Using Xm Wx Satellite Weather Products - Garmin G1000 Pilot's Manual

USING XM WX SATELLITE WEATHER PRODUCTS

The Weather Data Link Page is in the Map group of pages. It is the primary starting point for viewing weather
data because it can display all available XM weather products. No other G1000 page can display all XM weather
products.
When a weather product is active on the Weather Data Link Page or the Navigation Map Page, the age of the
data displays on the screen. This represents the age of the product, based on the difference between when the
data was assembled on the ground and the current GPS time (Figure 6-2).
Weather products are refreshed at specific intervals as defined in the Refresh Rate column in Table 6-1.
The refresh rate represents the interval at which XM Satellite Radio broadcasts new signals that may or may not
contain new weather data. It does not represent the rate at which weather data is updated or new content is
received by the Data Link Receiver. Weather data and new content are updated at intervals that are defined and
controlled by XM Satellite Radio and its data vendors.
If, for any reason, a weather product is not refreshed within 30-, 60-, or 90-minute intervals as defined in
the Expiration Time column in Table 6-1, 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, the color and time displayed in the upper right
corner of the Weather Data Link Page changes from light blue to yellow.
