[BUG] - Elevator "jump" after flaps&slats UP, when you pull nose up #1707

Open joon44 opened 3 months ago

Describe the bug

From Discord user teropa: "I observe after cleaning up flaps and slats, an amplified nose up effect as you pull the yoke a little for setting proper acceleration attitude. Small pull input makes the nose come up on its own very fast. This is either LSAS or some other at play. I don't know if it's a bug but it seems strange."

Steps to reproduce

After takeoff clean the wings, observe uncommanded elevator movements

Expected behaviour

Cleaning the wings not to amplify pitch up movement

Evidence
