Patent ID: 8073580

Claim:
An augmented air data and inertial reference system (AADIRS) serving as a standby instrument on an aircraft, comprising: a secondary air data and inertial reference system (ADIRS) including a secondary air data module coupled to a secondary inertial reference module, the secondary air data and inertial reference system configured to derive secondary air data and inertial reference data using the secondary air data module and the secondary inertial reference module, the secondary inertial reference system further configured to provide the second air data and inertial reference data to a flight control system for use as a backup source of data for control of the aircraft; and a graphics module coupled to the secondary air data and inertial reference system and a display, the graphics module configured to receive the secondary air data and inertial reference data and process the secondary air and inertial reference data to generate graphics data, the graphics module further configured to provide the graphics data to the display to generate backup instrumentation on the display, wherein the secondary ADIRS and the graphics module are configured to provide graphics data to a main display panel to generate backup instrumentation on the main display panel along a signal pathway independent from a primary data bus of the aircraft.
