XM WX Weather Features XM WX Weather Features Displaying Weather Information The GXM 40 receives XM WX Weather data and shows it on the Map and Weather pages of the Garmin unit. The weather data for each feature comes from reputable weather data centers such as the National Weather Service and the Hydrometerological Prediction Center. (See the XM WX Satellite Weather Web site at http://weather.xmradio .com/weather for more information.
XM WX Weather Features METAR A METAR or METeorological Aeronautical Report is an international code used for reporting weather observations. If METAR data is available for an airport, a color-coded flag is shown next to the airport. To view the METAR data, select the flag with the map pointer. VFR (ceiling greater than 3000 ft. AGL and visibility greater than five miles) Marginal VFR (ceiling 1000–3000 ft. AGL and/or visibility three to five miles) IFR (ceiling 500 to below 1000 ft.
XM WX Weather Features AIRMET An AIRMET or AIRman’s METeorological Information can potentially affect all aircraft. This data can be especially helpful for pilots of light aircraft that have limited flight capability or instrumentation. An AIRMET must affect or be forecast to affect an area of at least 3,000 square miles at any one time.
XM WX Weather Features SIGMET A SIGMET (SIGnificant METeorological Forecast) advises of weather that is potentially hazardous to all aircraft. In the contiguous United States, the following items are covered: severe icing, severe or extreme turbulence, volcanic ash, dust storms, and sandstorms that lower visibility to less than three statute miles.
XM WX Weather Features TFR A Temporary Flight Restriction (TFR) temporarily restricts all aircraft from entering the selected airspace unless a waiver has been issued. TFRs are routinely issued for occurrences such as sporting events, dignitary visits, military depots and forest fires. TFRs are represented as an area highlighted by red (active) or yellow (not yet active). To view information about the TFR, select it with the map pointer.
XM WX Weather Features TAF Terminal Aerodrome Forecasts are issued by the National Weather Service for pilots. They include 24-hour forecasts on wind, visibility, expected weather conditions, and wind shear.
XM WX Weather Features Winds Winds Aloft Aviation units display winds using wind barbs or a wind streamline depending on the zoom range of the map. Similar to marine and automotive units, the wind barbs indicate wind speed and direction. Arrows indicate the direction of the wind streamline.
XM WX Weather Features Surface Winds Marine and automotive units show surface winds. The barb attached to the circle points in the direction of the wind. Wind speed is indicated by different flags attached to the barb.
XM WX Weather Features NEXRAD Radar NEXRAD or NEXt Generation Weather RADar displays precipitation, from very light rain and snow to strong thunderstorms, in varying shades and colors. The time stamp in the lower-left corner of the screen displays the elapsed time since the National Weather Service provided the information being displayed. NEXRAD can be displayed independently or with a variety of other weather information.
XM WX Weather Features Satellite Mosaic The Satellite Mosaic feature displays infrared composite images of cloud cover taken by geostationary weather satellites, providing up to seven levels of cloud cover.
XM WX Weather Features Echo Tops Echo Tops are derived from NEXRAD radar and indicate the highest altitude at which precipitation is falling. Echo Tops at or above the altitude you select are displayed in 5,000 foot increments up to 70,000 feet. Echo Tops can be helpful in determining the severity of thunderstorms, where higher altitudes equate to more intense thunderstorms. Echo Tops for All Altitudes Echo Tops at 15,000 Ft. Echo Tops at 20,000 Ft.
XM WX Weather Features Surface Pressure This feature displays pressure isobars and pressure centers. The isobars connect points of equal pressure. Pressure readings can help determine weather and wind conditions in an area. High-pressure areas generally are associated with fair weather. Low-pressure areas generally are associated with clouds and the chance of precipitation. Isobars that are packed closely together show a strong pressure gradient.
XM WX Weather Features Lightning Lightning bolt icons represent lightning strikes, as shown in the image below. Lightning strikes appear on the map if strikes have been detected within the last seven minutes. The ground-based lightning detection network only detects cloud-to-ground lightning. Lightning bolts indicate a cloud-to-ground lightning strike.
XM WX Weather Features Storm Cells The Storm Cells feature displays storms and the projected path of storms in the immediate future. Marine and automotive units also show the size of the storm cell. The direction in which the red cone is pointing (from the narrow end to the wide end) indicates the projected path of the storm cell. The red bars that span the cone indicate the projected area of the storm. Each bar represents 15 minutes. Aviation units show the direction of the storm with an arrow.
XM WX Weather Features Freezing Level Freezing Level shows contours for the lowest forecast altitude where icing conditions are likely to occur. Forecast Forecast displays fronts, high- and low-pressure centers, and city conditions. The forecast can be viewed in 12-hour increments for the next 48 hours.
XM WX Weather Features Fronts The Fronts feature displays the lines indicating the leading edge of an air mass that is replacing an existing air mass. This feature also displays pressure centers. Pressure centers are represented by a large red “L” for low-pressure centers or a large blue “H” for high-pressure centers. Pressure centers represent an area where pressure is measured to be either the highest or the lowest relative to the surrounding area. Indicates a low-pressure center.
XM WX Weather Features Hurricanes The Hurricanes feature shows the current position of a hurricane, a tropical storm, or a tropical depression, as well as its projected path (indicated by a red line). The darkened squares that appear along the red line indicate the projected locations received from the National Hurricane Center. The Center provides four forecasts at 12-hour intervals and a fifth forecast at a 24-hour interval.
XM WX Weather Features County Warnings When the National Weather Service issues a weather warning for a county, the county is highlighted with the color corresponding to the warning. To view information about the warning, select the county with the map pointer.
XM WX Weather Features XM Radio The XM Audio feature requires a subscription to XM Radio. (See page 7 for more information about subscribing to XM services.) You can scan channels by category and save them to a favorites list. You can turn the XM audio output on and off.
XM WX Weather Features Visibility Visibility is the forecasted maximum horizontal distance that can be seen at the surface. Contour lines on the Visibility display show the forecasted change in surface visibility. In the example below, visibility ranges from 1 mile to 4.5 miles. Visibility Contour Lines This image displays NEXRAD Radar, Satellite Mosaic, and Visibility. Displaying multiple features may help to provide a clearer picture of the weather conditions in the area.
XM WX Weather Features Water Temperature The Water Temperature feature displays the surface temperature of the water. Isotherm lines indicate the temperature breaks. Water Temperature 28 Wave Period The Wave Period feature provides the time (in seconds) between successive waves.
XM WX Weather Features Wave Direction The Wave Direction feature shows the direction in which waves are moving, as indicated by the direction of the red arrow. Wave Direction Wave Height The Wave Height feature displays wave heights. The wave heights for an area are separated by contour lines.
XM WX Weather Features Marine Warnings When a Marine Warning is issued, the area of the warning is highlighted in red. To view information about the warning, select the warning area with the map pointer.
XM WX Weather Features Buoy Reports Report readings are taken from buoys and coastal observation stations. These readings are used to determine air temperature, dew point, water temperature, tide, wave height and period, wind direction and speed, visibility, and barometric pressure.
