What are the 3 types of basic technical drawings used in the aviation industry?
Detail, Assembly, Installation
There are 13 specific types of lines used in typical aircraft drawings. If you wanted to find out what each line represents, where could you go for the information?
Each line type used in a drawing is in the legend and in the engineer’s description sometimes included to clarify any non-standard elements.
What is the purpose of section lines in a typical drawing?
A section line is an index that represent various materials used in a drawing in a cross section view.

What was the purpose of using the blueprint process in the past?
Blueprints are traditional drawings that are produced from regular black line on white paper. The process is nothing more than making a negative using the original drawing. This was a method for making duplicates before copies were available. Today, these technical drawings are reproduced using much less costly methods.
Do detail drawings have enough detail to be able to duplicate every aspect of a part?
Detail drawings contain all the required features and dimensions of parts, materials, finishes and special treatments. This is enough information to produce the part to specification.
What is the purpose of assembly drawings in maintenance manuals?
Assembly drawings depict the relationship between two or more parts. These drawings reference individual parts by their part number and specify the type and number of fasteners needed to join them.
What is the purpose of installation drawings and what important information do they provide?
Contain all subassemblies that are shown in their relative position in an exploded view. They are contain a bill of materials, dimensions for adjustment, and fasteners needed to complete the installation.
When would a sectional drawing be used?
Used when internal construction or shape cannot be seen by viewing the part directly. This type of drawing is helpful in determining the function of a part.
Exploded view drawings typically are the same drawings as what other type of drawing but used in a different document?
Exploded view drawings are common in Illustrated Parts Catalogs. Assembly drawings are used in Maintenance Manuals. Some manufacturers use the same drawings for both publications.
