SYSTEM OVERVIEW
Because of the tighter protection limit on approaches, there may be times when RAIM is not available. The
system automatically monitors RAIM and warns with an alert message when it is not available. If RAIM is not
predicted to be available for the final approach course, the approach does not become active, as indicated by the
messages “Approach is not active” and “RAIM not available from FAF to MAP”. If RAIM is not available when
crossing the FAF, the missed approach procedure must be flown.
