2.8.6 Miscompare Annunciations
Miscompare annunciations are capable of being displayed on the PFD if the
miscompare Monitor is enabled during the installation configuration.
Messages will appear in the MFD alerts window if monitors are enabled and
required data is not present.
A miscompare condition is triggered if the difference between the data
reported by GDU 1 and GDU 2 exceeds the threshold described in the following
table for at least one second:
Parameter Range of Trigger Threshold
