Pictorial
Which type of wiring diagram shows the outline of a ship or aircraft or other structure, and the location of equipment such as panels, connection boxes, and cable runs? (Page 6-1)
Isometric
Which type of diagram uses lines and graphic symbols to simplify complex circuits or systems? (Page 6-1)
Single-line
Which type of diagram uses graphic symbols to show how a circuit functions electrically? (Page 6-1)
Schematic
Which type of wiring diagram shows how each individual conductor is connected within the various connection boxes of an electrical circuit or system? (Page 6-1)
Elementary
Which type of diagram are the major components of equipment or a system represented by squares, rectangles, or other geometric figures, and the normal order of progression of a signal or current flow is represented by lines? (Page 6-1)
Block
All similar units in the ship comprise a group, and each group is assigned a separate series of consecutive numbers beginning with what? (Page 6-1)
1
What embossed with the cable designations are used to identify all permanently installed shipboard electrical cables? (Page 6-2)
Metal tags
Navy ships use two systems of cable marking; the old system on prior to ships built in what year, and the new system on those built since then? (Page 6-2)
1949
The new cable tag system consists of three parts in sequence; source, voltage, and what else, and where practical, destination? (Page 6-3)
Service
Neutral polarity, where it exists, is identified by the conductor of what color? (Page 6-4)
White
What is the actual installation diagram for the deck or decks shown and is used chiefly in ship construction? (Page 6-5)
Wiring deck plan
Wiring deck plans are drawn to scale (usually 1⁄4 inch to the foot), and they show the exact location of all fixtures. One blueprint usually shows from 150 to how many feet of space on one deck only? (Page 6-5)
200
Which type of diagram for a particular piece of electrical equipment shows the relative position of the various components of the equipment and how each individual conductor is connected in the circuit? (Page 6-6)
Wiring
Which type of diagram describes the electrical operation of a particular piece of equipment, circuit, or system? (Page 6-7)
Electrical schematic
What are similar to electrical prints, but they are usually more difficult to read because they represent more complex circuitry and systems? (Page 6-11)
Electronics prints
What system is an electronic air navigation system that provides a properly equipped aircraft with bearing and distance from a shipboard or ground radio beacon selected by the pilot? (Page 6-11)
TACAN
Electronic schematic diagrams use graphic symbols from what for all parts, such as tubes, transistors, capacitors, and inductors? (Page 6-12)

What is a combination of letters and numbers used to identify the various parts and components on electronic drawings, diagrams, parts lists, and so on? (Page 6-16)
Reference designation
What is defined as two or more sets and other assemblies, subassemblies, and parts necessary to perform an operational function or functions? (Page 6-17)
System
What is defined as one or more units and the necessary assemblies, subassemblies, and parts connected or associated together to perform an operational function? (Page 6-18)
Set
Individual conductors connecting to terminal boards are tagged with a vinyl sleeving called what that shows the terminal board and terminal to which the outer end of the conductor is connected? (Page 6-20)
Spaghetti
Aircraft electronic wiring diagrams fall into two basic classes: chassis wiring diagrams and which other type of diagrams? (Page 6- 21)
Interconnecting
