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
active flight plan and default NAV pages.
Note the magenta line in the bottom figure,
which represents the currently active leg of
the approach. The distance (DIS) displayed on
the above screens is TO the “D13.0” point. The
flight plan will automatically sequence to the
next leg upon reaching “D13.0”.
3. At 13.0 NM from the IAF, a waypoint alert
(“DTK 265° x S”) will appear in the lower right
corner of the screen. Make a standard rate turn
to the right to intercept the final approach
course and watch for the CDI needle to begin
to center.
4. As you approach the intermediate fix (CF25),
a waypoint alert (“DTK 265° x S”) will appear.
Make any necessary course adjustments.
5. Approach is active when the FAF is the TO
waypoint and bearing and track are within
45° of the final approach course. The 400W-
series unit will switch from terminal mode to
approach mode. (“LNAV” will appear in the
lower left corner of the screen—replacing
“TERM”.) CDI scaling will be tightened from
1.0 to 0.3 nautical mile full scale deflection,
or 2° full scale deflection, whichever is less at
the FAF, and as defined for the approach. The
change occurs over 2 NM and is completed by
the FAF.
6. As you approach the FAF, “DTK 265° x S”
will appear in the lower right corner of the
screen.
7. As you cross the FAF, the destination sequences
to the MAP (MA25). With the CDI needle
centered, fly toward the MAP, observing the
altitude minimums dictated by the approach
