c. Fly the procedure turn. After the procedure turn outbound, set the inbound course on
the HSI.
d. On the inbound intercept to the final course, fly to center the CDI.
e. Set the GPS SEQ switch to the AUTO position. The GNC 300 will resume automatic
waypoint sequencing for the remaining approach waypoints.
6. Once the aircraft is within 2 nm of the FAF (and the approach is armed), the ‘ACTV’ annun-
ciator will illuminate and the CDI scale will ramp down to 0.3 nm.
NOTE: If the ACTV annunciator does not illuminate, do not descend after crossing the FAF
and fly all published missed approach procedures.
7. Upon reaching the FAF, the GNC 300 will automatically sequence to the MAP waypoint.
To fly a missed approach procedure:
If an approach is terminated, the GNC 300 may be used to navigate to the missed approach
holding point using one of the following procedures.
NOTE: To comply with TSO specifications, the GNC 300 will not automatically sequence
to the missed approach holding point. The missed approach holding point will be displayed
as the next available waypoint, which the pilot may activate when authorized. You must
fly all published missed approach procedures before selecting the missed approach hold-
ing point on the GPS. If you want to disarm the approach and return the CDI scale to the
1 nm sensitivity, press the GPS APR switch.
If the approach procedure permits navigation direct from the MAP to the missed
approach holding point:
1. After the MAP has been crossed, press the
D
key. The GNC 300 will automatically
display the first waypoint of the missed approach as the next approach waypoint.
2. Press
E
to confirm the destination. The GNC 300 will provide a direct navigation
course to the waypoint.
