It became available for sale and use in January The FAA approved AC C [4] on 19 Julmaking DOC a recognized "acceptable means, but not the only means, for showing compliance with the applicable airworthiness regulations for the software aspects of airborne systems and equipment certification. Other concerns included the meaning of verification in a model-based development paradigm and considerations for replacing some or all software testing activities with model simulation or formal methods.

Overall, DOC keeps most of the DOB text, which has raised concerns that issues with DOB, such as the ambiguity about the concept of low-level requirements, may not be fully resolved. All work is collected and coordinated via a web-site that is a collaborative work management mechanism. The failure conditions are categorized by their effects on the aircraft, crew, and passengers.

DOC alone is not intended to guarantee software safety aspects.

Safety attributes in the design and as implemented as functionality must receive additional mandatory system safety tasks to drive and show objective evidence of meeting explicit safety requirements. The certification authorities require and DOC specifies the correct Do-330 software tool qualification considerations when dating be established using these comprehensive analyses methods to establish the software level A-E.

The number of objectives to be satisfied some with independence is determined by the software level A-E. The phrase "with independence" refers to a separation of responsibilities where the objectivity of the verification and validation processes is ensured by virtue of their "independence" from the software development team.

For objectives 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. DO requires a documented connection called a trace between the certification artifacts.

A traceability analysis is then used to ensure that each requirement is fulfilled by the source code, that each requirement is tested, that each line of source code has a purpose is connected to a requirementand so forth.

Traceability ensures the system is complete.

The rigor and detail of the certification artifacts is related to the software level. The structure of the document remains largely the same from B to C. DOB was not completely consistent in the use of the terms Guidelines and Guidance within the text. The additional clarification fills a gap that a software developer may encounter when interpreting the document.
