TURN COORDINATOR

3D Model

They both have gyro mounted horizontally on a gimbal and electrically operated. -They both work under the principle of precession. -They both have inclinometer, a sealed curved glass tube filled with liquid and a black ball, that measures the quality of turn. When you make a left turn for example and the ball is on the right, then it’s skidding; when on the left, it’s slippering. It should always be centered during airborne operations. -They both measure rate of turn, 3°/sec, making 2mins to complete a 360° turn. But the turn-and-slip indicator measures turn around the vertical axis only while the turn coordinator measures around longitudinal axis cos it’s gyro is mounted 30°above the longitudinal axis of the airplane.
