Whenever you evaluate the operational readiness ofyour personnel, you should ensure that they are familiarwith the following topics:llllIntended purpose of all switches, indicators,controls, and the impact each has on othersubsystems or combat system equipmentsCommunication links available at the station andwith the other stationsKnowledge of and compliance with specifiedcommunication disciplinesKnowledge that the lack of communicationdiscipline is an internal hazard to the combatsystem or to the shipTEST SELECTION AND SCHEDULINGWith the coming of PMS, an integrated approach totesting was developed. This approach is based ondefining all functional test requirements and subjectingthem to a critical examination. The examinationinvolves an engineering analysis in which each function,parameter, and characteristic is examined for its (1)importance to mission or mode performance, (2)reliability based on the circuit elements that affect thefunction and (3) expected mean time between failures.This places a test periodicity (daily, weekly, monthly,quarterly, semiannually, annually, and cyclically) on thefunctions. Critical functions are assigned a highperiodicity, regardless of reliability; while less criticalfunctions may be assigned a lower periodicity based ontheir reliability. Related functions are grouped byperiodicity and functional interdependency so that theymay be tested by appropriate periods. This integratedtesting concept results in a management problem that isa SERT responsibility.The tactical situation governs how and whenmaintenance is scheduled. Scheduling is a criticalelement of preventive maintenance management andrequires a thorough knowledge of the intent andconditions of each maintenance requirement card(MRC). Important conditions include in-port and at-searequirements, outside service requirements,navigational support requirements, combat systemoperational usage, ship control requirements, emissioncontrol conditions, computer program requirements,subsystem interdependency, impact on computerprogram capability, adverse weather conditions, timerequirements, and manpower requirements. From theseconditions, the quarterly schedule can be developedbased on the ship’s employment schedule. Heavymaintenance is usually scheduled during in-port periodsand independent ship exercises during nonthreatconditions (particularly for those procedures requiringlong periods of operational equipment downtime). If theemployment schedule changes, the PMS schedule mayrequire modification. Daily and weekly schedules arebased on the ship’s readiness condition and operationalsituation. Subsystem interdependence and manpowerusage are also critical in scheduling.Preventive maintenance management includes thefollowing requirements:1.2.3.4.5.6.7.Ensuring that events take place as scheduledCoordinating manning and equipmentavailability for interdependent testingProviding adequate safety measuresEnsuring the availability of required supportingsystemsCoordinating the actions of command andtactical operation personnelEnsuring fault isolation and correctivemaintenance follow-upEnsuring the completion of required reportsThe ship’s CSTOM contains readiness assessmentand fault isolation diagrams indicating the test thatrequires the fewest ship resources, verifies each combatsystem interface function, and aids the SERT inpreventive maintenance management.READINESS ASSESSMENT REPORTINGAfter readiness assessment is completed, readinessstatus must be reported in a form that is brief and easilyunderstood and that presents a clear picture of thecombat system effectiveness. This is done mosteffectively by addressing the status of a major functionas it relates to a mission capability. Figure 4-7 shows asample method of presenting a mission summary reportof a four-state qualitative functional readinessassessment. This summary report sample also providesa brief description of the effect each subfunction faulthas on the major fictional. Supporting information onspecific subfunction faults related to the summary reportsample can be provided in a combat system daily faultreport form. Figure 4-8 shows a sample method ofpresenting daily fault information. Report forms of thistype (or a similar type) should be developed by the SERTto fit the ship’s requirements. The combat system dailyfault report is the responsibility of the SERT and should4-18
