Jeppesen is the first and only commercial provider to receive operational approval from the Federal Aviation Administration (FAA) for its Receiver Autonomous Integrity Monitoring (RAIM) prediction report. RAIM is a technology developed to assess the integrity of GPS signals, and thus, the accuracy of airborne GPS navigation equipment.

Effective October 1, 2008 FAA is requesting aircraft operators and pilots who operate in US terminal and enroute RNAV environments, and who use GPS as a primary navigation method, obtain a RAIM prediction report prior to flight. On July 1, 2009 FAA is planning to mandate RAIM prediction for those operators mentioned above.

The Jeppesen RAIM prediction report is unique because it is fully integrated with Jeppesen’s flight planning systems. Customers can plan their route of flight and with one click submit a RAIM prediction request. The system then uses sophisticated algorithms to generate a prediction for the entire route, including the departure and arrival airports. Customers can request RAIM prediction for individual airports as well. Other RAIM prediction services are available, but none are fully integrated with a flight planning system like the Jeppesen service is. Jeppesen has teamed with DWI, the company that provides a similar RAIM prediction solution for EuroControl, to deliver the Jeppesen RAIM prediction report.

If any section of the route has an outage lasting longer than five minutes, the section of the route and timeframe are highlighted in the report. If there are no outages, the report simply states that a check was performed and no outages are expected. The route will need to be re-planned if an outage is predicted to last beyond five minutes.
