3) Fly the outbound course. Once cleared to
sequence to the next leg, press the OBS Key.
Confirm that ‘SUSP’ no longer appears directly
above the OBS Key. An alert (‘NEXT DTK
186°’) appears in the lower right corner of the
screen (Figure 6-72) to provide guidance to the
next waypoint (HFD VOR). The actual desired
track (DTK) depends on the ground speed and
distance from HFD VOR.

4) Once the OBS Key is pressed, the GNC 420
automatically sequences to each waypoint
along the remainder of the departure route,
including the selected transition.
6.3 POINTS TO REMEMBER FOR ALL
APPROACHES
• The GNC 420 is designed to complement printed
approach plates and vastly improve situational
awareness throughout the approach. However,
the pilot must always fly an approach as it appears
on the approach plate.
• The active leg (or the portion of the approach
currently in use) is depicted in magenta on the
Map Page. When flying the approach, the GNC
420 automatically sequences through each leg
of the approach unless ‘SUSP’ appears above
the OBS Key. ‘SUSP’ indicates that automatic
sequencing of approach waypoints is suspended
on the current leg and normally appears at
holding patterns and upon crossing the missed
approach point (MAP).
