Foreword Sec 1 System Sec 2 PFD Sec 3 MFD Sec 4 Hazard Avoidance Features 4.7 XM Weather (Optional) The primary map for viewing XM Weather data are the Weather Data Link Pages in the Map Page Group. These are the only GDU 620 map displays capable of all available XM weather products. The Wx Weather pages may be oriented to either Track Up or North Up. 4.7.1 Using XM Satellite Weather Products When a weather product is active on the Weather Data Link Page or the Navigation Map Page, the age of the data is displayed on the screen. The age of the product is based on the time difference between when the data was assembled on the ground and the current GPS time. Weather products are refreshed at specific intervals (defined in the Refresh Rate column). If for any reason, a weather product is not refreshed within the 30, 60, 90, or 120 minute Expiration Time intervals, the data is considered expired and is removed from the display. This ensures that the displayed data is consistent with what is currently being broadcast by XM Satellite Radio services. If more than half of the expiration time has elapsed from the time the data is received, the color of the product age displayed changes to yellow. 4.7.2 Customizing the XM Weather Map Each Wx Data Link Map page may be customized individually. The Wx Data Link Map pages are customized by selecting options from the Page Menu. The Page Menu options include choices for Weather Setup and displaying the Weather Legends. The Weather Setup choice covers selections for adjusting the viewing ranges of the weather products. 1) While viewing a WX Data Link Map page of the WX page group, press the MENU key to display the Page Menu Options.
