True Blue Power Turn Coordinator

1394T101-3B Lighted Turn Coordinator

Brushless, panel-mounted turn coordinator designed to display combined rate-of-turn and rate-of-roll information as a rotating aircraft symbol, aiding pilots in performing standard-rate turns and maintaining control in partial-panel IMC conditions. Offering the same core functionality as the 1394T101-7B in a lighted configuration.

The instrument includes a fluid-damped ball-in-tube inclinometer for slip/skid indication. Featuring a lighted bezel, accepts 11–32 VDC input, and uses a 3-pin connector, making it a straightforward replacement for a wide range of legacy turn coordinators.
