4. 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 datalink receiver.
5. When and how is weather data information received?
Before the GDL 69/69A can be used, an 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 be
to receive the XM signal?
The XM signal provides full coverage over the continental United States.
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 preflight 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 datalink
weather as a supporting reference only. XM Weather is not to be used as a main source
for making decisions before or during flight.
