FAA Aviation Mechanic General (AMG)Aircraft Drawings, Weight and BalanceEasy
A drafter produces a drawing that shows a single bracket completely dimensioned, including material, finish, and tolerances, with no other parts shown. What type of drawing is this?
- AInstallation drawing
- BDetail drawing
- CBlock diagram
- DAssembly drawing
Show answer & explanationAnswer & explanation
Correct answer: B. Detail drawing
A detail drawing depicts a single part completely, with all dimensions, tolerances, materials, and finish specifications needed to manufacture that part alone. Assembly and installation drawings show how multiple parts fit together rather than a single part's manufacturing detail.
Why the other options are wrong
- A. An installation drawing shows how a component is installed on the aircraft, not the part's manufacturing dimensions.
- C. A block diagram is a simplified schematic showing functional relationships, not manufacturing dimensions.
- D. An assembly drawing shows how multiple parts are put together, not a single part's full manufacturing detail.
Detail Drawing
A drawing that completely describes a single part, including dimensions, tolerances, material, and finish, sufficient for manufacture.
- Shows one part only
- Includes all dimensions and tolerances
- Contrasts with assembly drawings, which show multiple parts
Memory trick: Detail = one part, all the fine print.
