Utility Page
The
utility page
provides access to checklists, a
count down/up timer, trip timers, trip statistics, RAIM
(Receiver Autonomous Integrity Monitoring) prediction,
sunrise/sunset time calculations and software/database
version information.When a Utility item is selected, the
corresponding page will appear providing additional
information and features.
To select,

To select an item from the utility page:

actvate the flashng cursor.
2. Turn the
large right
knob to select the desred
menu opton, and press

The following items are available:
Checklists
— provides up to nine different user-
defined checklists containing up to 30 items each.
Flight Timers
— provides count up/down timers,
plus automatic recording of departure time and total
trip time. Departure and total trip time recording
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.
RAIM prediction only predicts the availability of
Fault Detection (FD) integrity in the absence of
WAAS corrections. It cannot predict the availability
of LPV approaches. The FAA provides a NOTAM
