Data hybridization computation analysis of aircraft air data inertial reference system

Air data inertial reference system (ADIRS) receive the data from air data unit, inertial reference unit and global positioning system which hybridizing out the basic flight parameters. After giving the examples of accidents causing from ADIRS output data, the hybridization computation of basic parameters is analyzed, and give the new opinion of hybridization computation considering pitot probe fault, for getting more accurate data and avoiding accident.
