This article needs additional citations for verification. This objective-based nature of DOB allows a great deal of flexibility in regard to following different styles of software life cycle. This can be difficult the first time a company attempts to develop a civil avionics system under this standard, and has created a niche market for DOB training and consulting. All tools used for DOB development must be part of the certification process.

Jeppesen corrects these errors or inconsistencies whenever possible by modifying the state provided data. It is the software safety analyses 020a drive the system safety assessments that determine the DAL that drives the appropriate level of rigor in DOB. Documents maintained by the configuration management process:.

For 20a that must be satisfied with independence, the person verifying the item such as a requirement or source code may not be the person who authored the item and this separation must be clearly documented. The listing of current Jeppesen Modified Data is provided below. Typically used software development process:.

Traceability from system requirements to all source code or executable object code is typically required depending on software level. Requirements traceability is concerned with documenting the life 2000a a requirement. Please help improve this article by adding citations to reliable sources.

Jeppesen is required by regulatory agencies to report Jeppesen Modified Data to our end-users. Software can automate, assist or otherwise handle or help in the DOB processes.

It should be possible to trace back to the origin of each requirement and every change made to the requirement should therefore be documented in order to achieve traceability. What is a Data Definition Document? Unsourced material may be challenged and removed.

This page was last edited on 4 Decemberat All data modified by Jeppesen should be considered fit for aeronautical use. Analysis of all code and traceability from tests and results to all requirements is typically required depending on software level. The intention of DOB was not to be prescriptive.

These software safety tasks and artifacts are integral supporting parts of the process for hazard severity and DAL determination to be documented in system safety assessments SSA. A third party tool can be qualified as a verification tool, but development tools must have been developed following the DO process. Type 2 acceptance letters are intended to facilitate the operational approval process or approved maintenance program, and eliminate the operator?

Although technically a guideline, it was a de facto standard for developing avionics software systems until it was replaced in by DOC.

These activities are defined by the project planners as part of the Planning process. Safety attributes in ddo design and as implemented as functionality must receive additional mandatory system safety tasks to drive and show objective evidence of meeting explicit safety requirements.

This page is a one-stop access point to Jeppesen LOA information and documentation. Tools used to verify the code simulators, test execution tool, coverage tools, reporting tools, etc. Tools generating embedded code are qualified as development toolswith the same constraints as the embedded code. This process handles problem reports, changes and related activities.

When performing these services, the Type 2 LOA holder is responsible for the integrity of the data and how it functions in the compatible avionic system.

The configuration management process typically gtca archive and revision identification of:. Type 1 acceptance letters are based on generic data requirements agreed upon between the data supplier and the customer and are for data suppliers that are data service providers.

DOB alone is not intended to guarantee software safety aspects. The interface to the certification authority is also handled by the quality assurance process. The system safety assessments combined with methods such as SAE ARP A determine the after mitigation DAL and may allow reduction of the DOB software level objectives to be satisfied if redundancy, design safety features and other architectural forms of hazard mitigation are in requirements driven by the safety analyses.
