4TAKEOFF TOUR The Garmin GNS 530 offers you accurate navigational data and communication capability, along withnon-precision and precision approach certification in the IFR environment. The Takeoff Tour is designedto familiarize you with the basic operation of the GNS 530 — including powering up the unit, changingfrequencies, entering data, performing a simple direct-to, selecting IFR procedures and provides a limitedintroduction to using flight plans. In addition, this section briefly covers the default navigation, map andfrequency pages available as part of the NAV page group. These pages are used for most of your in-flightnavigation.The Takeoff Tour assumes that the unit and antennas have been properly installed and you have notchanged any of the GNS 530’s default settings. If you have changed any of the factory default settings (po-sition format, units of measure, selectable fields, etc.), the pictures shown here may not exactly match whatyou see on your GNS 530. Prior to using your GNS 530 for the first time, we recommend that you taxi to alocation that is well away from buildings and other aircraft so the unit can collect satellite data without inter-ruption.Powering up the GNS 530The GNS 530’s power and COM volume are controlled using the COM power/volume knob at the topleft corner of the unit.
