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:
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 TEST website at http://sapttest.faa.gov.
All services currently hosted at raimprediction.net are being migrated to the http://sapt.faa.gov web site. When the migration is complete all services currently hosted at raimprediction.net will be discontinued. (Note that this will also affect all variations of raimprediction.net, including: www.raimprediction.net, raim-prediction.net and www.raim-prediction.net.)
The web site sapt.faa.gov currently hosts the ADS-B Service Availability Prediction Tool (SAPT), 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. Going forward, this site will host both the ADS-B prediction service and the RAIM prediction service.
The new web site, with integrated RAIM prediction services, will be operational soon. A test web site is presently available for use at:
New users may find the 'Getting Started' page for RAIM to be useful.
Please note that the new web site will host the automated, XML-based web service for RAIM route-of-flight predictions. However, the RAIM interactive flight planning form will be discontinued. More information about the XML web service is available at:
