Which instrument aids in making coordinated turns?

• A. Indicated altitude.
• B. Measures airspeed.
• C. Provides standby attitude.
• D. Aids the pilot in making coordinated turns.

Answer: (D)

Coordinated turns rely on an instrument that shows how fast you’re turning and whether you’re slipping or skidding. The turn coordinator provides exactly that: it indicates the rate of turn and includes a slip/skid indicator (the ball) to show coordination. By keeping the ball centered and matching the turn rate to the desired bank, you can balance with the rudder to maintain a coordinated turn. Indicated altitude, airspeed, and standby attitude measure other aspects of flight and don’t directly help with turn coordination, making the turn coordinator the instrument that best aids this task.
