rectifier, synchro, motor transducer, and digital logic block. However, the learning objectives of
the Class A School should be the determining factor for the depth of coverage.
3.6.4.2.3 Detailed functional elements. When functional elements are new, unusual, or complex
in design and therefore require more detailed coverage, such coverage may be presented at one
time and not in a straightforward sequence with respect to each individual signal flow diagram. In
such instances, specific paragraph references shall be provided in logical functional sequence with
respect to each individual signal flow diagram. In such instances, specific paragraph references
shall be provided in logical functional sequence for all out-of-sequence text material. Typical
examples are as follows:
a. Unusually lengthy descriptions of complex functional elements (circuitry or mechanism)
should be deferred as amplifying information if such descriptions would tend to obscure the
continuity of an overall description.
b. Complex functional elements having identical multiple applications, or one application
contributing to two or more output functions, shall be fully described only once and otherwise
covered by references to that point in the text.
3.6.4.3 Functional description continuity. The continuity of the general and detailed functional
descriptions shall be such that summarizing is not required for understanding combined functions
of the equipment as operated in the intended weapon system application. In instances where the
various functional units may, by multiple switching, assume a variety of configurations, coverage
shall be accomplished by assuming each of the various possible conditions and describing only the
modified portion of the signal path, action, or information flow. Illustration of alternate
configurations shall be limited to that required to integrate signal modification and control.
3.6.4.4 Detailed analysis. A detailed analysis shall be provided for areas of new, unusual, or
complex design. Descriptions of conventional circuits or devices that are covered in Navy Class
A training shall be included only to the depth required to integrate them into the overall analysis.
3.6.4.4.1 Detailed analysis text. Detailed analysis text shall be supported as appropriate by
detailed logic diagrams and partial electrical, electronic, pneumatic, hydraulic and mechanical
schematics (see MIL-DTL-24784). Detailed logic diagrams shall include the level of detail
specified in IEEE 991. Detailed mechanical analysis descriptions shall be supported as
appropriate by mechanical schematics, gearing and linkage diagrams. Cutaway views shall show
internal parts of complex mechanisms in the detail necessary to ensure comprehension of a
detailed mechanical analysis. Callouts shall be used to locate each functionally significant part.
3.6.4.4.2 Mathematical analysis. Mathematical analysis shall be provided for equipment
elements that perform mathematical functions, such as fire control, guidance, and computer
equipment, in sufficient detail that shall provide the technician or trainee with a complete
understanding of the mechanics of the equipment performing the function. Mathematics shall be
limited to the level of high school algebra, geometry, and trigonometry. However if a higher level
of mathematics is required for a valid definition, it shall be presented in the simplest possible
