What should the Turn Coordinator ball indicate when the aircraft is in a straight flight?

• A. Ball concentrated in the center
• B. Ball outside the turn
• C. Carried to one side
• D. Would show no indication

Answer: (A)

When an aircraft is in straight, level flight, the Turn Coordinator should indicate that the ball is concentrated in the center. This is because the ball in the Turn Coordinator is part of a gyroscopic instrument that measures the coordination of the aircraft during turns. In straight, unaccelerated flight, there should be no lateral forces acting on the airplane, resulting in the ball being centered and indicating a balanced condition. When the aircraft is properly coordinated in a turn, the ball will be centered as well, confirming that neither the wings are excessively banked nor are there any lateral accelerations acting on the airplane. This central position of the ball indicates that the pilot is managing the turn appropriately without slipping or skidding, maintaining a proper flight attitude.
