5.2-1 Critical Parameter Monitoring Support

The system should assist the user in monitoring critical parameters, especially parameters that change very rapidly or very slowly, by alerting the user when values are out of range.

Additional Information:
The user may not be able to maintain attention on the slow-changing indication due to competing task demands and, thus, may not be aware that the parameter is out of range. For rapidly changing parameters, the unacceptable range might be reached before the user is able to begin monitoring the parameter. Setpoints used to indicate a change in status should be chosen to provide users with sufficient time to respond appropriately.
