Through its JetPlan flight planning service, Jeppesen for the last couple of years has been offering RAIM (receiver autonomous integrity monitoring) prediction reports to customers who use its JetPlan flight planning service. The Colorado firm is reminding pilots who use GPS Rnav for primary navigation about a new U.S. requirement for such reporting that went into effect on March 31. RAIM is a technology that assesses the integrity of GPS signals, ensuring they can be used for navigation. Jeppesen said customers can plan their flight using JetPlan and then with one click submit a RAIM prediction request. The system then uses “sophisticated algorithms to generate a prediction for the entire route” including departure and arrival airports. Other companies, including avionics makers Rockwell Collins and Universal Avionics, offer RAIM prediction services, “but none are fully integrated with a flight planning system” like the JetPlan service is, Jeppesen said.
