REQUIREMENTS
3
3.1 General requirements.
3.1.1 Preparation requirements. The general manner of preparation and format for all manuals shall be in
accordance with the requirements of MIL-STD-38784, except as modiied herein.
3.1.2 Nomenclature requirements. System/subsystem nomenclatures assigned in accordance with
MIL-STD-1808 shall be followed by the applicable higher level designation in a parenthesis (ref:
MIL-HDBK-863). Nomenclature shall agree with the drawing title and shall be forward reading.
Chapter/Section titles shall correspond with chapter/section requirements speciied herein. Nomenclature shall
be used consistently throughout a chapter for text and illustrations. Nomenclature appearing on decals,
engraved legends, nameplates, or other markings shall be repeated verbatim on the irst occurrence. All
attaching hardware items involved in a task shall be speciically mentioned.
3.1.2.1 Short form use of common names. After irst use, nomenclature shall be shortened as required, if
there is no other name with which it can be confused. Simple identifying nomenclature shall be provided
for attaching parts in both pictorial callouts and text, if appropriate.
3.1.2.2 Terminology. Only terminology that conveys the purpose, function, or nature of an item relevant to
the task shall be used. Modiiers shall be used when one or more items of the same object nomenclature
are acted upon in the same task. For example: A procedure to rig a spoiler center wing input quadrant
includes an illustration of the unit. The presence of the illustration showing the location of the unit
enables the writing of a simple task step, e.g., "Insert rig-pin." If more than one rig-pin exists, a proper
modiier shall be added, e.g., "Insert lower rig-pin."
3.1.3 Diagrams. Equipment wiring data and schematic diagrams shall be developed in accordance with
MIL-HDBK-863. Parallel lines on wiring data and schematic diagrams shall in no case be less than 0.10
inches apart and no less than 0.06 inches high when reduced to printed size.
3.1.4 Foldout pages. Print media requirement: Foldout pages shall be in accordance with MIL-STD-38784,
unless otherwise speciied herein. SSSN, igure number, and igure title for foldout pages shall be placed so
they are visible when the printed page is folded.
3.1.5 Marginal copy. Print media requirement: The SSSN shall appear in the lower-outer corner of each
page, directly above the page number and shall be 18-point type. The SSSN shall not be placed
at the bottom of front matter pages.
3.1.6 Numbering. Chapters, sections, paragraphs, pages, igures, and tables shall be numbered in accordance
with MIL-STD-38784, except as speciied herein. The SSSN shall form a part of the paragraph heading
when the heading introduces an item having an SSSN assigned, e.g., "1-17 Null Ampliier (03-17-04)."
3.1.6.1 Use of SSSN. The SSSN shall be used as described in the following paragraphs and MILSTD-
1808. When used for electronic data, the SSSN shall be used in task oriented view packages.
3.1.6.1.1 Use of "System" number. The system number is used to denote a chapter in General Equipment
(GE), Fault Reporting (FR), and Fault Isolation (FI) manuals. In General System (GS) manuals, the system
number is used to denote a manual (if separate manuals) or a chapter (if combined manuals). For Job Guide
(JG) manuals, the system number designates the manual chapter as speciied herein (see 3.4.3). Systems
which are reserved or not used shall not be included in the manuals (see 3.2.3.2).
3.1.6.1.2 Use of "Subsystem" number. The subsystem number is used to denote a section in the GE, FR,
and FI manuals. In GS manuals, the subsystem number is used as a reference only. For Job Guide (JG)
manuals, the system number designates a chapter within the manual(s) for that system. The contents of the
chapter or section and the system separations are assigned by MIL-STD-1808. The application of the
subsystem designator as shown herein must be conined to discussion of the total subsystem; e.g., material
contained in 34-50 would necessarily be conined to general discussion of the total Dependent Position
Determining subsystem and requires the addition of zeros in the third element (34-50-00).
3.1.6.1.3 Sub-subsystem numbering. The sub-subsystem number is assigned by the manufacturer. Subsystems
which contain very complex sub-subsystems may require further chapter breakout. This will be indicated by
the fourth digit, such as 34-51-00. In this case, -51 would be a sub-subsystem of the Dependent Position
