PROCEDURES

Flying the ILS Approach

When ‘Activate?’ is selected for an ILS approach, automatic switching of the external CDI is enabled (unless turned off from the CDI/Alarms Page). Once established on the inbound course to the FAF, the external CDI guidance automatically switches from ‘GPS’ (shown in green text) to ‘VLOC’ (shown in white text). If the pilot has forgotten to activate the ILS frequency (step 4 below), automatic selection of ‘VLOC’ does not occur (refer to Figure 6-65 for the following steps).

DO NOT USE FOR

NAVIGATION

1)Within 30 nm of KFLG, 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.

2)If the approach has not yet been activated, (in steps on the preceding page), do so when cleared for the approach.

3)When approaching the IAF (SHUTR), a waypoint alert (‘NEXT DTK 030°’) appears along the bottom of the screen (Figure 6-66).

4)Press the VLOC Flip-flopKey to activate the ILS frequency. If this step is forgotten, the GNS 530 displays a reminder message (within 3 nm of the FAF) to activate the ILS frequency.

5)As the distance (DIS) to the IAF approaches zero, the alert is replaced by a turn advisory (‘TURN TO 030°’).

6)Fly the outbound course.

7)Approximately one minute past SHUTR intersection, the alert message ‘START PROC TRN’ (Figure 6-67) appears along the bottom of the screen (if the pilot has not yet begun the procedure turn).
