RAIM Prediction
To predict RAIM availability:
1. Select “RAIM Prediction” from the utility
page.
2. The flashing cursor highlights the waypoint
field. Use the small and large right knobs
to enter the identifier of the waypoint at which
you wish to determine RAIM availability. Press
ENT when finished. (To determine RAIM avail-
ability for your present position, press CLR,
followed by ENT.)
3. The flashing cursor moves to the arrival date
field. Use the small and large right knobs to
enter the date for which you wish to determine
RAIM availability. Press ENT when finished.
4. The flashing cursor moves to the arrival time
field. Use the small and large right knobs
to enter the time you wish to use reference for
determine RAIM availability. Press ENT when
finished.
Once the destination, date and time are
entered, select “Compute RAIM?” to deter-
mine if satellite coverage is adequate for the
flight.
5. The flashing cursor moves to “Compute
RAIM?”. Press ENT to begin RAIM prediction.
Once calculations are complete, the 500W-
series unit displays one of the following in the
RAIM status field:
•RAIM Not Available —
Satellite coverage is predicted to NOT be
sufficient for reliable operation during non-
precision approaches
•RAIM Available —
Satellite coverage is predicted to be sufficient
for reliable operation during all flight phases,
including non-precision approaches
NOTE: RAIM computations predict satellite coverage
within ±15 minutes of the specified arrival date and
time. Refer to Section 11 for more information regard-
ing RAIM protection limits.
