Fsuipc filter

[youyou]

hello

I am undecided regarding the filter option in the elevator section on fsuipc for my opencokpit yoke. I don't know what makes it more real between activated or desactivated and take in minde that the slop is at -1. when it is activated the reaction of the yoke is slightly slower and when it is deactivated it is more responsive.

My question is the following. in a real boeing 737 what is closer to reality between the 2 option 

Thanks

The Filter option only suppresses large fluctuations in short time frames. and is meant to be used if you have a jittery axis (some older/warn devices can send unwanted spikes in axis values). There should be no performance change when using this, so it surprises me that it is less responsive with this option enabled.

Having never flown a real boeing 737, I would not be able to answer this.

Cheers,

When i say less responsive i mean it s less sensitive.. like you slow down the yoke sensitivity.. but the yoke is very responsive.. it s like i added or remoove slope.

That is strange - filtering should in no way affect the yoke sensitivity- that is what the sensitivity curves/slopes are for, as you say.
What 737 and version of FSUIPC are you using?

You can try activating logging for Axes Controls and open the logging console window. If you do this and then move the elevator, you will see the elevator axis control/event logged, together with the value (the parameter), Try this with both filtering enabled and disabled - you should see the same value/parameter sent when the yoke is in the same position regardless of whether filtering is active or not.

If your elevator axes isn't spiking, there should be no difference.

I m using pmdg 737ngx with fsuipc 6

I made some research on chatgpt and here is the answer

Even if your flight hardware and potentiometers are stable and pose no problems, there may still be a difference between the two options (checking and unchecking the filter box) in terms of piloting feel and precision in the flight simulation  .  Here are some points to consider:

 1. Control Responsiveness: Even with stable hardware, unchecking the filter box can provide a more direct and immediate response from the controls, which can be noticeable in the steering feel, especially for fine adjustments and delicate maneuvers.
 2. Airplane Stability: Checking the filter box can help smooth out stick movements and make the airplane more stable by reducing harsh responses or jerks.  This can be beneficial for maintaining a consistent flight path, especially when cruising or landing.
 3. Simulator Sensitivity: How the simulator interprets hardware inputs can also influence the difference between the two options.  Some flight simulators may be more sensitive to filter box settings than others, which may affect the feel of the flight."

Thats interesting - and a reasonable sounding but completely made-up answer!
