For General Aviation aircraft, the Attitude Indicator, Directional Gyro, and Turn/Bank Indicator are the three primary instruments that are Gyro driven. Crossbow's solid-state MEMS AHRS systems are single devices that provide necessary input data to drive all three of these instruments. The Crossbow AHRS is ideal for incorporation into current and next generation glass cockpit systems, autopilots and standby instruments, and gyro retrofit and replacement systems.
