The structure of the book follows the table of contents; unfortunately, the content of the chapters does not.
There is a great deal of repetition that was not checked. The book contradicts itself on the numbers, 20-40% for DO-178B cost, 25-40% level A-D [p140], 50% A-D [p40], cost metric table [p228], and quality/cost graph [p231]. I am not disputing the numbers, but I would expect the numbers to be consistent within the book, at least.
The errors in guidance are much harder to accept, because others may be using this book as a guide. Here are some examples:
1) "An operating system such as <commercial plug> can be certifiable, but tools, other components or board support package are not as they can only be verified when integrated with other software components." [p38] Unless the board support package can be partitioned from the operating system, which in general cannot be done, the board support package must have the same level of certification evidence as required by the operating system. .
2) In the discussion of independence, it is difficult to establish if the test/review is to be independent or the review of the coverage analysis [p143]. DO-178B is very clear on this in Table A7.
3) The explanation of Decision and MCDC coverage objectives is unnecessarily confusing.Read more ›
Not being a true expert in avionics software certification, I cannot judge the book's technical quality from this regard. However, I do know that DO-178B is a living standard, and that all civil avionics software (practically everywhere in the world) on commercial planes these days had to be written to conform to DO-178B in some way. There are rumors that the recently announced Boeing 787 delay was partially due to the headaches of this standard. But the 787 is certainly one of the most complex avionics systems to have been developed, so this is no surprise that the certification to DO-178B is pushing the envelope and hard to predict in terms of time.
I do know quite well the text of the DO-178B standard. By itself, it provides little practical knowledge, as it was written and maintained by a smallish group of people within the US civil aviations industry. The FAQ part of the DO-178B standard, known as DO-248B, is more useful, but is still hard to digest for those of us trying to get some insight about this arena.
That being said, this book is simple and to the point, and it helps you understand where are the important pitfalls in a DO-178B certification. It's full of practical information, and it's obvious that you're getting the authors' bias of 20+ years' experience in avionics software development.Read more ›
I found this book useful when discussing certification issues with my clients. It helps them to understnd and provides a 'dictionary' when addressing the processes to be followed. Everyone can learn something from this book and I highly recomend it to engineers and project managers involed in aircraft certification.
A much more enjoyable read then I had expected give the subject matter.
I only wish I would have had it 4 years ago when I started working with 178B as it would have saved me a lot of frustration and time.

The authors preach integrity and quality, but they haven't spent a nickel on editing their own book.
A terrible book on a very important subject.
Text appears to be unedited symposium notes. Poor flow, fractured construction, minimal effort extended to produce a quality product. Read morePublished on December 6, 2011 by ADT

Let me start by saying that if I thought I knew more than the authors did, I wouldn't have bought the book. I'm quite sure that the authors know DO-178B and DO-254 inside and out. Read morePublished on December 1, 2009 by F. family
