What does "control reversal" mean in flight control systems?

Control reversal in flight control systems refers to a situation where the aircraft reacts opposite to the pilot's inputs. This phenomenon can occur under specific circumstances, such as when the control surfaces are operating outside of their intended design parameters, or due to effects like adverse yaw or aerodynamic stall. For example, if a pilot moves the control stick to the right, instead of the expected right roll, the aircraft might roll to the left instead. This can lead to confusion and potential loss of control if the pilot isn't aware of the condition, as it contradicts the intuitive response expected from typical aircraft behavior. Understanding control reversal is crucial for pilots to maintain awareness of their aircraft's mechanics and ensure safe operation.
