Attitude and Heading Reference Systems

Abstract

This test operations procedure (top) presents test methods to evaluate the technical performance of heading reference systems that meet criteria specified in applicable required documents. New universal heading reference systems are continually being developed and improved to meet new and existing requirements, with an all weather capability, for military and commercial aircraft. The heading reference system provides an accurate determination of aircraft heading relative to true north. This is accomplished by use of a magnetic compass and/or a gyro compass, depending on the region of operation. Engineers and other personnel engaged in testing and evaluating aircraft systems have developed certain procedures of testing over a long period of time. These procedures, properly used, can aid in determining the acceptability of heading reference systems for an intended use. The reference system must adhere to user (Government) and manufacturer's specification to be accepted. This TOP is limited to heading reference systems of the directional gyro type.
