MAP DATUMS

When should I use the OBS key to return to auto sequencing, and what happens when I do?

The most common application for using the OBS Key is the missed approach. The GNS 530 suspends automatic waypoint sequencing (indicated by a ‘SUSP’ annunciation directly above the OBS Key; see Figure C-4) when the aircraft crosses the missed approach point (MAP). This prevents the GNS 530 from automatically sequencing to the missed approach holding point (MAHP). If a missed approach is required, press the OBS Key to return to automatic waypoint sequencing and sequence the approach to the MAHP. See Section 6.2, Flying the Missed Approach for more information on missed approaches.

How do I skip a waypoint in an approach, departure or arrival?

The GNS 530 allows the pilot to manually select any approach, departure, or arrival leg as the active leg of the flight plan. This procedure is performed from the Active Flight Plan Page by highlighting the desired waypoint and pressing the Direct-toKey twice, then press the ENT Key to approve the selection (Figure C-5). The GPS then provides navigation along the selected flight plan leg, so be sure to have clearance to that position. See Section 5.2, Shortcuts for more information.

Why won’t my unit automatically sequence to the next waypoint?

The GNS 530 only sequences flight plan waypoints when automatic sequencing is enabled (i.e., no ‘OBS’ or ‘SUSP’ annunciation directly above the OBS Key). For automatic sequencing to occur, the aircraft must also cross the ‘bisector’ of the turn being navigated. The bisector is a perpendicular line between two flight plan legs which crosses through the waypoint common to both legs.

How do I fly the GPS with an autopilot and DG heading bug?

If the installation does not have an HSI, the pilot should make the course selections on the external CDI’s OBS knob and the DG heading bug.
