Trip Statistics — provides readouts for trip odom-

eters, average speed and maximum speed. These

readouts are resettable (individually or all at once) by

pressing MENU to display an options window.

RAIM Prediction — predicts if GPS coverage is

available for your current location or at a speciﬁed

waypoint at any time and date. Receiver Autonomous

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.

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.
