Course From Fix Flight Plan Legs
Certain approach, departure, and arrival procedures
in the Jeppesen database contain Course From Fix flight
plan legs. The 500W-series unit is able to load these
legs into the flight plan along with the rest of the proce-
dure 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 appears in the flight
plan like normal waypoints, but the destination name
alwaysbeginswitha"D",followedbyadistancein
tenths of nautical miles from the waypoint fix. This

1. As you reach the initial approach fix (PMD),
a waypoint alert (“Right to 072° in x sec”)
appears in the lower right corner of the screen.
As the distance to the IAF approaches zero, the
alert is replaced by a turn advisory (“Right to
072° now”). Dial the outbound course into the
CDI (or HSI) using the OBS knob and initiate a
standard rate turn to this course heading.
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.
