Decision Support Imagery help


The decision support imagery page is designed to provide an image portal which displays static graphics for use in Impact-based Decision Support Services. The page will display a sample graphic once selection are chosen, and provide a URL link for that image at the bottom of the page. Start by selecting the product that will be displayed from the list of:

  • G-AIRMET - Graphical advisory of weather that may be hazardous to aircraft, but are less severe than SIGMETs.
  • WPC Prog Chart - Weather Prediction Centers Surface Analysis Prog Charts
  • SigWx - low level
  • SigWx - mid level
  • SigWx - high level
  • Turbulence - Graphical Turbulence Guidance product depictions which forecasts turbulence driven by, and synchronized with NOAA's "Rapid Refresh" of RAP forecast model.
  • Icing - The CIP and FIP graphics are computer-generated three-dimensional analyses of information related to the likelihood of encountering icing conditions.
  • TFM gate forecast - Traffic Flow Management gate forecast of significant weather in arrival and departure sectors for the top airports.
Once the first selection has been made, additional parameters will appear. Continue to make selections for each category. Note: Some selections cannot be paired and will be greyed out if unavailable.

The static image will appear at the bottom of the screen with the URL below it. Clear all selections by using the clear selections button, or reset some options by selecting a different product or new parameters.

Why can't I log in to my account?

Most features of do not require an account. If you are a pilot that previously had an account to submit PIREPs, please log in with your old username and password and you will be asked to reset your password the first time you log in.

If you are still unable to log in after following the steps in the confirmation email, please contact us for additional information.

Where is the METAR page?

The interactive Graphical Forecasts for Aviation observation tab displays METARs along with other current data including surface fronts and radar imagery. To view METARs alone, click on the Layers button at the top left corner of the map and deselect items you do not wish to view. Decoded METARs can be displayed by enabling the "decoded METARs" option in the Map Options under the gear icon on GFA.

Raw METAR data can be displayed by selecting the Products dropdown and selecting METAR data.

Where is the Satellite/Radar page?

Satellite and radar imagery are available on the observations tab of the interactive Graphical Forecasts for Aviation, that displays surface observations, imagery, fronts, and more in one place. Satellite imagery is an optional layer available from the layer selector in the upper right corner of the map. To display satellite or radr imagery alone, deselect items on the layer selector to simplify the display.

How do I submit PIREPs?

Please use the operational to submit PIREPs — this site is experimental. More information can be found found on the request page.

How do I access the Flight Path Tool?

The flight path tool is now embedded into the interactive Graphical Forecasts for Aviation map. Click on the route button along the right side of the map to open the display. Enter the airports to navigate, and select the product you wish to display from the dropdown. Watch a video on how to use the cross sections here.

Where is the HEMS (Helicopter Emergency Medical Services) tool?

The HEMS tool has been integrated into the interactive Graphical Forecasts for Aviation. Click on the helicopter button in the upper right part of the map to switch GFA from general aviation mode into low-altitude mode, which offers similar features as the HEMS tool.

What will happen to ADDS with this update

The ADDS static graphics are being phased out and replaced with the Graphical Forecasts for Aviation, which offers greater flexibility and configurability; some static graphics continue to be available for decision support. The ADDS Text Data Server has been succeeded by the Data API. Please let us know if you need assistance with the migration.
