9TAKEOFF TOURSelecting Com/Nav FrequenciesWhile the GNS 530W is acquiring a position,let’s take a minute to dial in the active and standbyfrequencies you’ll be using for the first phase of yourflight. The GNS 530W display is divided into separate‘windows’ (or screen areas), including a COM window,VLOC window (by default with VOR ident/radial, butselectable for other data — including a traffic display)and a GPS window which occupies the right 3/4 of thedisplay.COM Window:Active FrequencyCOM Window:Standby Frequency(with tuning cursor)VLOC Tuning Window andVLOC Ident Window(Ident Window is user-selectable)Pushing the small left knob moves the tuningcursor back-and-forth between the COM and VLOCfrequency windows. To select the active frequency, youmust first enter the frequency in the standby field, anduse the COM (or VLOC) flip-flop key to move it tothe active field.To change the standby communication (COM) orVLOC frequency:1. If the tuning cursor is not currently in thedesired window (COM or VLOC), press thesmall left knob momentarily to switch thehighlight between the COM and VLOC win-dows. Adjusting the frequencies with the largeand small left knobs will affect the standbyfrequency.2. Turn the large left knob to select the desiredmegahertz (MHz) value. For example, the“117” portion of the frequency “117.70”.3. Turn the small left knob to select the desiredkilohertz (kHz) value. For example, the “.70”portion of the frequency “117.70”.4. To activate the selected frequency, press theappropriate flip-flop key—COM for commu-nication frequencies or VLOC for VOR/Localizerfrequencies.Once you’ve entered the active frequency, simplyrepeat steps 1 through 3, above, to enter the standbyfrequency. After both communication frequencies havebeen entered, you may elect to keep the COM window‘hot’ by leaving the cursor on the standby frequency, ormove the cursor to the VLOC window by pressing thesmall left knob.NOTE: When selecting VLOC frequencies, thetuning cursor automatically returns to the COMwindow after 30 seconds of inactivity.Cursor highlights COM window.To switch the active and standby frequen-cies, press the COM flip-flop key. Switchingthe active and standby frequencies does notremove the cursor from the COM window.GNS 530W onlySelecting Com/Nav Frequencies
