What are the objectives of DO-178B?

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.

Key
The objective should be satisfied with independence SI

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.

DO-178B control categories?

non-independent assessment of compliance with DO-178B requirements. There are two control processes under which data can be classified: – Control Category 1 (CC1) and – Control Category 2 (CC2). CC2 is a subset of CC1 requirements and is less stringent in terms of software life cycle data management.

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 levels with examples?

What is DO-178B?

Level Failure Condition Example
B Hazardous/Severe-Majore Fuel management
C Major Pilot/ATC communication
D Minor Flight data recorder
E (Not relevant) Entertainment system

DO-178B Level A coverage?

According to the required level, different documents as well as quality proofs have to be provided. The different DO-178B-levels are defined according to the possible consequences of a software error: Catastrophic (level A), hazardous-severe (level B), major (level C), minor (level D) or no-effect (level E).

Does 178B have structural coverage?

DO-178B provides different criticality levels that must be achieved by any test software. Requirement-based testing (RBT) is one of the structural coverage techniques. RBT is used to achieve structural coverage testing by combination of requirement-based testing outcomes and their coverage analysis.

What is CC1 and CC2 in DO-178B?

CC1 is analagous to controlled documents in ISO 9001, and CC2 is analagous to quality records (evidence of work done) in ISO 9001.

Do data items parameters 178C?

This objective is now explicitly listed in DO-178C, Annex A, Table A-7, Objective 9: “Verification of additional code, that cannot be traced to Source Code, is achieved.” Parameter Data Item Files – Provides separate information that influences the behavior of an executable object code (without changing it).

DO-178B vs DO-254?

While DO-178 is the standard that defines the software planning, development, verification, quality assurance and configuration management process, DO-254 focuses on avionics hardware components and how designers must comply with certain safety specifications.

Does code 178B cover?

The “DO-178B” standard defines five levels of software safety risk. According to the safety risk of the code under test, the “DO-178B” standard defines different levels of code coverage that you must achieve during testing .

DO-178B levels have criticality?

The different DO-178B-levels are defined according to the possible consequences of a software error: Catastrophic (level A), hazardous-severe (level B), major (level C), minor (level D) or no-effect (level E).

DO-178B Design Assurance Level?

Therefore, DO-178B central theme is design assurance and verification after the prerequisite safety requirements have been established. The number of objectives to be satisfied (eventually with independence) is determined by the software level A-E.
