CAT 2 ANNUNCIATOR
PFD With CAT II Annunciations
Figure 4--21
The green CAT2 mode annunciation is an indication that the
conditions for a CAT2 approach are present and the excessive ILS
deviation monitors are active on the PFD.
The symbol generator activates the CAT2 mode annunciator on the
PFDs whenever APR (approach) mode is selected and the following
criteria are satisfied.
-
The DC RA set data must be set to between 200 and 100 feet and
both radio altimeters must be valid, and indicating greater than
1000 feet.
-
Independent and valid navigation sources are present on pilot’s
and copilot’s PFDs.
-
The on--side radios must be selected for display, both must be
tuned to the ILS, and the localizer and glideslope deviations must
be valid.
-
Attitude and heading must be valid on both PFDs.
