Such Innovative Technologies Have Become Commonplace In GA You know that they're there -- but you rarely see them -- the tiny little boxes that provide the physical guidance for today's ingenious generation of glass panel cockpits. Solid-state by design and bereft of the hundreds of moving parts once associated with gyros and their support systems, the modern AHRS is a dependable, and superior replacement for the vacuum pumps and gyros of old. Known by a variety of similar names, the modern AHRS is an all-electronic Attitude and Heading Reference System that combines the functions of a Vertical Gyro and a Directional Gyro to provide measurement of Roll, Pitch, and Heading (Azimuth) angles. Aero-TV took a little time at the recent 2009 AEA Convention to get an AHRS education from one of the leaders in the field... Crossbow Technologies. Founded in 1995, Crossbow pioneered the use of Micro-Electro-Mechanical System (MEMS) Inertial System technology in a wide variety of airborne, land and marine applications. Crossbow first introduced FAA-certified MEMS-based Attitude and Heading Reference Systems (AHRS) to General Aviation on the FAA Capstone program, and the company continues to be at the forefront of AHRS and Inertial Systems development. With corporate headquarters in San Jose, CA, and Asian offices in Tokyo and Osaka, Japan, Crossbow has distributors in 24 countries worldwide. Crossbow is ISO 9001/2000 certified, holds several FAA TSO approvals, and operates an FAA MIDO approved facility.
