A turn coordinator instrument indicates

• A. Bank angle and heading
• B. Yaw and airspeed
• C. Roll and yaw
• D. Pitch and yaw

Answer: (C)

The turn coordinator uses a slightly tilted gyro to sense both roll and yaw, giving two cues: how quickly you’re rolling into or out of a turn (roll rate) and how fast you’re actually turning (rate of turn, or yaw). The miniature airplane tilts with roll, and the movement of the needle shows the turn rate, helping you coordinate and anticipate the turn. It does not display exact bank angle, heading, airspeed, or pitch—the heading and attitude are shown by other instruments, and airspeed by the airspeed indicator. Therefore, this instrument indicates roll and yaw.
