SECTION 6 PROCEDURES 3) Fly the outbound course. The Map Page depicts the flight path extending indefinitely from PMD VOR (Figure 6-67). The distance (DIS) on the Default NAV Page, the Map Page, and the Active Flight Plan Page increases, indicating the distance back to PMD VOR. Figure 6-67 Map Page 4) Upon reaching the desired altitude (5000'), press the OBS Key to return to automatic leg sequencing. Confirm that 'SUSP' no longer appears directly above the OBS Key. 5) An alert ('NEXT DTK 126°') appears, providing guidance to the inbound course (Figure 6-68) The actual desired track (DTK) depends on the ground speed and distance from PMD VOR. Intercept and fly the inbound course. 6) When approaching PMD VOR (the missed approach holding point), an alert message in the lower right-hand corner of the screen recommends the holding pattern entry procedure ('HOLD PARALLEL'). When flying the holding pattern, a timer appears on the Default NAV Page. The timer automatically resets on each outbound and inbound portion of the holding pattern. 7) Note that the GNC 420 again displays 'SUSP' above the OBS Key. Automatic waypoint sequencing is suspended at the missed approach holding point. A waypoint alert ('APPRCHING WPT') appears in the lower right corner of the screen each time the aircraft approaches PMD VOR in the holding pattern. 8) When leaving the holding pattern, press the PROC Key to reactivate the approach, or select a different approach, or press the Direct-to Key to select another destination.
