the AP system can't move the controls enough to maintain a steady hover. If this happens, push in the trim button, try to get as close to a stable hover as you can, then let go of the trim button. If you're already near a stable hover, the AP doesn't have to work as hard to maintain it. 1
X_legio Posted October 30, 2021 Author Posted October 30, 2021 Ok clear... And why the Altitude AP sometimes engage by himself ?

You're drifting in auto hover because of the wind. Trim so you lean into the wind. Better Smoke - Better Trees Caucasus - Better Trees Syria - Better Trees Mariana - Clear Canopy Glass

Trim so you lean into the wind. Relates to the above point, the auto-hover will try to keep you steady even in wind, but it might run out of control authority. Trimming closer to a hover helps with this too.
Frederf Posted October 31, 2021 Posted October 31, 2021 "auto hover" is probably best translated as "hover hold". It will keep you in an established hover but almost never bring you into a hover from any other condition. It's important to be in the hover both physically as well as the control position appropriate for continuing the hover. Usually this means you want to hold the hover manually for a few seconds before trimming and engaging the hold. The ALT channel auto-engages whenever hover hold is engaged.
