2) Fly the ‘course from fix to distance’ leg, as
shown on the Active Flight Plan Page and the
Default NAV Page. Note the magenta line in
Figure 6-51, 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 automatically
sequences to the next leg upon reaching
‘D13.0’.
3) At 13.0 nm from the FAF, a waypoint alert
(‘NEXT DTK 265°’) appears along the bottom
of the screen (Figure 6-51). Turn to intercept
the final approach course and watch for the
CDI needle to begin to center.

4) When approaching the intermediate fix (CF25),
a waypoint alert (‘NEXT DTK 265°’) appears.
5) Within 2.0 nm of the FAF (THERO), the GNS
530 switches from terminal mode to approach
mode. (‘APR’ appears in the lower left corner
of the screen—replacing ‘TERM’.) CDI scaling
is tightened from 1.0 to 0.3 nm, full scale
deflection.
6) When approaching the FAF, ‘NEXT DTK 265°’
appears along the bottom of the screen.
7) After crossing the FAF, the destination
sequences to the MAP (MA25).
8) When approaching the MAP, a waypoint alert
(‘APPRCHING WPT’) appears along the bottom
of the screen.
9) After crossing the MAP, ‘SUSP’ appears above
the OBS Key (Figure 6-52), indicating that
automatic sequencing of approach waypoints
is suspended at the MAP. If a missed approach
is required, use the OBS Key to initiate the
missed approach sequence, as outlined
below.
