Advanced circuitry and improved design allow this directional gyro to withstand high vibration and require less than half the power of standard DGs. Lightweight (1.8 lbs.) and reliable, it utilizes long-life LEDs for a crisp, legible backlit display. With 10–32 volt DC input, it will work in any aircraft. Exceptional RTCA DO-160E HIRF immunity makes this an ideal replacement for heavy, older AIM and RC Allen units.
