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 8.4 for
specific information regarding RAIM protection
limits, also refer to Section 13 for FDE (Fault
