Abnormal Operations
9.3.5 Miscompare & No Compare
AHRS/ADC SENSOR COMPARISON
The GDU continuously monitors and compares sensor data when more than one
AHRS or ADC is present. A miscompare state occurs when the difference between
two or more sensor outputs is above the predefined threshold.
[1] Depends upon configuration.
MISCOMPARE ANNUNCIATIONS
Miscompares generate a caution annunciation over the affected PFD instrument(s).
In addition to miscompare monitors, the GDU provides an independent flight
dynamics monitor that compares computed cross heading, vertical accelerations, and
roll angles against reported values generated by the AHRS. If there is a disagreement
between the flight dynamics monitor and the AHRS parameters, the “ATTITUDE”
caution annunciates.
