14) When approaching the MAP, a waypoint alert
(‘APPRCHING WPT’) appears in the lower right
corner (Figure 6-72).
Figure 6-72 Waypoint Alert
15) After crossing the MAP, ‘SUSP’ appears above
the OBS Key (Figure 6-73), 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.

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.
