Turn And Slip Indicator
What is turn and slip indicator?
The turn and slip indicator is a rate gyroscopic flight instrument that shows the pilot how fast the aircraft is rotating about its vertical (yaw) axis. It combines a turn rate needle (driven by a gyroscope) with a ball that shows whether the turn is coordinated, slipping, or skidding. Think of it as your "rate of turn plus quality of turn" gauge—step on the ball to stay coordinated.
Also known as: turn and slip indicator, turn-and-slip indicator, needle and ball, turn and bank indicator
