Ifdifferences in the sensors exceed a specified amount, the Comparator Windowappears in the lower right corner of the PFD and the discrepancy is annunciated inthe Comparator Window as a ‘MISCOMP’ (miscompare). If one or both of the sensedvalues are unavailable, it will be annunciated as a ‘NO COMP’ (no compare).CAS Messages (Comparison Alerts)If the ADAHRS source selection is set to Auto and an attitude miscompare conditionis detected, the flight director cannot be engaged until the pilot determines whichsource of attitude data should be used. When the pilot selects a specific ADAHRSsource other than Auto, the flight director and autopilot may be used (or re-engaged)even if the miscompare condition persists.AFCS ALERTS (OPTIONAL)AFCS Alerts
