Correct answer: A. To show the relationship of the various parts

  • A — correct An assembly drawing describes an object made up of two or more parts, and its primary purpose is to show the relationship of the various parts.
  • B — incorrect Size, shape, material, and methods of manufacture for a single part are given on a detail drawing.
  • C — incorrect Information for a part or assembly in its final installed position is the purpose of an installation drawing.

BACKGROUND

Drawings may be divided into three classes: detail, assembly, and installation. A detail drawing describes a single part, giving by lines, notes, and symbols the specifications for size, shape, material, and methods of manufacture. An assembly drawing describes an object made up of two or more parts; it describes the object's size and shape, and its primary purpose is to show the relationship of the various parts. An installation drawing includes all necessary information for a part or assembly in its final installed position in the aircraft. Assembly drawings are usually more complex than detail drawings and are often accompanied by detail drawings of the parts.

STUDY TIP

Match each class of drawing to its job: detail for making one part, assembly for how parts relate, installation for where the assembly goes in the aircraft.

KEY POINTS

  • Aircraft drawings fall into three classes: detail, assembly, and installation.
  • An assembly drawing's primary purpose is to show the relationship of the various parts.
  • Detail drawings cover a single part; installation drawings cover the installed position.
