Study Notes
Methods of Illustration
- The complete sectional view allows only the inside to be seen.
- Half-section view, a combination of internal and external views, shows the inside and outside of a part at the same time.
- Block diagrams are used to aid in troubleshooting, consisting of individual blocks representing several components or replaceable modules.
- Logic flow charts are used to identify and replace malfunctioning sub-assemblies, following a logical testing sequence.
- Wiring diagrams are used to troubleshoot electrical systems, containing schematic diagrams, part numbers, and locations of components.
- Schematic diagrams are used to illustrate a principle of operation, indicating the location of components with respect to each other.
- Pictorial diagrams are used to visualise the operation of a specific system, containing pictures of components instead of electrical symbols.
Methods of Dimensioning
- Dimensions on a drawing represent the perfect size and are called basic or nominal dimensions.
- Dimensions are used to show the shape of a part and accurately give all needed dimensions.
Drawing Systems
- The grid system is used to locate detailed views on large drawings, divided into zones identified by letters and numbers.
- Revision blocks are used to indicate revisions, including the description of the revision, date, and approver's initials.
Standards and Specifications
- International Standards and ISO Standards are documented agreements containing technical specifications or other precise criteria to ensure materials, products, processes, and services are fit for their purpose.
- The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies.
- ISO 9000 is the family of quality management systems standards, and ISO 9001 deals with the requirements that organisations must fulfil.
Aviation Standards
- Aviation standards include Airworthiness Standards, which ensure that aircraft conform to requirements, and Aircraft Manual Digital Formats, which are used to streamline maintenance processes.
Aircraft Maintenance Documents
- Illustrated parts catalogues show the location and part numbers of items installed on an aircraft, but are not considered acceptable data for maintenance and repair by the FAA.
- Overhaul manuals contain information about the repair and rebuilding of components, and wiring manuals contain schematic diagrams to aid in electrical system troubleshooting.
- Structural repair manuals are used for repairing serious damage, and NAS Specifications provide a range of design and process standards, as well as material and parts specifications.
- MIL Specifications are developed and managed by the United States Military, and NSO Specifications are used to enhance the interoperability and operational effectiveness of alliance military forces.
