CATEGORY II
ANNUNCIATOR
Refer to Figure 4.2.7 while
reviewing this section.
o
An optional annunciator pro-
vides advisory only information,
selectable at the time of installa-
tion and certification. When con-
figured, the symbol generator will
monitor the appropriate on-side
and cross-side information and
alert the crew when Category II
requirements or limits are not sat-
i s f i e d .
The Category II Annunciator is
functional in either single or dual
EFIS installations and provides
different limits for FAR and JAR-
AWO certifications. The function-
ality and requirements are slightly
different between the two sys-
tems, however, the intended
function is the same.
o
Software release 0702
expanded the configuration
options for Category II display.
The additional options allow the
operator to select at installation
time whether to display the CAT
II annunciation as well as the
excessive deviation limits or the
CAT II annunciation only. These
additional options provide the
flexibility of display where the
operator C ategory II limits
deviate from the set limit set in
the EFS 40/50 configuration
