The map panning feature is enabled by pushing the Joystick. The map range is adjusted by turning the
Joystick. If the map range is adjusted while panning is enabled, the map is re-centered on the Map Pointer.
NEXRAD
NOTE: NEXRAD cannot be displayed simultaneously with terrain, echo tops, turbulence, or airborne weather
radar data on the same map.
The National Weather Service (NWS) operates the WSR-88D, or NEXRAD (NEXt-generation RADar)
system, an extensive network of 156 high-resolution Doppler radar systems. The NEXRAD network provides
centralized meteorological information for the continental United States and selected overseas locations. The
maximum range of a single NEXRAD site is 250 nm.
Individual NEXRAD sites supply the network with radar images, and the images from each radar site may
arrive at the network at different rates and times. Periodically, the weather data provider compiles the available
individual site images from the network to form a composite image, and assigns a single time to indicate when
it created the image. This image becomes the NEXRAD weather product. Individual images--gathered from
each NEXRAD site--differ in age, and are always older than the displayed NEXRAD weather product age. The
data provider then sends the NEXRAD data to the SiriusXM Weather service, whose satellites transmit this
information during the next designated refresh time for the NEXRAD weather product.
Because of the time required to detect, assemble, and distribute the NEXRAD weather product, the displayed
weather information contained within the product may be older than the current radar synopsis and may not
depict the current weather conditions. The NEXRAD weather product should never be used as a basis for
maneuvering in, near, or around areas of hazardous weather regardless of the information it contains.
The system displays either base or composite NEXRAD imagery, depending on the model of data link
receiver installed.
