Hello
I have the following problem:
When disengaging the autopilot, the control wheel violently „resets“ ist position to neutral. This is especially a problem for me when using a force feedback yoke.
You can verify this when testing the a/p on the ground. Like in a real airplane in active HDG mode the yoke (the aileron servo) follows the heading bug. A press on the „A/P disengage“ button would disengage the servo and the aileron „axis“ would be exposed only to its „natural“ forces again (none at the ground) what means it would stay in the last position. In the sim though it „jumps“ back to „neutral“ instantly, what is wrong.
I fly mostly Blacksquare Dukes and the TBM. Same behaviour there.
Is this already known as a bug or is something wrong with my installation or configuration?
Thanks in advance for any hint.
Not sure if this is the same issue. I’m not using a force feedback yoke so I can’t comment there. but let’s say from takeoff and initial climb I have the elevator trimmed. Once I turn on the autopilot and it takes control of the elevator trim It doesn’t change the physical setting of my trim wheel on my Flightstick, so when I disconnect the autopilot on approach (or generally whenever) the trim resets to my last position to match my physical trim wheen which usually results in some pretty aggressive nose down pitch (which is fun on final)
I think this case is a limitation of the sim and/or hardware. In the real plane the trim is moved by the autopilot and whenever you disconnect the trim is in the last position that the autopilot set it, and you just take over from there there is no disparity between the autopilot and yoke in the real plane like there can be between the digital sim and physical flight controls we use…
This is all just a guess from my end, my work around is to set the trim using my trim wheel while the autopilot is still active. If I move the trim wheel it’ll pitch up or down and the autopilot will correct. I just keep trimming until there is no noticeable change in pitch when I move my trim wheel. Then when I disconnect the AP my physical trim and the digital trim in the sim are matched. Annoying but workable
It sounds like the same issue to me.
What you do manually (adjusting the elevator trim to neutralize forces) is what you do when flying manually or when using an autopilot without a trim servo installed. In earlier days this was the case sometimes. An illuminated or flashing light “TRIM UP” or “TRIM DOWN” urged the pilot to follow the A/P inputs with the trim wheel manually when the A/P reached its “authority limit”. In this case disconnecting the autopilot (in flight) could result in abrupt forces on the elevator when your manual trimming was not perfect. Not so much on the ground (there is only the weight of the elevator surface pulled down by gravity) and never on the aileron axis (like in the sim).
Nowadays (and what is simulated here) there are elevator trim servos “installed” and you would expect a perfectly trimmed out airplane when disconnecting the A/P.
Yes it’s simulated in the sim. But for me it cannot move my trim wheel on my Flightstick so it’s left in whatever position it was in before I engaged the autopilot. If I could have the sim move my trim setting (it is just a digital input) then this issue would disappear and it would be just like real life. A trimmed airplane when you disconnect to hand fly
Ok, I understand what you mean. You have an “analog” axis assigned. You could try to unmap this axis and map buttons like a trim switch to see if that improves the behaviour. But I doubt that.
I have the VirtualFly TRIMS neo. The trim wheel there sends incremental “button presses” and is not an axis. I have the same odd behaviour - thats why I posted here.
But my post and title were a bit wrong anyway. I just saw the same behaviour on default aircraft. So it is an Asobo issue, sorry Blacksquare! It seems that Blacksquare did not implement all systems from ground up. That’s what I thought.
Is there any way to contact and discuss this with them? All I get from the Justflight support email-addresses is this: “Security or policy settings at justflight.com have rejected your message”.
I believe Black Square is a solo dev, not sure how to contact him directly.
This behavior happens to me on every plane so I believe it’s a limitation of the sim/my hardware.
