What is DO-178 and why is it important?
DO-178 has specific objectives based upon the criticality level of the software. Higher DAL’s must satisfy more DO-178 objectives than lower levels. After the software criticality level has been determined, you examine DO-178 to determine exactly which objectives must be satisfied for the software. Now you are ready for planning.
Who is the attendee of DO-248C and DO-178C?
RTCA DO-248C, Supporting Information for DO-178C and DO-278APlus attendee’s choice of: John Angermayer is an experienced Lead Multi-Disciplinary Systems Development and Software Engineer with 37 years of experience in software development… Mr. Kent Hollinger is a Principal Engineer at The MITRE Corporation.
Which comes first DO-178 planning or development?
As can be seen in the above figure: the DO-178 Planning process comes first, and when complete is followed by a larger DO-178 Development process. In the background the largest process, Correctness (Integral Processes: QA, CM, Verification, FAA Certification Liaison), is performed continuously.
What is a DO-178C Software Verification Plan?
SVP: the DO-178C Software Verification Plan defines the strategy to review, test, and analysis the corresponding software requirements and code. Each of the above DO-178C Plans typically requires 40-50 pages each.
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.
What does do stand for in DO-178?
• DER: Designated Engineering Representative. • DO: (RTCA) Document.
DO-178C is based on a fundamental framework for defining Development Assurance Levels. There are five different levels, each one relating to the gravity of what happens if the software fails, ranging from Level A (Catastrophic) to Level E (No effect on safety).
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.

Does 178C verify software?
DO-178C specifies that the software verification should be “requirements based”, as opposed to source code based. Requirements based tests will require that testers or developers build the input data to exercise the code that will satisfy the requirement.

Can you do 254 Dal C?
Simply stated, DO-254 is a requirements-driven process-oriented safety standard used on commercial electronics that go into aircraft. (Conceptually speaking, this standard applies to all electronics in anything that flies or could crash and pose a hazard to the public.)
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.
