Reported/forecast products use a date/time stamp. On what are the date and time based? Date and time are based on Zulu time as reported by appropriate weather stations, not on when the data is received by the data link sensor. 5. When and how is weather data information received?. Before the GDL 69/69A can be used, the XM Satellite Radio subscription must be activated. XM Satellite Radio offers several subscriptions at different service levels. Refer to the XM Satellite Radio website for information regarding subscription options. 6. What type of lightning strike information does XM Weather provide? Only cloud-to-ground lightning is provided by XM. To receive cloud-to-cloud lightning strike information, the aircraft must be equipped with additional lightning detection equipment, such as Stormscope. 7. What is NEXRAD? NEXRAD (NEXt generation RADar) is a Doppler radar system that has greatly improved the detection of meteorological events such as thunderstorms, tornadoes, and hurricanes. 8. What are the coverage areas of the XM Satellite signal? At what altitude must the aircraft fly to receive the XM signal? The XM signal provides full coverage of the continental United States. The information can be received on the ground and while flying at any altitude throughout North America. 9. A pilot is planning a cross-county flight. Does weather data provided by WxWorx satisfy FAR 91.103 prefight action? No, weather data received in the cockpit is not approved to satisfy FAR 91.103. One must receive approved weather data from the National Weather Service/FSS. Use data link weather as a supporting reference only. XM Weather is not to be used as a main source for making decisions before or during flight. 10. A pilot is on a VFR flight from KXYZ to KABC.
