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.
If a 'WARN' annunciation appears at the
bottom left corner, GPS satellite coverage may
be sufficient, but the GPS 400 has detected a
position error which exceeds protection limits.
In this condition, all GPS navigation data on
the GPS 400 will be disabled. When either
'INTEG' or 'WARN' annunciation are shown,
use an alternate navigation source.
Trip Statistics— provides readouts for trip odometers, average speed and maxi-
mum speed. These readouts are resettable (individually or all at once) by press-
m
ing to display an options window.
RAIM Prediction— allows you to confirm that 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 the GPS 400
will have adequate satellite geometry to work with during your flight. RAIM
availability will be 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 GPS 400 will automatically monitor
RAIM during approach operations and warn you if RAIM is not available. In
such cases, use an external VOR receiver instead for many of the non-precision
approaches stored on your Jeppesen NavData® card. RAIM prediction will help
you plan for a pending flight to confirm GPS operation during an approach.
Sunrise / Sunset— allows you to calculate the time of sunrise and sunset at any
waypoint or your present position for a specified date.
Software / Database Ver.— provides software version information for the oper-
ating software within the GPS receiver, COM transceiver 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.
