CAT II OPERATION
The information contained herein supplements the information of the
the basic AOM Normal Procedures.
AUTOPILOT COUPLED CAT II APPROACH
BEFORE INTERCEPTING LOCALIZER COURSE
− Perform the Descent/Approach/Before Landing checklists, as
appropriate.
− Perform the Radio Altimeter test.
− Set the CAT II Decision Height on both Display Control Panels.
− Check radio altimeter information on both PFD.
− Select the same ILS frequency on both RMU.
NOTE: - After test, if Radio Altimeter is checked not functioning
properly the CAT ll approach must discontinued.
- A minimum distance of 4 NM to the Outer Marker is
recommended for interception and stabilization along the
approach course.
BEFORE INTERCEPTING THE GLIDE SLOPE
− Monitor radio altimeter information.
− Lower landing gear (one dot below GS interception) and set
flaps to 22°.
− Set the Approach Speed (V
APP
) for flaps 22° on AP bug (green
bug).
NOTE: The V
APP
is determined by adjusting the V
APP
for head wind
component and gust according to the following equation:
V
APP
= V
REF
+ WIND CORRECTION, where:
WIND CORRECTION = ½ head wind component + full gust,
limited to 20 kt.
− Stabilize and maintain the Approach Speed (V
APP
) for flaps 22°.
− Set approach climb speed on SPD reference speed bug (cyan
bug).
− Be sure that Marker Beacon audio is on.
