15) After crossing the MAP, ‘SUSP’ appears above
the
OBS
Key (Figure 6-88), indicating that
automatic sequencing of approach waypoints
is suspended at the MAP. A ‘FROM’ indication
is displayed on the CDI and Default NAV Page,
but course guidance along the final approach
course continues. Do not follow this extended
course. Follow published missed approach
procedures, using the
OBS
Key to initiate the
missed approach sequence.
Figure 6-88 ‘SUSP’ Annunciation
NOTE: In addition to using the
OBS
Key to
initiate the missed approach sequence, the
CDI
Key may be used to manually switch the
external CDI output to the GPS receiver. ‘GPS’ is
indicated above the
CDI
Key. If the pilot leaves
the CDI output on ‘VLOC’ and the pilot is using
an external CDI (not an HSI), expect reverse
sensing on the backcourse of the ILS.
6.4 POINTS TO REMEMBER FOR ALL
APPROACHES
• The GNS 430 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 GNS
430 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).
