What is the difference between DO-178B and DO-178C?

What is the difference between DO-178B and DO-178C?

Differentiating between DO-178b and DO-178c is all about detail. Statistically speaking, the more information you have, the more you understand a situation; with DO-178c, aviation software developers are able to know — with significantly less confusion — whether or not the software is safe and functional.

DO-178B certification avionics?

DO-178B is a software produced by Radio Technical Commission of Aeronautics Inc. (RTCA), used for guidance related to Equipment certification and software consideration in airborne systems. It is a corporate standard, acknowledged worldwide for regulating safety in the integration of aircraft systems software.

Does a 330 tool qualify?

DO-330 Tool Qualification Levels (TQL’s) 1 – 5 are described as are DO-330 Tool Qualification Criteria (TQC) 1 – 3. Software and hardware engineering tools are computer programs that help engineers create, analyze, verify, track, modify, produce or specify the application programs being developed.

What is data coupling and control coupling?

Data coupling – The dependence of a software component on data not exclusively under the control of that software component. Control coupling – The manner or degree by which one software component influences the execution of another software component.

What are the requirements for a 178B?

DO-178B Documentation Requirements The base set of required documentation and life cycle artifacts include: Plan for Software Aspects of Certification (PSAC) Software Quality Assurance Plan. Software Configuration Management Plan.

What is 260B?

ADS-B refers to this general technology whereas DO-260, DO-260A, and DO-260B refer to specific RTCA minimum operating performance standards (MOPS) for an ADS-B system. There are two commonly recognized types of Automatic Dependent Surveillance for aircraft applications.

What is do330?

DO-330 provides tool-specific guidance for building airborne and ground-based software. It may also be used by other domains such as automotive, space, systems, electronic hardware, aeronautical databases, and safety processes.

When to use do 178B instead of DO-178B certification?

While DO-178B was principally written to cover original, custom developed avionics software, there is recognition that previously developed software can be DO-178B certified. In many cases, particularly military avionics software, DO-178B Compliance is used instead of DO-178B certification.

What’s the difference between do 178B and DO178B gap analysis?

DO178B Gap Analysis is an evaluation of your current avionics software engineering process and artifacts as contrasted to those required by DO-178B. While DO-178B was principally written to cover original, custom developed avionics software, there is recognition that previously developed software can be DO-178B certified.

How is the D0 / 178B criticality level determined?

There are five D0/178B criticality levels, with DO-178B Level A being most critical and DO-178B Level E being least critical. The DO-178B criticality level is based upon the contribution of the associated software to potential failure conditions. DO-178B failure conditions are determined by the FAA system safety assessment process.

Where can I find a DO-178B compliance checklist?

Checklists are used to ascertain and track DO-178B compliance. DO-178B checklists are available from public domain information if you have the time to assemble it (no such checklist is really proprietary or trade-markable), or from private sources who have merely assembled public domain information; simply contact [email protected] for options.
