What happens to the ball in the turn indicator if the airplane is climbing?

In the context of an airplane's turn indicator, the movement of the ball is influenced by the forces acting on the aircraft during maneuvers such as climbing. When an airplane is in a climb, it experiences a change in vertical lift, which affects the balance of forces. The turn indicator is designed to show the coordination of the airplane during turns; it includes a ball that moves in a curved glass tube filled with liquid.

When the aircraft is climbing, the center of gravity shifts relative to the forces acting on the aircraft. Specifically, in a climbing turn, the centrifugal force acts outward, pushing the ball towards the outside of the turn. This is due to the combination of the upward lift and the horizontal component generated by the turn, resulting in the ball moving outward from the center. This behavior helps pilots recognize their flight dynamics and maintain proper coordination during various maneuvers.
