Procedure Turn Approach
7. After approximately one minute, make a 180°
right turn to a heading of 340° to intercept
the inbound course. The unit will sequence to
the inbound leg to the FAF, the CDI needle will
swing to the opposite side to provide proper
sensing along the final course segment and
“DTK 025° NOW” will appear in the lower
right corner of the screen.
8. As the CDI needle starts to center, make a right
turn to 025°—the final approach course.
9. When within 45° of the final approach course
and the FAF is the TO waypoint, the 400W-series
unit switches from terminal mode to
“approach” mode. CDI scaling is tightened from
1.0 NM full scale deflection to either 0.3 NM
or 2° full scale deflection whichever is less at
the FAF. The change occurs over 2 NM and is
completed by the FAF.
10. As you approach the FAF, a waypoint alert in
the lower right corner (“NEXT DTK 025°”)
will appear. Make any course adjustments
necessary for the final course segment (FAF to
MAP).
11. As you cross the FAF, the destination sequences
to the MAP (“RW03”, the runway threshold).
With the needle centered, fly toward the MAP,
observing the altitude minimums dictated by
the approach plate.

DO NOT USE FOR
NAVIGATION
NOTE: 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. The
dashed line is provided for situational awareness only
and should NOT be used for navigation. Follow the
published missed approach procedures.
12. As you approach the MAP, a waypoint alert
(“ARRIVING WPT”) will appear in the lower
right corner.
13. As you cross the MAP, “SUSP” will appear
above the OBS key, indicating that automatic
sequencing of approach waypoints will be sus-
