Figure 32 - ADAHRS Cross-Checking Disagreement
Once SkyView has annunciated a cross-check comparison problem, press COMPARE to see both
ADAHRS side-by side. The ADAHRS that was previously displayed on the PFD is labeled
“ACTIVE”, while the one that was not previously being displayed - but which was being used as
the cross-check reference – will be labeled as “STANDBY”. Additionally, the labels “PRIMARY”
and “ALTERNATE” designate which ADAHRS is normally displayed when both are in agreement
and neither is disabled.
