The takeoff tour is designed tofamiliarize the pilot with the operation of the GNS 430by :• Powering up the unit• Changing frequencies• Entering data• Performing a simple direct-to• Selecting IFR procedures• Using some limited flight plansIn addition, this section briefly covers the Default NAVPage, the Map Page, and the NAV/COM Page, which areavailable as part of the NAV Page Group. These pages areused for most of the in-flight navigation.The takeoff tour assumes that the unit and antennashave been properly installed and that the GNS 430’sdefault settings have not been changed. If any of thefactory default settings (position format, units of measure,selectable fields, etc.) have been changed, the picturesshown here may not exactly match what is shown onthe GNS 430.
