SECTION 6
PROCEDURES
6-15
Refer to Figure 6-35 for the following steps.
3) Within 30 nm of KTOP, the GNS 530 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 above), do so when cleared for the
approach (Figure 6-36).

5) When approaching the IAF (D258G), a waypoint
alert (‘NEXT DTK 353°’) appears along the
bottom of the screen. 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
Message Page (Figure 6-37).

7) The next point in the approach is an intermediate
fix, labeled ‘D025G’. When approaching this
intermediate fix, a waypoint alert (‘NEXT DTK
205°’) appears along the bottom of the screen.
As the distance to this fix approaches zero, the
alert is replaced by a turn advisory (‘TURN TO
205°’). Dial this course into the CDI (or HSI)
using the OBS knob.
8) At 2.0 nm from the FAF (TOP VOR), the GNS
530 switches from terminal mode to approach
mode. CDI scaling is tightened from 1.0 to 0.3
nm, full scale deflection.
