Do software tests DO-178C?

DO-178C is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems. More recently, it has also become the de facto approach for the use of software in military avionics systems worldwide.

DO-178B documents?

What is DO-178B/ED-12B? The purpose of this document is to provide guidelines for the production of software for airborne systems and equipment that performs its intended function with a level of confidence in safety that complies with airworthiness requirements.

What does 178B Guideline specify?

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.

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

DO-178C addressed DO-178B’s known errors and inconsistencies. For example, DO-178C has addressed the errata of DO-178B and has removed inconsistencies between the different tables of DO-178B Annex A.

DO-178C high level requirements?

DO-178C (section 6) requires that: The high–level software requirements are correctly and completely formed from the system requirements….Other verification activities specifically listed include:

  • Walk-throughs.
  • Various static and dynamic analyses.
  • Code and document inspections.
  • Module level testing.
  • Integration testing.

What are the objectives of DO-178B?

The DO-178 standards requires that all airborne software is assigned a Design Assurance Level (DAL) according to the effects of a failure condition in the system….DO-178C Table A.5 Verification if Outputs of Software Coding & Integration Processes.

The objective should be satisfied with independence SI

What is DO 178B quality assurance?

DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems.

DO-178B testing guidelines?

DO-178C Table A.6 Testing Outputs of Integration Process

  • Executable Object code complies with high level requirements.
  • Executable Object Code is robust with high-level requirements.
  • Executable Object code complies with low level requirements.
  • Executable Object code complies with low level requirements.

What is design assurance level?

Design Assurance Level A (DAL-A) is the highest level of design assurance that can be applied to airborne software and is applied when failure or malfunction of the software could contribute to a catastrophic failure of the aircraft.

What is dal a certification?

DAL A describes flight electronics hardware whose failure or malfunction could cause a catastrophic, hazardous, or severe condition that would result in the deaths of everyone aboard the aircraft.
