3.6.2.3.4 Introduction. The introduction shall define the system and its relationship with other
systems. The mission of the system shall be stated. The text shall be supported by a diagram (see
MIL-DTL-24784) showing the interrelationships of the system equipments (see figure 20-30).
The major functional relationship and inputs and outputs to related systems shall be indicated.
3.6.2.3.5 Physical arrangement. System areas and compartments shall be described and the
system equipment and units contained in the areas shall be listed. The physical arrangement
description shall be supported by the following illustrations:
a. An inboard profile drawing of the ship or stations showing compartment locations and
identifying topside equipment and equipment units comprising the system (see figure 20-31).
b. Separate illustrations of each compartment and area, identifying the listed system equipment
(see figure 20-32). Other equipment, which is installed in the subject system compartments
and areas, need not be listed in the text or called out in the illustrations if they do not directly
affect the operation or maintenance of the subject system.
3.6.2.3.6 System equipment description. Each of the equipment comprising the system shall be
identified and described. Descriptions of operator-attended equipment shall include general
statements as to the nature and purpose of units and indicators. The text shall be supported by
illustrations. All equipment shall be shown, whenever possible, in relative-scale proportion. An
equipment may be separately illustrated with significant features called out, if such details are
necessary for proper support of the text.
3.6.2.3.7 Associated system equipment. When required, descriptions and illustrations of
associated system equipment shall be limited to the major units thereof. The descriptions shall be
more condensed than those of subject system equipment; otherwise, the same requirements are
applicable. In the descriptions, emphasis shall be placed on those associated systems equipments
that constitute operational or functional interfaces with the subject system. Such units shall be
included in the system illustrations.
3.6.2.3.8 Equipment illustrations. Equipment illustrations shall be in accordance with
MIL-DTL-24784.
3.6.2.3.9 Reference data. Reference data, equivalent to the following, shall be included in
tabular form:
a. Descriptive (identification plate data) which identifies manufacturer, type, model, part or
identifying number (PIN), Joint Electronic Type Designation (when applicable), repairable
identification code (RIC) and allowance parts list (APL), as applicable.
b. Functional characteristics, such as: power requirements, horsepower, pressure, capacity,
modes of operation, power output, frequency, pulse characteristics, sensitivity, selectivity,
including tolerances, where applicable.
c. Capabilities and limitations, such as: pounds of thrust, knots, turning radius, minimum and
maximum ranges, degree of coverage, resolution, accuracy.
