The basic electric installation storable assembly is. The wiring diagram as it contains all the relevant information to produce the harnesses. The basic electric installation storable assembly are the Harnesses. The harnesses made of wires, connectors, backshells, identification, protections, etc. Harnesses that is the electrical manufactured unit that collects the elements described in the WD (Wiring Diagram).

The harnesses are composed by: Always cables from a single wiring diagram, including its connectors. Cables from a wiring diagram, including its connectors. c. Cables from multiple wiring diagrams, including shared connectors between systems.

The wiringdiagrams…. Are based in Principle/circuit diagrams, but with simplified content. Contain cable types and gauges, equipment connectors and pin to pin details, but no break up connectors are included. It represents all the elements required to both manufacture and installation in the A/C ensuring its functioning and integration with the rest of the systems. It is performed by a Design installation team activity. It is aligned with Interface and Marry Up diagrams, if drawn per MC.

At the Preliminary Design Review (PDR). Requirement documents are frozen. System architecture schemes are frozen. Aerodynamic shape is frozen. The data for manufacturing released will start.

In relation to Data for Manufacturing, indicate which of the following statements are true. A welded element is a detail part as it is not possible to dismoun. The Engineering Change Note, or Document Change Note, describes in detail the changes and explains the reasons to do them. An installation drawing represents the instructions to install a set of parts, assemblies, equipment, standards, etc. The Dash Number is part of the Part Number and needs to evolve when the part changes physically. Starts with the CDR concept phase.

At the Preliminary Design Review (PDR). Requirement documents are frozen. System architecture schemes are frozen. The data for manufacturing released will start. Aerodynamic shape is frozen. Jig & Tools data frozen.

Regarding the Configuration Management Functions, indicate which of the following statements are true: The establishment of uniform access privileges for users is essential for data protection and dissemination. Product operational information is derived from the product definition information. Purposes of Configuration Verification and Audit are to ensure that the product design validate the integrity of the product configuration information and verify the consistency between a product and its configuration. The form and format of the planning documentation are critical for the Configuration Management process achievements. Verification & Audit. Identification. Change Management. Status Accounting. Planning and Management.

When Standard Change Process is applied: CCB1 cannot reject an Enterprise ChangeRequest. The effectivity information is fully managed through the change process. The impact assessments should be performed during creation phase. Difference between Standard Change Process and Fast Track Change Process.

Regarding Product Structure, indicate which of the following statements are true: Product Structure is not a condition of success of the concurrent engineering process. A View is the filtered and frozen (as a picture) product information from a given layer to describe a given state of the product. The product structure relationships are managed (established) with the change of modification number. Product Structure is organized in a network made of LAYERS.

The Declaration of Design and Performance document (DDP). Cannot be substituted by other official certification documents (TSO, FAR33, etc.). Contain the Statement of Compliance or the Deviation List with respect to the Specification. DDP is the document which assure that the equipment comply with the requested function.

In relation with Outsourcing Design activity, which of the following sentences are false. The supplier is always responsible in front of the authority. in an outsourced component, the design shall be always transferred. Statement of work is always required (exam 2014). Even with a design transferred, the stress analysis should never be transferred.

Indicate the true sentences: Equipment are standardized parts. DDP is the document which assure that the equipment comply with the requested function. Detail part with a heat treatment is, in fact, an assembly. The system EDR is equivalent to the SIRD plus the system equipment EIRD´s. Equipment has always the condition of identification by serial number. Functional Item Number (FIN) uniquely identifies performing a function in an aircraft system.

Which of the following requirements must be typically considered in a harness design?. Moisture protection/sealing, abrasion/ vibration protection and heat protection. Space and weight savings, high reliability and easy of replacement. Labelling of the harness at the both ends and additional labelling each x metros in case of long harnesses. Labelling of clipping points and type of attachment supports.

In order to avoid connectors unadverted cross connection during maintenance or assembly, some of the following means may be used (in order of preference within each sentence): First connector’s Key rotation and then rotation of inserts. First connector’s Key rotations, then rotation of inserts, and finally connector shell size change. First connector’s rotation of inserts and then key rotation.
