ENT when finished. (To determine RAIM avail-
ability for your present position, press CLR,

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

tion. Once calculations are complete, the
400W-series unit will display one of the fol-
lowing 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 cover-
age within ±15 minutes of the specified arrival
date and time. Refer to the CDI/Alarms section
of Aux pages Setup 1 for specific information
