This website will be discontinued on January 30, 2015

(Note that this also affects all variations of raimprediction.net, including: www.raimprediction.net, raim-prediction.net and www.raim-prediction.net.)

All services currently hosted at raimprediction.net have been migrated to the SAPT (Service Availability Prediction Tool) web site located at: http://sapt.faa.gov

The SAPT web site hosts both the ADS-B SAPT and the migrated RAIM SAPT. (ADS-B SAPT is a service that is similar in concept to the RAIM prediction service but does not focus on either RAIM or the FAA Order AC90-100A.)

New users may find the Getting Started page for RAIM to be useful.

Getting Started with RAIM SAPT

The new web site hosts the automated, XML-based web service for RAIM route-of-flight predictions with an updated web service interface (WSDL). More information about the XML web service is available at:

RAIM XML Service

Note that the RAIM interactive flight planning form has been discontinued. However, the new web site provides the same RAIM graphical summaries that you are used to.

For more information or help with specific issues you may contact the SAPT team using the convenient online feedback form:

Some raimprediction.net web site features are presently functioning incorrectly. The issue is being actively investigated and a solution will be implemented as soon as possible. The following features are impacted and should be considered unreliable for navigation until a solution is implemented:

• Outage summary graphics and thumbnails
• Outages Java applet
• AC90-100 outages.dat file

Until the issues have been addressed, you are advised to use the raim prediction XML web service to check your flight plan for coverage. Some raimprediction.net features, such as outages.dat and the outage summary graphics, are available at the SAPT website at http://sapt.faa.gov.
