- Definição1
- A rate gyro flight instrument that gives the pilot an indication of the rate of rotation of the aircraft about its vertical axis. The turn and slip indicator shows the trim condition of the aircraft and serves as an emergency source of bank information in case the attitude gyro fails. The turn indicator uses a rate gyro attached through a fork and pin mechanism to a vertical pointer. This rate gyro is installed so it measures the rate of rotation about the vertical axis of the aircraft. The vertical pointer shows when a standard rate turn (3º per second for some aircraft, and 1 1/2º per second for others) is being made. The slip indicator is a curved glass tube partially filled with a liquid in which a black glass ball rolls. When the angle bank is correct for the rate of turn, centrifugal force and gravity are balanced, and the ball stays in the center of the tube. When the rate of turn is too high for the angle of bank, the centrifugal force is greater than the force of gravity and the ball rolls to the outside of the turn. When the rate of turn is too low for the angle of bank being used, the force of gravity is greater than the centrifugal force, and the ball rolls to the inside of the turn. Turn and slip indicator were once called needle and ball indicators and more recently, turn and bank indicators.
