Refer to Figure 6-41 for the following steps.
3) Within 30 nm of KTOP, the GNC 420 switches
from enroute mode to terminal mode and the
CDI scale transitions from 5.0 to 1.0 nm, full
scale deflection.
4) If the approach has not yet been activated (in
step 2), do so when cleared for the approach
(Figure 6-42).

5) When approaching the IAF (D258G), a waypoint
alert (‘NEXT DTK 353°’) appears in the lower
right corner of the screen (Figure 6-43). As the
distance (DIS) to the IAF approaches zero, the
alert is replaced by a turn advisory (‘TURN TO
353°’).

6) Follow the arc, when the course select setting
and desired track differ by more than 10°, a
‘Set course to ###°’ message appears on the
