5.10 RAIM PREDICTION
RAIM (Receiver Autonomous Integrity Monitoring) is a GPS receiver function that performs a consistency
check on all tracked satellites. RAIM ensures that the available satellite geometry allows the receiver to calculate
a position within a specified RAIM protection limit (2.0 nm for oceanic, 2.0 nm for enroute, 1.0 nm for terminal,
and 0.3 nm for non-precision approaches). During oceanic, enroute, and terminal phases of flight, RAIM is
available nearly 100% of the time. The RAIM prediction function also indicates whether RAIM is available at a
specified date and time. RAIM computations predict satellite coverage within ±15 min of the specified arrival
date and time. Because of the tighter protection limit on approaches, there may be times when RAIM is not
available. RAIM prediction must be initiated manually if there is concern over SBAS coverage at the destination
or some other reason that compromises navigation precision. If RAIM is not predicted to be available for the
final approach course, the approach does not become active. If RAIM is not available when crossing the FAF, the
missed approach procedure must be flown.
