10) After crossing the FAF, the destination
sequences to the MAP (‘RW22’, the runway
threshold). With the needle centered, fly
toward the MAP, observing the altitude
minimums dictated by the approach plate.
When viewing the Map Page, note that the final
course segment is displayed in magenta (the
active leg of the flight plan always appears in
magenta) and a dashed line extends the course
beyond the MAP (Figure 6-47).

11) When approaching the MAP, a waypoint alert
(‘APPRCHING WPT’) appears in the lower right
corner.
12) After crossing the MAP, ‘SUSP’ appears above
the
OBS
Key (Figure 6-48), indicating that
automatic sequencing of approach waypoints
is suspended at the MAP. A ‘from’ indication
is displayed on the CDI and Default NAV Page,
but course guidance along the final approach
course continues. Do
not follow this extended
course. Follow published missed approach
procedures using the
OBS
Key to initiate the
missed approach sequence, as outlined in
‘Flying the Missed Approach’ in this section.

Vectors to Final
Take a second look at the ‘VOR 22’ approach into
Billard Municipal. Instead of following the DME arc, ATC
tells the pilot to expect vectors onto the final approach
course. There are several ways to select ‘vectors to final’
with the GNC 420. The first two options below normally
require the least workload to accomplish:
• When the approach is first selected, choose
‘VECTORS’ from the Transitions Window.
• Load a full approach (including the IAF from the
Transitions Window) as described in Section 6.1.
When cleared, press the
PROC Key and select
‘Activate Vectors-To-Final?’.
• Load the full approach as described in Section
6.1. Use the Direct-to Key (by pressing it twice)
from the Active Flight Plan Page to select the
desired leg of the approach.
