AvnWx.com is designed for use by pilots to quickly assess weather conditions in a local area. All weather information is retrieved in real-time from FAA and NOAA sources. To limit the amount of data retrieved from the servers, you'll specify your location and a distance around that location. This is done via the Location Bar. See Forms and Controls -- Location Bar help for details.
Double-clicking with the mouse will cause the map to re-center and gather data around the point where you clicked. This allows you to quickly get information for places without having to specify the specific city or airport code. Right-click on the map to bring up a context-sensitive menu to do the same thing.
Normally, passing your mouse over icons on the map will display weather information for that location. Single clicking on a METAR, PIREP, or TAF will result in detailed information being displayed in a pop-up Info Window. To update the Info Window, click on a different icon, or click on the detailed display itself to re-enable mouse roll-over. See Forms and Controls -- Info Window help for details. Winds aloft icons work in the same way.
If AIRMETs and SIGMETs are being displayed, when your mouse rolls within an advisory area, the area's border will highlight, and a summary of Inflight Weather Advisories will be shown in a display window. Single clicking on the map (but not on an icon) will cause detailed AIRMETs and SIGMETs to be displayed. Because AIRMETs and SIGMETs tend to cover large areas, you may find it convenient to "freeze" the report using a single click to disable the mouse rollover, and then zooming out the map (using the +/- controls in upper left, or +/- keys) to view the full extent of the advisory areas. You may need to scroll the browser window to view the full Inflight Weather Advisory report.Similarly, TFRs are displayed using borders, darker and thicker than those used for AIRMETs and SIGMETs. When your mouse rolls within a TFR are, the area's border will highlight and a summary of the TFR will be shown in a display window. Single clicking on the map (but not on an icon) when a TFR is displayed will cause the details to be displayed, and will "freeze" the report, allowing you to move the mouse without causing the report to update. You may need to scroll the browser window to view the full TFR. You may also click on the TFR's ID number to display information from the FAA's website. See Temporary Flight Restrictions for more information about TFRs. Right-click on the map, or on an icon to bring up a context-sensitive menu, allowing you to see more information about the selected item.
More information is available on the map's Forms and Controls, on the map's icons, and on the data sources.
