Series Production Test should. To check out along the production and assembly phase, the functioning of the overall system as well as the functioning of the different components composing the system, as defined and built by design. To minimize production cost and time. Detect failures as soon as possible. Find the error. Test all functionalities of the system under test. Focus on time, Cost and Quality. Be only performed once aircraft is complete; on the assembly line stage B.

Regarding Workshop Test and Ground Equipment (WSTGE). Its scope is limited to the type of test and ground equipment used during complete A/C build, Final Assembly and Pre-Flight testing. Only Off-The-Shelf instruments are considered WSTGE. Test software is also considered as WSTGE. Test software is not considered as WSTGE. The normal assembly tooling (masters, gauges, fixtures, jigs, templates, robotics and related sw) are not considered as WSTGE. Two main branches should be considered - Servicing Equipment - Protection - Handling and access - Installation/removal - Test equipment - Off the shelf -Tailored.

Description of how to use a capability in Operational context and support environments. Communicates a story, written in jargon free language, for people with a wide range of technical backgrounds. Bridges the gap between the user ìs operational needs and visions and the System Developer ìs technical specifications. Conops addresses the Who, What, When, Where, Why and How for the system in general terms. It is useful to achieve mission success and avoid mission failure. It is the output in the stakeholders requirements elicitation. It is the input in the requirements analysis. It is normally graphically depicted for better understanding.

Kepner Tregoe Analysis (KTA) is used in trade-offs to justify the selection of candidates. Involve all the levels needed of the Vee to avoid repeating the same decision in the future. Decisions and their rationale are recorded to support future decision-making. A decision taken by an expert is always the right one. It is a good practice to document main project decisions to support future decision making and reuse.

Which of the following activities is(are) repeated at each level of functional analysis / architectural design?. Establish SW requirements. Develop the System Engineering Plan.

The SEP identifies the perimeter of the project. The SEP identifies the budget. The SEP identifies the documents used as inputs for the project. The SEP identifies the system architecture. The SEP is the tool to provide initial confidence to the customer on the capabilities of the organization to perform the project. The SEP describes the outcome of the tailoring exercise of generic organization processes best practices and lessons learnt to a specific project (reuse of experience). The SEP describes the outcome of the tailoring exercise of generic organization processes best practices and lessons learnt to a specific project (reuse of experience).

Why Configuration Management shall be implemented?. To maintain control over requirements. To prevent changes. To enforce change impact evaluation. To manage the impact of the change in a project.

When Integration strategy shall be defined?. At the bottom of the V (implementation). When defining the CONOPS. At the left side of the V. At the final stages of the project. In parallel with physical architecture design. In parallel with integration execution. In the functional analysis/architectural design phase.

Which processes belong to the technical processes group in the INCOSE Handbook. Development. Stake Holder Requirements definition. Requirements analysis. Architectural Design. Implementation Process. Integration Process. Verification Process. Transition Process. Validation Process.

When are logical architectures defined?. When SW development starts. Only if SysML notation is used. In the Functional Analysis/ Architectural Design phase. At each design level of a developing system. Before the requirements analysis phase. At the left side of the V.

Measurement process is used to. Estimate progress and calculate earned value. Estimate progress and the risk during development. Evaluate the size of the SW to be developed.

Which one(s) of the following statements apply to SAE ARP 4754?. Is used as a mean of compliance with safety requirements of systems. Defines DAL concept. Gives Certification considerations for highly Integrated or Complex Systems. Establishes the rigor and discipline needed in performing the supporting processes depending on the DAL. Defines the development assurance activities as: Safety Assessment, Validation, Verification & Configuration Management.

Validation is performed to. Demonstrate fitness to purpose of implemented systems. Agree on a budget when the project starts. Check the completeness and correctness of requirements. Ensure the final product will satisfy the requirements and user needs. Ensure the right product is being built. Prove compliance with the user satisfaction.

Regarding a modification after any certified aircraft becomes In Service. Only major modification affecting the Type Design shall de documented with a Service Bulletin. Issued to notify modifications, substitution of parts, special inspections/checks, reduction of existing life limits, establishment of first time life limits and conversion from one engine model to another, applicable on in service aircraf.

In the context of requirements engineering, which of the following sentences are true?. The system requirements are the foundation of the system. Design is what has to be done. Requirements engineering is the discipline concerned with understanding and communicating the externally imposed conditions on a proposed system. Requirements engineering acts as the bridge between the real world needs of users, customers, and other constituencies affected by a system, and the capabilities and opportunities afforded by the technologies. Requirements need to identify all the stakeholders. Requirements need to identify how and where the system will be used. Errors in requirements are very expensive. Early decisions save money. Changes in requirements are difficult to evaluate and track. Requirement must be SMART (Specific, Measurable, Achievable, Relevant and Traceable).

Which of the following are attributes of good requirements?. Clear - there shall be only one semantic interpretation. Consistent - one requirement shall not conflict with another. Verifiable - it shall be possible to verify that the solution meets the requirements. Implementation specific - includes how to aspects of design. SMART (Specific, Measurable, Achievable, Relevant and Traceable). Identify all the stakeholders. Avoids ambiguity (non-specific, possibility of different interpretations,lack of measurable criteria). Be autonomous. Contains more than one action verb. Avoid the use subjective language, with terms like user-friendly, easy-to-use and simple.

What kind of requirement is: the system shall be operational > 90% of the time?. Reliability. Maintainability. Durability. Functional. Non-Functional. Availability. Operational.

After Entry Into Service of an aircraft, who is the ultimate responsible for the safety of the operation?. EASA if operates in Europe and FAA if operates in USA. The local Airworthiness Authority (i.e. DGA in France, INTA in Spain, COA in Australia, etc.). The Customer (i.e. the owner of the aircraft). The aircraft manufacturer (i.e. Airbus, Boeing, Embraer, etc.). The Type Certificate holder. The organization in charge of the maintenance of the aircraft. The operator.

Any aircraft modification after release to the Operator shall be documented: Only in case of mayor modifications. In all modifications (minor and major).

In regard to Quality of requirements, the CCC acronym stands for: Correctness, Compatibility, Completeness. Correctness, Consistency, Completeness. Compatibility, Controllability, Completeness.
