achieve the SAR target speed before reaching the start of the
search pattern.
— CHECK SPD/ALTITUDE LIMIT -- This is an alerting system
message indicating the upcoming speed and/or altitude
constraint must be checked and proper action taken in order to
meet the constraints.
— CHECK SPEED CONSTRAINT -- This is an alerting system
message indicating the aircraft is approaching a cruise or
descent speed constraint and the FMS has determined the
current deceleration rate is not sufficient to meet the constraint
speed.
— CHECK T/O ENVELOPE -- This is an alerting system message
indicating the pressure or density altitude is greater than
20,000 ft, the outside air temperature (OAT) is less than --40°C,
or the OAT is greater than the value obtained from the HD Limit

— CHECK VOR/DME X POSITION -- This is an alerting system
message indicating the radio position is out of limits and X
represents the radio number.
— CHECK *PD PLACEMENT -- This is an advisory operator
message indicating the waypoint was inserted someplace other
than the intended leg, as indicated by the entry.
— COMPARE FMS POSITIONS -- This is an alerting system
message indicating the positions of the FMSs have a difference
of greater than 1.5X the active RNP (required navigation
performance) value. The system continues to operate normally.
— COMPARE FUEL QUANTITY -- This is an alerting system
message indicating the FMS fuel quantity and the aircraft
reported fuel quantity are significantly different.
— CUSTOM DB SYNCHRONIZED -- This is an advisory system
message indicating the cross load of the custom database was
not done because the database was the same.
