ELECTRIC DG’s
15EK-1
NEW MULTI-VOLT DIRECTIONAL GYRO INDICATOR
The RCA 15EK Series is the newest innovation from R.C. Allen. This is the perfect companion to our popular RCA 26EK Series of attitude indicators and has the same reliablility as the RCA 16AK and 15BK Series of directional gyros but with the additional EK Advantage!
The Multi-Volt gyro and lighting feature of the EK Series allows for an operational range from 10VDC to 30VDC.
the RCA 15EK is a fully univeral instrument. It is designed to be used in any type of aircraft whether it has a 14 volt or 28 volt electrical system. In case of a loss of power, the 15EK will keep running down to 10 volts.
RCA 15AK AND 15BK DG’s
The RCA 15AK (14 volt) and the 15BK (28 volt) Series of directional Gyros are still the dependable instruments that they have always been but they will eventually be phased-out in favor of the new RCA 15EK models. See our Catalog for details.

VACUUM DG’s
11A-8
RCA 11A SERIES VACUUM DIRECTIONAL GYRO
The RCA-11A series of vacuum directional gyros utilizes an air driven precision gyro that controls a vertical rotating azimuth gimbal. The R.C. Allen Model RCA11A has been designed to provide years of accurate operation even when subjected to severe operating requirements. This instrument is engineered with a minimum of machined parts, providing lower initial cost and lower maintenance cost throughout its lifetime.
The 11A-8F has a vacuum failure flag when vacuum has dropped below 3.5 inch Hg.
The RCA11A is non-tumbling within +85° limits in pitch and roll and can be easily installed in any 3 1/8″ standard panel cut out. Full freedom design allows for accurate indication, even after extreme maneuvers. We use stainless steel at critical wear points, along with aluminum investment and die castings for longer instrument life.
RCA 11D SERIES HEADING BUG & AUTOPILOT
The RCA 11D Series is our autopilot model for vacuum directional gyros. Their rugged design will give you years of reliable service.
CHOOSE FROM:
RCA 11D-4 Single Pointer Bug/400Hz Autopilot.

Be sure to check with your area distributor for compat-abilty.
TURN COORDINATORS
82A-11
RCA 82A/83A 3″ INDICATOR
Our turn coordinator is very popular and can be found in many production aircraft around the world. It contains an electrically driven gyroscope which is supported in a gimbal inclined to the horizon so that the instrument senses roll as well as yaw. The RCA 82A/83A Series is an all-volt instrument that works from 11 to 30VDC. The turn motion is presented by an airplane symbol banking on a fixed horizon with a power warning flag.
TURN AND BANKS
RCA 56 SERIES 3″ TURN & BANK
56-3B
Our popular RCA 56 Series Turn-and-Bank is a rate-of-turn pointer controlled instrument which is powered by an electrically driven DC precision gyro. Along with it’s built in inclinometer, It gives the pilot accurate turn and bank information. The RCA56 series is an all-volt instrument that works from 11VDC to 30VDC. This is a 2-minute turn instrument which features a power warning flag, your choice of either a black or white inclinometer ball and comes as lighted or non-lighted.

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.
