8. As you cross the FAF, the destination sequences
to the MAP (“RW22”). With the needle cen-
tered, fly toward the MAP, observing the alti-
tude minimums dictated by the approach plate.
On-screen
CDI scaling continues to tighten to
350 feet, full-scale deflection.
9. As you approach the MAP, a waypoint alert
(“ARRIVE WPT”) appears in the lower right
corner.
10. As you cross the MAP, “SUSP” appears
above the OBS key, indicating that automatic
sequencing of approach waypoints is sus-
pended 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.
Course From Fix Flight Plan Legs
Certain approach, departure, and arrival procedures
in the Jeppesen database contain course from fix flight
plan legs. The 400W-series is able to load these legs
into the flight plan along with the rest of the procedure
data, and to provide navigation along these legs.
There are three different types of course from fix legs:
TYPE 1: Course from fix to distance, or Course
from fix to DME distance
Course from fix to distance legs will appear in the
flight plan like normal waypoints, but the destination

1. As you reach the initial approach fix (PMD), a
waypoint alert (“RT TO 070° x S”) will appear
in the lower right corner of the screen. As the
distance to the IAF approaches zero, the alert
is replaced by a turn advisory (“RT TO 070°
NOW”). Dial the outbound course into the
CDI (or HSI) using the OBS knob and initiate a
standard rate turn to this course heading.
2. Fly the outbound course, keeping the CDI
needle centered. You are now on the “course
from fix to distance” leg, as shown on the
