FAA Aviation Mechanic General (AMG)Aircraft Drawings, Weight and BalanceEasy
A technician reviewing an engineering drawing wants to find the drawing number, revision letter, scale, and the name of the part depicted. Where on the drawing is this information found?
- ANotes section
- BTitle block
- CBill of materials
- DZone chart
Show answer & explanationAnswer & explanation
Correct answer: B. Title block
The title block, typically located in the lower right corner of an engineering drawing, contains identifying information such as drawing number, revision, scale, part name, and drafter/approval data. The bill of materials lists parts and quantities, not drawing identification data.
Why the other options are wrong
- A. A notes section provides special instructions, not standard identification data.
- C. The bill of materials lists parts, quantities, and materials, not drawing identification.
- D. A zone chart locates structural areas on the aircraft, unrelated to drawing IDs.
Title Block
A standardized box, usually in the lower right corner of a drawing, containing identifying information such as drawing number, revision, scale, date, and part name.
- Located in lower right corner by convention
- Includes drawing number, scale, revision letter, date, drafter
- Distinct from bill of materials which lists parts/quantities
Memory trick: Title block = the drawing's 'ID card' in the corner
