RAIM Prediction — predicts if GPS coverage is
available for your current location or at a specified
waypoint at any time and date. Receiver Autonomous
Integrity Monitoring performs checks to ensure that

in Oceanic, En Route and Terminal phases of flight.
Because the FAA’s TSO requirements for non-precision
approaches specify significantly better satellite cover-
age than other flight phases, RAIM may not be avail-
able when flying some approaches. The 500W-series
unit automatically monitors RAIM during approach
operations and warns you if RAIM is not available.

instead for the approaches. RAIM prediction helps you
plan for a pending flight to confirm GPS operation
during an approach.

An “INTEG” annunciation at the bottom left corner of the
screen indicates that satellite coverage is insufficient to pass
built-in receiver autonomous integrity monitoring (RAIM)
tests. When this occurs, the GPS receiver continues to provide
navigation information, but should not be used for primary
navigation guidance. Use the GNS 530W’s VLOC receiver or
another suitable navigation source.
