Aircraft Drawing Flashcards
What kind of parts can be represented by one-view drawings?
Parts with uniform thickness such as shims, plates, and gaskets.
What is the purpose of a schematic drawing?
Used to troubleshoot systems.
What is the name for a part that is used to bring out important details and how it is drawn?
A detailed view which is usually drawn to a larger scale than the main drawing.
How many views can be in a orthographic projection?
6
Describe a orthographic projection
It is a way of drawing an object using different views at right angles to each other, such as a top, front, and side view.
Describe the appearance of lines used to show hidden views, alternate positions and the middle of symmetrical objects and give their proper name.
Hidden views are a serious of short dashes. Alternate positions are one long and two short evenly spaced dashes. Center lines are alternating long and short dashes
How can you determine if a drawing has been changed?
listed in the revision block or ruled columns with revision numbers or notes listed
How are dimensions shown on aircraft drawings, and what is their purpose?
By numbers shown in the break of a dimension line . They represent the size of an object
What is an assembly drawing?
shows all the components of a part in an exploded form. A parts list is included
What is a detail drawing?
It includes all the information needed to fabricate the part.
What is a butt line?
A reference line to the right or left of the center line of the aircraft.
What is an installation drawing?
It shows the location of the parts and assemblies on the complete aircraft.
What is meant by “ clearance” when used on aircraft drawings?
An allowable dimension between two or more moving parts
What kind of information about an aircraft drawing can be found in the title block?
Drawing number, part or assembly name, drawing size, scale, date, name and address of company who made the part, name of draftsman and engineer approving the part
What information is contained in a “bill of material”?
A list of materials and parts needed to fabricate or assemble the part
What is the purpose of a center line on an aircraft drawing?
It divides a part into symmetrical halves.
How many views are required to represent the important details of most aircraft parts?
Three
Define tolerance used in aircraft drawing
Tolerance is the allowable dimensions of a part
Define clearance used in aircraft drawin
Is the dimension between to or more moving parts
Why are symbols used when drawing aircraft blue prints
Symbols are short hand to discover the component and the characteristics of the component
How many views are required to show the shape of an object
2 can be used by 3 may be necessary
