RCA82A/83A Series Turn Coordinators
$1,351.25 – $1,466.25
This instrument contains an electrically driven gyroscope supported in a gimbal inclined to the horizon so that the instrument senses roll as well as yaw. The RCA82A Series is an all-volt instrument that works from 11 to 30 volts DC. The movement is presented by an airplane symbol banking on a fixed horizon with a power warning flag.
Our turn coordinators are very popular and can be found in many production aircraft around the world. They contain an electrically driven gyroscope which is supported in a gimbal inclined to the horizon so that the instrument senses roll as well as yaw.

TURN FACTS
A turn-and-slip indicator will sense rotation only about the vertical axis of the aircraft. It tells nothing of the rotation around the longitudinal axis, which in normal flight occurs before the aircraft begins to turn.
A turn coordinator operates on gyro precession, the same as the turn indicator, but its gimbal frame is angled upward about 30° from the longitudinal axis of the aircraft. This allows it to sense both roll and yaw.
The inclinometer or “coordinator ball” shows the relationship between the bank angle and the rate of yaw. The turn is “coordinated” when the ball is centered. The aircraft is “skidding” when the ball rolls toward the outside of the turn and is “slipping” when it moves toward the inside.
