Introduction: Turn Coordinators display the rate of turn and roll information, as well as quality and coordination of the turn. Turn & slip indicators only show rate of turn. Developed from the turn and bank indicator. This ball measures the relative strength of the force of gravity and the force of inertia caused by a turn. Ball bank indicator readings were correlated with lateral acceleration rates. Additionally, the influence of vehicular body-roll on ball bank indicator readings was investigated.Ontario traffic manual
