can be conﬁgured to run either any time 400W-

series power is on, or only when your ground speed

exceeds 30 knots.

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 cover-

age 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 the 400W-series unit has adequate

satellite geometry during your ﬂight. RAIM avail-

abilityisnear100%inOceanic,EnRouteand

Terminal phases of ﬂight. Because the FAA’s TSO

requirements for non-precision approaches specify

signiﬁcantly better satellite coverage than other

ﬂight phases, RAIM may not be available when

ﬂying some approaches. The 400W-series unit

automatically monitors RAIM during approach

operations and warns you if RAIM is not available.

Insuchcases,usetheGNS430W’sVLOCreceiver

instead for the approaches. RAIM prediction helps

you plan for a pending ﬂight to conﬁrm GPS opera-

tion 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 will continue to

provide navigation information, but should not be used for

primary navigation guidance. Use the GNS 430W’s VLOC

receiver or another suitable navigation source.

Sunrise / Sunset—

allows you to calculate the time

of sunrise and sunset at any waypoint or your pres-

ent position for a speciﬁed date.
