There is a fix by @hbeni to the KAP140 on the c182s/t. All that is needed is to test and merge the newly created PR. It needs to be tested by someone familiar with KAP140 operations before merging.

Did it and documented it at the PR: looks good for me

I sourced a ticket regarding variations in the static pressure signal when the mouse LMB is pressed off-window. The c172p seems sensitive to variations in that signal which is differentiated to yield ROC. Too, the elevator PID seems to be doing a double integration using elevator to respond to target ROC.
I've posted a modified KAp140.xml at: www.bitwisetech.com/fgfs/c172p/Systems/KAP140.xml: the elevator drive is split into two PIDs with target pitch as the intermediate signal. Gating for signal injection ( keyboard hotkeys ) for each stage is left in place, I'm looking at wing droop at lower airspeeds. The filter for derived ROC has and increased time constant. Season's best wishes.

I think we can close this ticket: Will be superseeded by #1302 Upgrade KAP-140 to new version
