SPRING TABS
The spring tabs are connected in such a way that elevator deflection in
one direction causes the spring tab to move in the opposite direction,
thus reducing the amount of force required to move the elevator.
Spring tab deflection is proportional to the control column force and,
therefore, to the aerodynamic load imposed on the elevator. At low
speeds, the spring tab remains in the neutral position. At high speeds,
where the aerodynamic load is greater, the tab functions as an aid in
moving the elevator.
