Course From Fix Flight Plan Legs
Certain approach, departure, and arrival procedures in the Jeppesen database contain
course from fi x fl ight plan legs. The GNS 430 is able to load these legs into the fl ight plan
along with the rest of the procedure data, and to provide navigation along these legs.
There are three different types of course from fi x legs:
TYPE 1: Course from fix to distance, or Course from fix to DME distance
Course from fi x to distance legs will appear in the fl ight plan like normal waypoints,
but the destination name will
always begin with a “D”, fol-
lowed by a distance in tenths
of nautical miles from the
waypoint fi x. This example
uses the VOR/DME RWY 25
approach into Palmdale, Cali-
fornia (KPMD) and includes a
teardrop course reversal.
1. As you reach the initial
approach fix (PMD), a waypoint alert (“NEXT DTK 070°”) 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 (“TURN TO
070°”). 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 FAF, a waypoint alert (“NEXT DTK 265°”) 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.
