• NEXRAD base reflectivity is sampled at the minimum antenna elevation angle. An individual NEXRAD
site cannot depict high altitude storms at close ranges. It has no information about storms directly over the
radar site.
• When zoomed in a square block on the display represents an area of 2 ½ miles. The intensity level
reflected by each square represents the highest level of NEXRAD data sampled within the area.
METARS
Airports with METAR data are displayed with a colored flag next to the airport symbol on the map.
If an airport has METAR data a weather
page will be added to the airport info after
the frequency page, usually page 2.
TAF's
Airports with TAF's will have a special "T" symbol next to the airport on the map page. In additional, there will
be a TAF button on the airports info page. TAF's are given in their original coding.
TFR’s
Active TFR’s are drawn in RED and future TFR’s are YELLOW. Your screen will remember the last TFR's
displayed upon shut-down so those that remain active are displayed at the next power-up (before XM WX
comes online). This is done by saving all TFR's onto the SD Card as a file named "TFR.xml". If a TFR
becomes inactive before the next power-cycle, that TFR will not be displayed. Similarly, if a future TFR
becomes active before the next power-cycle, that TFR will be displayed.
Lightning
Lightning is displayed as lightning bolts as part of the NEXRAD weather display.
To enable/disable Lightning press [MAP] -> [WX] -> [LGHT ON/OFF]
Winds Aloft
Winds aloft are displayed over the map page using standard NOAA barbed symbols. To change
the altitude, use the right knob to select WNDS as the function. Altitudes are given in Flight Levels
(i.e. FL120 is 12,000ft)
To enable/disable Winds Aloft press [MAP] -> [WX] -> [WNDS ON/OFF]
XM Weather
Weather Module installation
The WeatherWorks XM Weather Module should be mounted on the inside of the aircraft and the antenna
located on the aircraft glare shield. The XM Weather module should be powered from a 12V aircraft source.
The weather receiver communicates with the EFIS screens using the Ethernet port. For a dual screen
