In the GNS 530W, the left 1/4 of the display pro-vides a COM window (top two lines), a VLOC window, a select-able window (by default with VOR ident/radial, but selectablefor other data), and a three line annunciator window. The right3/4 of the display consists of a GPS window, which is whereyou’ll find the various navigation, waypoint information andsettings “pages”. The three lines in the bottom left window ofthe display are used for terrain, flight phase, and GPS integrityannunciators.COM WindowVLOC WindowGPSWindowVLOC Ident Window(user-selectable; can alsodisplay traffic or other data)Active Frequency on top & Standbyon bottom (highlighted by cursor)Terrain AnnunciatorFlight Phase AnnunciatorGPS Integrity AnnunciatorEach unique screen of information is referred to as a “page.”Pages are typically selected using the small and large rightknobs—with the cursor removed from the GPS window.CursorsThere are two separate cursors: a tuning cursor and a GPSwindow cursor. The tuning cursor is used to select the standbyCOM or VLOC frequency. Pushing the small left knob movesthe tuning cursor back-and-forth between the COM and VLOCfrequency windows. To set a new active frequency, you mustfirst enter the frequency in the standby field, then use the COMor VLOC flip-flop key to activate the new frequency. Push inon the small right knob and then turn the large right knob tomove the GPS window cursor around the page.Frequency Selection (530W only)1. If the tuning cursor is not currently inthe desired window (COM or VLOC),press the small left knob momentarilyto switch the highlight between theCOM and VLOC windows. Adjustingthe frequencies with the large andsmall left knobs will affect the standbyfrequency.2. Turn the large left knob to select thedesired megahertz (MHz) value. Forexample, the “117” portion of the fre-quency “117.70”.3. Turn the small left knob to select thedesired kilohertz (kHz) value. For exam-ple, the “.70” portion of the frequency“117.70”.4. To activate the selected frequency, pressthe appropriate flip-flop key—COM for communicationfrequencies or VLOC for VOR/Localizer frequencies.To Quickly Tune and Activate the 121.500 Emer-gency Channel1. In the GNS 530W, press and hold the COM flip-flop key for approximately two seconds.Data EntryData is entered in theGPS window using thesmall and large rightknobs.
