System Overview Flight Instruments EIS CNS Interface GPS Navigation System Overview If the magnetometer input fails, the AHRS continues to output valid attitude information; however, the heading output on the PFD Page is flagged as invalid with a red 'X'. Failure of the air data input has no effect on the AHRS output while AHRS is receiving valid GPS information. Invalid/unavailable airspeed data in addition to GPS failure results in loss of all attitude and heading information. Likewise, loss of magnetometer (heading) data, in combination with loss of GPS data results in a loss of all attitude and heading information. 1.7 ACCESSING SYSTEM FUNCTIONALITY MENUS NOTE: Flight Log and Track Log must be accessed from the MFD in a Multiple Display system.
