▌Airworthiness system construction
With its thorough understanding and rich experience of various safety-critical industry standards, Aiweixun uses its extensive network of domestic and foreign expert resources to help different customers such as mainframe manufacturers or aviation product providers to help them establish and improve airworthiness. Required R & D and airworthiness management system. including but not limited to:
Based on the mature IDEAL model in the industry, Aiweixun has provided airworthiness system construction services for domestic AVIC, CLP Group and other units to help them establish a basic airworthiness work framework and organizational assets.
▌Airworthiness project consulting
According to the design assurance level (DAU) of the customer's project, a full set of planning templates are provided, and in combination with the actual situation of the project, the customer is guided to complete the preparation of the plan document. At the same time, Aiweixun also provides a supporting plan document checklist to support the customer to complete the Review of plan documents.
For specific projects, provide customized solutions to help customers meet airworthiness requirements. Provide full life cycle support for system development, airborne software development, electronic hardware development, supplier control, etc., and solve key and difficult issues in the project (such as source code to executable code traceability, compiler verification, etc.) The implementation steps are roughly divided into:
According to the customer's existing foundation and the actual situation of the project, help the customer analyze and locate the processes and problems that need to be invested in consulting support in the project life cycle.
According to the situation of the preliminary demand analysis, comprehensive consideration is made from the two aspects of engineering technology and airworthiness review, and a complete consulting implementation plan is customized for the client. This plan can only be implemented after the client's review and confirmation.
According to customer needs and technical solutions, organize matching project teams to carry out project implementation. During the implementation process, it will maintain implementation communication with customers, comprehensive project management and quality monitoring to ensure the quality of consulting services.
Aiweixun has many airworthiness experts from domestic and foreign bureaus and DER backgrounds. They have rich experience in airworthiness review. They can find potential problems in airworthiness compliance and technology in advance and propose corresponding solutions to help customers. Successfully passed the airworthiness certification.
According to the DO-178B / C and DO-254 standards, and referring to the requirements of FAA Order 8110.49 and Order 8110.105, the SOI # 1 ~ SOI # 4 simulation review is carried out on the software and electronic hardware projects on the client, to help customers find airworthiness compliance at all stages in advance Sexual issues.
Participate in various airworthiness review activities on behalf of customers (including those for local authorities, host manufacturers, and suppliers), and provide on-site support, including helping customers prepare compliance data or review agenda arrangements, on-site responses Compliance issues, and solutions for non-conformance recommendations.
Answering all kinds of airworthiness certification questions raised by customers in a remote consultation-based manner, including but not limited to: supplier airworthiness document review, difficulties in the forensic process, preparation of question minutes and positions, etc.
Combine with DO-178C, DO-331 and other model-based development and verification (Model Based
Development and Verification (MBDV) relevant airworthiness standards
And many years of practice in system and software modeling, Avexun has summarized a set of requirements for airworthiness
The required MBDV practice specifications and supporting virtual project cases. On this basis, Aiweixun
Can conduct in-depth research and practical cooperation in MBDV with customers.
According to the airworthiness requirements of DO-178B / C and the solutions approved by the bureaus of various countries, the "safe subset" method is used to verify the specific compilation environment. By performing a complete test and tracking analysis of the source code object code within the scope of the "safe subset", the reference code that complies with the software coding standard verifies the accuracy and reliability of the compiler's behavior in a specific environment.
▌Airworthing project outsourcing
Aiweixun has a professional airborne software development team that can develop airborne software according to customer needs. It can use a combination of model-based development and traditional manual coding. The working specifications meet the requirements of the customer system and DO-178C, Requirements for airworthiness standards such as DO-331 are good at MBDV related modeling tools such as SCADE Suites, SCADE Display, Simulink, etc.
Aiweixun has a professional airborne software verification team, the main members are from COMAC, Rockwell Collins, Honeywell, Siemens and major domestic evaluation centers. Many of the onboard software provide software verification services that meet DO-178B Level A requirements.
Aiweixun can also provide a wealth of tool customization services according to customer needs and project conditions, and has the ability to develop customized tools based on .NET, JAVA and other mainstream technologies. At the same time, based on Aiweixun's rich experience in the high security industry, the tool customization service provided by Aiweixun can bring additional added value to customers, rather than merely informatizing customers' offline work.
