MAP DATUMS

What happens when I select an approach? Can I store a flight plan with an approach, departure, or arrival?

When loading an approach, departure, or arrival into the active flight plan, a set of approach, departure, or arrival waypoints is inserted into the flight plan—along with a header line describing the selected instrument procedure (Figure C-2). The original enroute portion of the flight plan remains active, unless the pilot ‘activates’ the instrument procedure; which may be done when the procedure is loaded or at a later time.

Figure C-2 Active Flight Plan Page

Flight plans can also be stored with an approach, departure, or arrival. Keep in mind that the active flight plan is erased when the unit is turned off and overwritten when another flight plan is activated. When storing flight plans with an approach, departure, or arrival, the GNS 530 uses the waypoint information from the current database to define the waypoints. If the database is changed or updated, the GNS 530 automatically updates the information if the procedure has not been modified. If an approach, departure or arrival procedure is no longer available, the flight plan becomes locked until the procedure is deleted from the flight plan or the correct database is installed. For information on loading an approach, departure, or arrival, see Section 6.1. See Section 5.1 for instructions on saving and copying flight plans.

Can I file slant Golf (‘/G’) using my GPS?

Yes, the pilot may file a flight plan as /G if the GNS 530 is a certified A1 or A2 installation. If flying enroute, the pilot may file /G with an expired database only after having verified all route waypoints. Non-precision approaches may not be flown with an expired database. See an approved Airplane Flight Manual Supplement for more information.

What does the OBS key do and when do I use it?

The OBS Key is used to select manual (OBS mode) or automatic sequencing of waypoints. Activating OBS mode (as indicated by an OBS annunciation directly above the OBS Key) holds the current ‘active to’ waypoint as the navigation reference and prevents the GPS from sequencing to the next waypoint. When OBS mode is cancelled, automatic waypoint sequencing is selected, and the GNS 530 automatically selects the next waypoint in the flight plan once the aircraft has crossed the present active-to waypoint.
