Ball bank indicator

moving vehicle, the reading from a ball-bank indicator represents the combined effect of vehicle body roll, superelevation, gravity, and lateral acceleration angle. A manual or electronic ball-bank indicator can be used. The ball-bank indicator used for curve testing should be capable of measuring inclination to at least a1-degree accuracy.

For example, when the ball is displaced to the left, this informs the pilot that left rudder input is required. The bank angle information is provided either by a miniature aircraft or a vertical line that rotates in the direction of the bank.
