While viewing any NAV page, turn the small rightknob to select a different NAV page. The pilot may findthis selection process convenient to cycle between theDefault NAV Page and the Map Page, which are two ofthe most frequently used pages. Other pages are providedfor TAWS information (if configured for TAWS), to listfrequencies for the flight plan, and to display currentsatellite reception.Figure 2-3 NAV PagesDefault NAV Map TAWS or TERRAINNAV/COM Satellite StatusNOTE: *Six or Seven NAV pages are availablewhen the GPS 500 installation includesconnection to traffic and/or weather informationsources. See Section 12 of this manual for moreinformation.2.3 DEFAULT NAV PAGEThe first NAV page is the Default NAV Page (Figure2-4). The Default NAV Page displays a “look ahead” mapdisplay with your present position at the bottom center ofthe page. The top of the page displays desired track (DTK),ground track (TRK), and distance to destination waypoint(DIS). The bottom of the page indicates ground speed (GS),active to/from waypoints (only active to, for a direct-todestination) and estimated time enroute (ETE). A graphiccourse deviation indicator (CDI) also appears at the bottomof the page Unlike the angular limits used on a mechanicalCDI coupled to a VOR or ILS receiver, full scale limits forthis CDI are defined by a GPS-derived distance (0.3, 1.0, or5.0 nm), as indicated at both ends of the CDI. By default,the CDI scale automatically adjusts to the desired limitsbased upon the current phase of flight: oceanic, enroute,terminal area, or approach. The pilot may also manuallyselect the desired scale setting as outlined in Section 8.4.CourseDeviationIndicator(CDI)User-Selectable Data Fields (all four corners)Active Legof FlightPlan, orDirect-toDestinationFigure 2-4 Default NAV PageCurrent Page Group Number of Pages inCurrent Page GroupPosition of CurrentPage within CurrentPage GroupMapRange
