Utility Page:  RAIM Prediction
To predict RAIM availability:
1. Select “RAIM Prediction” from the Utility page, using the steps described on page 122.
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 availability 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
for which you wish to determine RAIM availability. Press ENT when finished.
5. The flashing cursor moves to “Compute RAIM?”. Press ENT to begin RAIM prediction. Once calculations are
complete, the GPS 500 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 page 129 for more information regarding RAIM protection limits.
Utility Page:  Software / Database Versions
The Software / Database Versions page displays software version information for each of the various
subsystems contained within the GPS 500, as well as database versions for the Jeppesen NavData® card

STEP 5: Once the destination, date and time are
entered, select “Compute RAIM?” to determine if
satellite coverage is adequate for the flight.
The Software / Database Versions page displays the
internal software versions for the GPS 500’s various
subsystems as well as the Jeppesen database and
