Our RCA1510 Series Digital Heading Indicator is the latest addition to the RC Allen Digital Instrument Lineup.
It is the perfect companion to the RCA2610 Digital Attitude Indicator. The RCA1510 is designed as a fully FAA Certified direct replacement for your mechanical Directional Gyro. It is totally self-contained and fits in a standard 3-inch panel cut-out. There are no special external connections other than power and an external GPS antenna. The Multi-Volt function allows installation in both 14 Volt and 28 Volt systems. The RCA1510 combines data from its own internal magnetometer and GPS receiver for a more stable and accurate heading reading which also eliminates the need to “cage” or “zero” the instrument. Because the RCA1510 has no mechanical gyroscope, it is much more accurate than traditional heading indicators. Unlike a mechanical gyroscopic unit, the RCA1510 is not affected by drifting or wandering. The unit is designed to work without GPS input if the GPS signal is lost. The highly visible screen has adjustable brightness controls. It has a traditional rotating dial display with digital numeric headings. The pilot can adjust the Heading Bug just like a mechanical instrument or use the Quick-Set Heading Bug; a double-push of the HDG knob sets the Bug to the current heading.
The heading indicator (also called an HI) is a flight instrument used in an aircraft to inform the pilot of the aircraft’s heading. It is sometimes referred to by its older names, the directional gyro or DG. The heading is indicated on a display, which consists of a circular compass card calibrated in degrees. A heading marker (bug) is used to mark on the dial the desired heading which is set by turning a knob on the front of the instrument. It is a primary instrument for flight in IMC (Instrument Meteorological Conditions). Heading indicators also have significant applications under VFR (Visual Flight Rules). The RCA1510 Electric Digital Heading Indicator utilizes an internal magnetic compass to determine aircraft heading. In flight, GPS information is added for a more stabilized and accurate heading reading. With a GPS signal, the RCA1510 acts like a “Magnetic Track” instrument. It is permissible to install the RCA1510 without a GPS signal and utilize the instrument exclusively as a “Magnetic Heading” type indicator (See Section 3.5).

NOTE: There is an extra charge to re-set the tilt angle after purchase.
