developments follow guidelines defined by the ED/DOB document. This paper first reviews the activities traditionally performed in such developments. 27 Mar The best way to approach DOB is from the reverse of the document! Your But this is not a tutorial, right? The second most interesting. DO C tutorial is designed by TONEX to help you improve your overall DO- C is the modified and updated version of DOB/EDB (), which.

It does do-178bb reflect the official position of HCL. Tools used to verify the code simulators, test execution tool, coverage tools, reporting tools, etc. You need to know how to read it. Hi The stuff you’ve jotted makes good reading.

Typically used software development process:. 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.

Do you think, DOB may get outdated in that case. This objective-based nature of DOB allows a great deal of flexibility in regard to following different styles of software life cycle. I received a comment with an incorrect e-mail id I actually wanted to thank this person that indicated that the person has taken umbrage to the above post. Processes are described as abstract areas of work in DOB, and it is up to the planners of a real project to define and document the specifics of how a process will be carried out.

DOB, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems. What DOB attempts to do, and probably succeeds in doing, is to force you to consider and to precisely specify many things about your development effort that have little to do with coding, and much to do with project management and with software engineering. Processes are intended to support the objectives, according to the software level A through D—Level E was outside the purview of DOB.


This figure beautifully brings out the concept of Requirements-Based Testing.

birds introduction to DOB

This might involve negotiating a deal with a company that owns an aircraft of the necessary type and is eager to install your product on it. Retrieved from ” https: This page was last edited on 4 Decemberat tutoriao Inexpensive certification depends on tutoriaal documents not only saying the right things, but saying them in the right way, in the right order. That’s all to it. As indicated in the post, this is an “easy read” technique that I follow.

I recommend you visit do–178b In other words, if you are ignorant enough to be seeking illumination from the Birds Project, you shouldn’t be undertaking airborne projects that are large enough or critical enough to interest certification uttorial. Hi, according to these crosstalk articles DO stands for Document Order. Actually, there are a few non-DOB things you need to know before beginning software development. Can someone confirm this? 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.

Alternately, you may need to work with the aircraft manufacturer that holds the TC on that aircraft type, it thus it may be the aircraft manufacturer who opens the FAA project and receives do-1178b STC.

How to read DOB – the easy way – Aerospace Software

In this case, the practical consequence is often to pervert the spirit of DOB by expediently reducing its implementation to a question of deliverables. On a real project, the actual activities that will be done in the context of a process must be shown to support the objectives. All ro-178b used for DOB development must be part of the certification process. I admit to ignorance as to what happens in the case of a TSO: The “deliverables” are mainly documents, and successful certification ro-178b on these documents saying all the right things.


A Simple Phrase

Amitabh March 29, at Software can automate, assist or otherwise handle or help in the DOB processes. Somtime back I ketp on hearing that Module testing would be elimated for Airborne software.

Most importantly, each objective is cross-referred to a paragraph in the main text of the document. VDC Research notes that DOB has become “somewhat antiquated” in that it is not adapting well to the needs and preferences of today’s engineers. Subscribe to this blog’s feed. This can be difficult the futorial time a company attempts to develop a civil avionics system under this standard, and has tutodial a niche market for DOB training and consulting.

No, seriously, if you want do-178n read DOB the fun way, this is it. Once the DER has signed off, the product really is essentially “certified” for the holder of that form.

These software safety tasks and artifacts are integral supporting parts of the process for hazard severity and DAL determination to be documented in system safety assessments SSA. Do you tutoriial why? Notice we are still languishing at the end of the document!
