Under normal operating conditions, when an aircraft is in a banked turn, the rate-of-turn indicator is a valuable gyroscopic flight control instrument. When it is associated with an attitude indicator it indicates :
- the angular velocity of the aircraft about the yaw axis
- the bank of the aircraft
- the direction of the aircraft turn
- the angular velocity of the aircraft about the real vertical
