Course From Fix Flight Plan Legs
Certain approach, departure, and arrival procedures in
the Jeppesen database contain course from fix flight plan
legs. The GNC 420 is able to load these legs into the
flight plan along with the rest of the procedure data, and
provide navigation along these legs.
There are three different types of course from fix legs:
• Course from fix to distance, or Course from fix to
DME distance
• Course from fix to altitude
• Course from fix to manual sequence
Course from fix to distance legs appear in the flight
plan like normal waypoints, but the destination name
always begins with a ‘D’, followed by a distance in nm
from the waypoint fix (Figure 6-60).

Figure 6-61 KPMD Approach
This example uses the VOR/DME RWY 25 approach into
Palmdale, California (KPMD) and includes a teardrop course
reversal (refer to Figure 6-61 for the following steps).
1) At the initial approach fix (PMD), a waypoint
alert (‘NEXT DTK 070°’) 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 (‘TURN TO 070°’). Dial the
outbound course into the CDI (or HSI) using
the OBS knob.
2) Fly the ‘course from fix to distance’ leg, as
shown on the Active Flight Plan Page and the
Default NAV Page (Figures 6-62 and 6-63).
Note the magenta line in Figure 6-63, which
represents the currently active leg of the
approach. The distance (DIS) displayed is TO
the ‘D13.0’ point. The flight plan automatically
sequences to the next leg upon reaching
‘D13.0’.
