Prior to the FAF
Prior to the FAF, baro-VNAV can be manually
selected to recover vertical guidance after the
LPV VNAV has failed. VNAV will then be avail-
able to continue to LNAV/VNAV minimums or
LNAV minimums, as appropriate. This is accom-
plished on the Active Arrival Data page by press-
ing DEP/ARR and choosing ARR DATA (Figure
16A-13). Pressing the APPR VNAV GP will se-
lect between GPS altitude VNAV (LPV) and
baro-VNAV (BARO).
Once BARO is selected the change in VNAV
must be executed. VNAV will return and the
approach can continue to LNAV/VNAV mini-
mums or LNAV minimums. It is critical to un-
derstand that LPV minimums are not to be flown
during this operation.
PFD annunciations will display “TERM” and
“GPS APPR” instead of “LPV TERM” and
“LPV APPR” (Figure 16A-14) Additionally,
“LPV NOT AVAILABLE” and “USE LNAV
MINIMUM” messages will be removed from
the displays and the CDU message page.
After the FAF
If SBAS guidance fails after the FAF, the descent
may be continued to the LNAV minimum or a
missed approach can be flown. If a descent is
continued it can only be done using VS, FLC,
or PTCH mode since baro-VNAV is not selec-
table at this point and VNAV deviation will be
flagged inoperative.
MISSED APPROACH
Pressing the go-around button will allow the
FMS to sequence to missed approach fixes after
reaching the missed approach point. Lateral
guidance will remain in approach mode while
on f inal and then sequence to terminal mode,
as appropriate, when past the missed approach
point. PFD annunciations will change to
“TERM” to indicate when the CDI scale has
changed.
