Question 10

What type of drawing line consists of alternating long and short lines?

Answer 10

Center.

Question 11

(1) A measurement should not be scaled from an aircraft print because the
paper shrinks or stretches when the print is made.

Answer 11

both No. 1 and No. 2 are true.

Question 12

1. Sketches are usually made with the aid of drafting instruments.
2. Sketches are usually more complicated to make when using graph paper.

Question 16

What is the class of working drawing that is the description/depiction of a single part?

Answer 16

Detail drawing

Question 17

(1) According to 14 CFR Part 91, repairs to an aircraft skin should have
a detailed dimensional sketch included in the permanent records.
(2) On occasion, a mechanic may need to make a simple sketch of a proposed
repair to an aircraft, a new design, or a modification.
Regarding the above statements,

Answer 17

only No. 2 is true

functional location of components within a system.

Question 21

In the reading of aircraft blueprints, the term “tolerance”, used in association with aircraft parts or components,

Answer 21

is the difference between extreme permissible dimensions that a part may have and still be acceptable.

Question 22
