Aircraft Drawings
3 Types of Working Drawings
What is Detail, Assembly, & Installation?
A thick, solid outline used to describe the shape of an object.
What is a visible line?
The difference between the extreme permissible dimensions a part may have and still be acceptable.
What is tolerance?
These areas of the aircraft are especially prone to corrosion.
What is the engine exhaust area, battery compartment, landing gear, or any fayed surfaces?
This chemical treatment process increases corrosion resistance and pain bonding qualities by slightly roughing the surface.
What is alodizing?
Shows the required wire size for a given installation.
What is a Wire Diagram?
A medium, dashed line used for an edge that is not visible to the viewer.
What is a hidden line?
Contains information pertinent to the drawing.
What is a title block?
These 4 things are required for galvanic corrosion to occur.
What are anode, cathode, electrolyte, and electrical contact between anode & cathode?
The mechanical removal of corrosion from magnesium parts should be limited to the use of this part.
What is a stiff, non-metallic brush (hog bristle brush)?
Aids in the tracing, function, and troubleshooting of a circuit.
A thin, alternating long & short line.
What is center line?
A list of materials required to make a part.
What is bill of materials?
This type of corrosion usually occurs from exposure to environmental elements or caustic solvents. They can be identified as rough, etched, or pitted appearance on the surface. It is usually accompanied by powdery dust.
What is surface corrosion?
Any corrosion on the surface of a highly stressed steel part is potentially dangerous. You can use this tool to remove the corrosion.
What is fine-grit aluminum oxide paper?
6 Basic Shapes Composed in Sketches
What is a Triangle, Circle, Cube, Cylinder, Cone, and Sphere?
A thin, solid line that extends out from where a measurement is taken.
What is an extension line?
This is used to locate parts, sections, and views on large drawings.
What are zone numbers?
This type of corrosion occurs in metals that have not been properly treated before the painting process causing the metal to corrode underneath the protective coating resulting in blistering or worm-like formation lines.
What is filiform corrosion?
This form of corrosion occurs between closely fitting assembled parts that have a slight amount of relative motion.
What is fretting corrosion?
The type of drawing that shows the relationship of parts and can be helpful in assembling components?
What is Exploded View Drawing?
A thin, solid line between the extension line with space for the measurement?
What is a dimension line?
A type of drawing is used to show each item's relationship and function in a diagram.
What is a block diagram?
The most severe form of intergranular corrosion.
What is exfoliation?
This condition is a result of the used of unapproved cleaners on an aircraft.
What is hydrogen embrittlement?
