3 REQUIREMENTS

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 modified herein.

3.1.2 Nomenclature requirements. System/subsystem nomenclatures are assigned in accordance with MIL-STD-1808. (For guidance on higher level designation see MIL-HDBK-863.) Nomenclature shall agree with the drawing title and shall be forward reading. Chapter/Section titles shall correspond with chapter/section requirements specified 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 first occurrence. All attaching hardware items involved in a task shall be specifically mentioned.

3.1.2.1 Short form use of common names. After first 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. Modifiers 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 modifier shall be added, e.g., "Insert lower rig-pin.”

3.1.3 Diagrams. MIL-HDBK-863 may be referred to for development of equipment wiring data and schematic diagrams.

Print presentation: 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 presentation: Foldout pages shall be in accordance with MIL-STD-38784, unless otherwise specified herein. SSSN, figure number, and figure title for foldout pages shall be placed so they are visible when the printed page is folded.

3.1.5 Marginal copy. Print presentation: 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, figures, and tables shall be numbered in accordance with MIL-STD-38784, except as specified 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 Amplifier (03-17-04).”

Electronic presentation: Page count restrictions do not apply.

Print presentation: All pages shall be numbered in accordance with MIL-STD-38784.

3.1.6.1 Use of SSSN. The SSSN shall be used as described in the following paragraphs and MIL-STD-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 specified 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 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 confined to discussion of the total subsystem; e.g., material contained in

34-50 would necessarily be confined 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 Determining subsystem of the Navigation System. A sub-subsystem shall not be identified in the second element unless a fourth designator, different from zero (0), is assigned.

3.1.6.1.4 Task/component number numbering. This number is assigned by the manufacturer to a specific task or component. This number shall be assigned in consecutive order within the manual or view package in which it is used. For example, the fifth component covered in a JG would be XX-XX-05-XXX.

3.1.6.1.4.1 Task/component number development for JG, FR and FI Manuals. The subject number assignment shall reference the SSSN in the terminal steps of the fault tree contained in the FR and FI Manuals.

For example: If an FR or FI page/screen contains fault tree segments applicable to a specific item of a sub-subsystem of the Dependent Position Determining subsystem, the page/screen would reflect 34-51-00;

if a page/screen contains segments of the fault tree applicable to more than one subject (general) breakdown of the Dependent Position Determining subsystem, the page/screen would reflect 34-50-00; if the page/screen contains segments of the fault tree applicable to multiple subsystems within the Navigation system, the page/screen would reflect 34-00-00.

Electronic presentation: SSSN shall be viewed in the persistently viewable area on the screen. The word “page” shall be synonymous with scrollable view.

Print presentation: The SSSN shall be reflected in the lower outer corner of the FR and FI Manuals. The number shall reflect the first three elements, to the lowest element possible, as allowed by the composition of the segment of the fault tree displayed on that page.

3.1.6.1.4.2 Subject number development for other than JG, FR and FI Manuals. When used in view packages or other manuals, the task/component number is assigned in sequence of the system. This number is developed for manuals other than the JG, FR and FI Manuals, are similar manner.

3.1.6.1.5 Function number. The function number (fourth element) shall be assigned as specified herein.

3.1.6.1.5.1 Function number requirements for JG Manuals. The assignment of the function number shall follow the task/component number in the JG Manual and shall be assigned as specified herein. For example, a system operational checkout will be identified as "XX-XX-XX-001."

3.1.6.1.5.2 Typical functions. The following functions shall be used for development of the function numbers and may be expanded/changed to suit equipment requirements if approved by the acquiring activity (see 3.4.3.2.1):

001 - Operational Checkout 008 - Cleaning

002 - Access 009 - Lubrication

003 - Remove 010 - Servicing

004 - Install 011 - Jacking

005 - Repair 012 - Alignment and Adjustment

006 - Rigging 013 - Calibrate
