LS pb should be selected before approach briefing so pilot
can read ILS freq., and course off of PFD. This allows the pilot to
double-check the actual ILS being used as well as ensures that the LS pb is
selected before the approach begins. If wrong ILS freq. is showing make sure
that RADNAV ILS is cleared.
Note: if LS pb is not selected when approach is armed then
ILS will flash in amber on the PFD
DA - If the approach uses a DA then the barometric altimeter
is being used and no autocallout will be made for 100 above or minimums. Enter
DA information in MDA position on approach page in MCDU (PERF APPR).
DH or AH - If DH or AH is being used then radio altimeter is
being used and autocallouts are available for 100 above and minimums. Use the
DH line select key for entry of minimums information in MCDU (PERF APPR).
When cleared for approach press the APPR pb on FCU. Then
press to engage the second autopilot on FCU. Both autopilots should be engaged
for all ILS approaches. Note blue GS and LOC on FMA indicating glideslope and
localizer are armed for capture. Disconnect autopilot prior to 40 ft. below DA
for CAT I ILS.
