Autopilot trim & vs

Asobo!
Are you going to fix already autopilot in this game or not?
On every aircraft I fly when I engage autopilot it tries to kill me!
Trim is instant on max nose up and VS goes up to 10.000 ft/min, air speed drops and I get in to stall.
After numerous tries to engagne AP I make it stable.
Is it so hard to make things work like they should?

Also, I don’t know why it is happening, but every aircraft I fly it’s banked few degs to the right. Fuel is even in both tanks, joystick axes are calibratet to mid, settings in control are set to mid, this is happening after update where you changed sensitivity settings.

P.S. Why you can’t make something work and not mess it in next patch. How would you feel I build house for you and not make doors and windows, than I come again and make doors and windows, but I take off the roof, after fixing the roof, I cut of water. I payed something and I want it to work! Not to have stress every time I want to have some fun!

Have you checked for duplicate commands on your flight control surfaces?

This is certainly not the response I get when I engage autopilot. I always make sure everything is stable before engaging AP, and that I have several hundred feet of clearance to the terrain, as the nose does dip slightly, but then recovers immediately.

A few more details would be useful. What plane are you in? At what point does yours go nose up, eg when you first switch on AP, or when you engage ALT etc?

The banking to the right does sound like a hardware problem, as it’s in every aircraft. What peripherals are you using?

Do you know, many of the problems that people are experiencing are NOT the ‘fault’ of the simulator!!!

Made any changes?
Used any mods?
Got any controller issues?
Cleared your community folder, every time, before patching?
Got out the wrong side of the bed?

Sorry, skip that last one!

Change the flightmodel to modern and all will be fine.

If its not this setting i would take a second look at you controller hardware and bindings. Maybe there are double bindings or your joystick/yoke are defect and give steady input even if your not touching it. This can be probably mitigated with increasing the deadzone.

I use mods but only scenery and some aircraft, nothing else. This happens in all aircraft.
Should controller affect AP VS rate? Because only way I set VS is by mouse on dashboard.

Flightmodel is on modern.

Sure it can. The AP set trim to maintain your AP settings. When you provide a small but steady input, i.e. you pull the yoke slightly the whole time, AP is moving trim further to compensate your input. That is going further and further and at a certain point, AP loses control and disengage and then you’re done, because trim is at the very end. Maybe I’m wrong but you can check by yourself. Take a look at the trim settings when it happens.

I just read your initial post again, and if it’s not the flightmodel I’m quite sure that there is something wrong with your controllers.

Yes.
And apologies re my flippant, earlier remark.

Your AP related issue is clearly real and no doubt very frustrating!
Given then the, on my part, [reasonable] assumption that the cause is at ‘your end’, the
problem shifts to one of finding the cause.

Sunday784 is likely your best guide here.
Beyond that, the answer is probably to be found buried somewhere in these forums.

Good luck.

@vedran136.
I experienced something similar and in my case the controllers were to blame. I use a Thrustmaster T16000M joystick and Throttle including pedals.

  1. When fiddling with the settings save them under a descriptive name. This way you can have a tailor-made setup for each aircraft and that makes life easier. The Airbus is hardly flyable with the same setup as the Cessna 152.

  2. Adjust the dead zone for all spring loaded input devices (stick and hat switches). Default is 1%, but you may need 2-4% to stop it interfering with the aircraft. I had a problem with the camera constantly creeping downwards, until I changed the dead zone to 2%. Same cure for the pedals.

  3. On other devices (throttle lever and elevator trim) set the dead zone to 0% as there is no mechanical midpoint. It is just a simple potentiometer.

  4. When beginning a new flight, syncronize your controllers!
    The sim and the controllers are not in sync, and this goes specifically for the elevator trim. Move them up and down, left and right and leave them in neutral position. Do not forget rudder and aileron trim. Default aileron trim for the TBM930 is -0.2 forcing the aircraft to immediately bank right. I use 0.0.
    When airborne - and before activating the auto pilot - trim your aircraft for a straight flight path. This will prevent the unexpected to happen when you later disengage the auto pilot for landing.
    Remember, the auto pilot does NOT adjust the trim controls - you do!

That’s a good point. Use the checklist and you have the Item: Check Flight Controls
Do it, check the flight control on all axis. I found out, that my TM Rudder Pedals need one complete cycle to synchronize with the rudder. If I don’t do it, i have full rudder deflection with just 1/4 of pedal deflection. After completing a full cycle everything is fine then.

Maybe I understand you wrong, but the AP do control and adjust trim. You can see it clearly when you look on the trimwheel during AP controlled flight.

You are right, sorry for not making myself clear. Trying again:
If the aileron trim device is not in sync with the sim, you may end up in a situation where you lose control, because the device is at the endstop.

I’m taking an extended break now. I have 20 + years experience simming but the basics are not fixed. Even something as small as trim. It works thrn ugh… doesn’t…

Hello,

using DA40 with icing conditions under AP, the aircraft try to keep altitude till reaching maximum trim and then stall as speed goes down. In that case you reach trim limit and then if you try later to re-engage AP then the aircraft try to climb at an insane rate and I don’t know how to re-sync the trim at that stage other than relaunching the sim entirely …
