Question 1

What is the procedure to be followed if, on a flight under IFR conditions using the NAVSTAR/GPS satellite navigation system, the number of satellites required to maintain the RAIM (Receiver Autonomous Integrity Monitoring) function are not available?

Accepted Answer

The flight may be continued using other certificated navigation systems

The flight may be continued as planned if at least 4 satellites are available and the pilot monitors the GPS-System manually

Answer

+/- 2NM or better for 75% of the flight time
