A Complete Guide to
DO-178 (Software)
DO-178C (Update)
DO-254 (Hardware)
The first book on the most important safety certification documents (DO-178B and DO-254) for commercial and military avionics
Now with a 178 updat
by Vance Hilderman and Tony Baghai
The authors take you step-by-step through each milestone on the way to certification. They describe hundreds of examples, cases and actual experiences acquired while winning approvals for over 300 programs.
DO-178B and DO-254, they explain, are intentionally written to be vague.The documents contain considerations, not requirements----but you won't get certified without them. To reach that goal, the authors offer practical advice acquired over two decades of certifications now flying aboard every major airliner and numerous military projects. "We don't teach regulations," they say, "but how to think like the FAA."
They fill the book with anecdotes that show how many companies make false starts, waste time and break budgets. Each myth and misconception about DO-178B and DO-254 is dissected and debunked.. You'll also find the best way to get a project started (begin with the "big bang" or an evolutionary approach). There is even guidance on how to staff a project.
After traveling the certification route so often, the authors have strong opinions, and they don't hold them back. For example; when should you argue with your government auditor, how to deal with a DER (Designated Engineering Representative) and what are typical numbers for lines of code? Then there's story of how one little comma (,) in the wrong place cost $125 million on a trip to Mars. You'll get a chuckle over software that deteriorates into science projects, or dealing with engineers who become artists. There are suggestions on when to give your manager a raise.
There's advice on which tools to use and what to avoid, the merits of different programming languages, what the D in DO-178B should really mean, when planning can be too good, why some managers get it right the first time, some the second, some the third (and when it's too many times). There's the sad tale of a Very Light Jet manufacturer who ignored the authors' advice about unacceptable software in redundant systems. The FAA rejected it and the company lost $10 million.
This book is not a typical tutorial. Besides their software services, the authors are active trainers. Between them, they've taught DO-178B/DO-254 to more students than all other seminars combined. Their wisdom can provide valuable insights to bring your project to a successful conclusion.
