What type of gyroscope does the turn coordinator use?

The turn coordinator utilizes an electrical gyro. This type of gyro operates with a rotor that is spun by an electric motor rather than relying on the principles of inertia or the external air pressure that influences a vacuum gyro. The electrical gyro provides rapid and precise response to changes in the aircraft's orientation, which is essential for accurately displaying turn rate and coordination information to the pilot.

In addition to its electrical mechanism, the turn coordinator is also known for its ability to indicate both rate of turn and coordination, meaning it shows whether the aircraft is in a coordinated turn or if there is a need to apply rudder input to achieve better balance during the maneuver.
