RAIM Prediction— predicts if GPS coverage is available for your current location or
at a specifi ed waypoint at any time and date. Receiver Autonomous Integrity Monitoring
performs checks to ensure that the GNS 430 will have adequate satellite geometry during
your fl ight. RAIM availability will be near 100% in Oceanic, En route and Terminal phases
of fl ight. Because the FAA’s TSO requirements for non-precision approaches specify
signifi cantly better satellite coverage than other fl ight phases, RAIM may not be available
when fl ying some approaches. The GNS 430 will automatically monitor RAIM during ap-
proach operations and warn you if RAIM is not available. In such cases, use the GNS 430’s
VLOC receiver instead for many of the non-precision and precision approaches stored on
your Jeppesen NavData® card. RAIM prediction will help you plan for a pending fl ight to
confi rm GPS operation during an approach.
Sunrise / Sunset— allows you to calculate the time of sunrise and sunset at any way-
point or your present position for a specifi ed date.
Software / Database Ver.— provides software version information for the operating
software within the GPS receiver, COM transceiver, VOR/localizer receiver, glideslope
receiver and main processor board. The software / database version page also displays the
current Jeppesen database type and expiration date, along with the version and type of
built-in land database.

An ‘INTEG’ annunciation at the bottom left
corner of the screen indicates that satellite
coverage is insufficient to pass built-in receiv-
er autonomous integrity monitoring (RAIM)
tests. When this occurs, the GPS receiver will
continue to provide navigation information,
but should not be used for primary navigation
guidance. Use the GNS 430’s VLOC receiver
or another suitable navigation source.
If a ‘WARN’ annunciation appears at the
bottom left corner, GPS satellite coverage
may be sufficient, but the GNS 430 has
detected a position error which exceeds
protection limits. In this condition, all GPS
navigation data on the GNS 430 will be dis-
abled. Use the GNS 430’s VLOC receiver or
an alternate navigation source.
