Lays down the characteristics for a 4 MCU integrated digital Air Data and Inertial References System (ADIRS) which is meant for installation in subsonic commercial transport aircraft. It is thought that the ADIRS will incorporate the capabilities of both an air data system and an inertial reference system. Provides general and specific design guidance for the development of an ADIRS for the use of airlines.
