As the distance to the IAF approaches zero,
the waypoint alert is replaced by a turn
advisory (“Right to 072° in x sec”). 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 automatically sequences to the next
leg upon reaching “D13.0”.
3. At 13.0 NM from the IAF, a waypoint alert
(“Next DTK 265° in x sec”) appears in the
lower right corner of the screen. Make a stan-
dard rate turn to the right to intercept the final
approach course and watch for the CDI needle
to begin to center.
At 13.0 NM from the IAF, a waypoint alert
appears (“Next DTK 265° in x sec”). Make a
standard rate turn to intercept the approach
course.
4. As you approach the intermediate fix (CF25),
a waypoint alert (“Next DTK 265° in x sec”)
appears. Make any necessary course adjust-
ments.
5. When within 45° of the final approach course
(past CF25), the 500W-series unit switches
from terminal mode to approach mode.
(“LNAV” appears in the lower left corner of
the screen — replacing “TERM”.) CDI scaling
will be tightened from 1.0 to 0.3 NM full scale
deflection, or 2° full scale deflection, which-
ever 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, “Next DTK 265° in
x sec” appears 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
plate.
8. As you approach the MAP, a waypoint alert
(“Arriving at waypoint”) appears in the lower
right corner of the screen. CDI scaling continues
