摘要：	This report provides an assessment of technical and production risks of candidate low-cost attitude heading reference systems (AHRS) for use in the Advanced General Aviation Transport Experiments (AGATE) airplanes. A low-cost AHRS is a key component of modem 'glass cockpit' flight displays for General Aviation (GA) aircraft. The technical capabilities of several candidate low-cost AHRS were examined and described along with the technical issues involved with using all solid-state components for attitude measurement. An economic model was developed which describes the expected profit, rate of return, and volume requirements for the manufacture of low-cost AHRS for GA aircraft in the 2000 to 2020 time frame. The model is the result of interviews with GA airframe manufacturers, avionics manufacturers and historical analysis of avionics of similar complexity. The model shows that a manufacturer will break even after three years of AHRS production, realizing an 18 percent rate of return (23 percent profit) on an investment of 3.5M over the 20 year period. A start-up production estimate showed costs of 6-12M for a new company to build and certify an AHRS from scratch, considered to be a high-risk proposition, versus 0.25-0.75M for an experienced avionics manufacturer to manufacture a design under license, a low-risk proposition.
