Garmin GNC 420W Pilots Guide - Page 13

SECTION 1 INTRODUCTION 1.3 Takeoff Tour Overview The Garmin GNC 420 provides the pilot accurate navigational data and communication capability, along with non-precision and precision approach certification in the IFR environment. The takeoff tour is designed to familiarize the pilot with: • Powering up the unit • Changing frequencies • Entering data • Performing a simple direct-to • Selecting IFR procedures • Using some limited flight plans In addition, this section briefly covers the Default NAV Page, the Map Page, and the NAV/COM Page, which are available as part of the NAV Page Group. These pages are used for most of the in-flight navigation. The takeoff tour assumes that the unit and antennas have been properly installed and that the GNC 420's default settings have not been changed. If any of the factory default settings (position format, units of measure, selectable fields, etc.) have been changed, the pictures shown here may not exactly match what is shown on the GNC 420. Prior to using the GNC 420 for the first time, Garmin recommends that the aircraft be moved to a location that is well away from buildings and other aircraft so the unit can collect satellite data without interruption. This takeoff tour is intended to provide a brief introduction of the GNC 420's major features. Sections 2 through 12 of this manual describe these features and others in additional detail. Refer to these sections, as needed to learn or review the details regarding a particular feature. After becoming familiar with the basics, some suggested reading within this Pilot's Guide includes: • Flight plan features - Section 5 • IFR procedures - Section 6 • Waypoint information pages (database information) - Section 7 • Unit settings (configuring the unit to the pilot's preferences) - Section 9 If more information is needed, Garmin's Customer Service staff is available during normal business hours (U.S. Central time zone) at the phone and fax numbers listed on page ii. Garmin can also be reached by mail (page ii) or at our website address, www.garmin.com. Powering up the GNC 420 The GNC 420's power and COM volume are controlled using the COM Power/Volume Knob at the top left corner of the unit. Turning it clockwise turns unit power on and increases the COM radio volume. After turning the unit on, a welcome page appears briefly while the unit performs a self test, followed sequentially by the Unit Type Page (Figure 1-4) and the Software Version Page. Then (depending on configuration) the Weather Page, the Traffic Page, the Aviation Data Page, the Land/Terrain/ Obstacles Database Page, and the Situational Awareness Page are sequentially displayed.
