today I flew a little with my Arrow and experienced something strange:
at cruising speed with the AP turned to HDG and ALT the aircraft started vibrating noticeably which turned pretty annoying after a while. First I though it might have been the new update to 0.3.0 because it was the first time I flew with that, and never had those vibrations before. I also changed to the Mooney mid-flight and there it was gone with the same settings. Then I started a new flight with the Arrow again and as soon as I turned on ALT it started again. No problems without ALT hold.
I am aware that the altitude hold function is only there for out convenience, since the real AP of the old Arrows didn’t have it, but still it’s a little annoying. Anyone also have that problem?
Yes. Had her trimmed at 3500. Tried it several more times at different altitudes and speeds. Everytime I engaged Altitude Hold the vibrations started and where gone the moment I deactivated it.
Yes, it vibrates with alt. hold. HDG or NAV only, and it won’t. To be fair, it’s not supposed to have that function anyway, but since they added it then it should work. I assume it’s because the trim is being adjusted more rapidly than it needs to. Mouse over the trim wheel next time you use it
Yep, I have it also. Very noticable when looking out the front but looking left or right I don’t notice it. I also get a screen jump when I start to taxi from a stopped situation.
Managed to replicate and had to go well above 130kias (started to be noticeable above 140kias) to see this high frequency oscillation in pitch. altitude remains constant but the plane vibrates brrrrrrrr.
definitely something wrong, even though I usually cruise below 135kias, but it needs a fix anyway.
Just open a ticket to their support to make sure it gets fixed.
I saw this effect also but it disappears if I reduce the speed a little. Basically happened only if I go full throttle
Me too! I assumed it’s because I had adjusted the default camera positions for the pilot camera, so perhaps not. The pilot position jumps up a bit as you start to taxi.
It’s up to everyone to decide if the want to use a feature that this addon provides, don’t you think?
And since it’s a feature, it’s totally correct to report issues with it.
You can trim it for smooth air, but when you encounter turbulence, you’ll get thrown around. If you need to hold altitude, for example ATC instruction, then altitude hold is invaluable.
No one suggested trimming was difficult, it’s quite easy, and this plane is very stable.
