Sign up for both, the DOC and Supplements courses, to take advantage of special rates. John Angermayer is an experienced Lead Multi-Disciplinary Systems Development and Software Engineer with 37 years of experience in software development….

The objectives include: Developing and providing the data for development of educational material; Providing the rationale behind the guidance for people new to the commercial certification environment; and, Clarification of the intent and application of DOB. The derivation of the software approval guidelines from the Federal Aviation Regulations FARs to DOB is discussed to clarify its relationship to the government regulations. An explanation of the Designated Engineering Representative DER system is also provided along with a discussion of the safety process to describe the environment in which DOB is used.

DOC Training Crash Course provides the knowledge required to reduce DOC risks and costs, while also enhancing the quality of the software during avionics development. During this intensive hands-on training, participants will learn the best practices for real-life software development and how to stay away from common DOC errors. The DOC, which is Software Considerations in Airborne Systems and Equipment Certification, is the main international standard for commercial avionics software development. DOC gives suggestions to produce effective airborne systems and equipment software. Agreement with the objectives of DOC is the key tools to meet airworthiness requirements and obtain approval of software used in civil aviation products.

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. Although technically a guideline, it was a de facto standard for developing avionics software systems until it was replaced in by DOC. The FAA applies DOB as the document it uses for guidance to determine if the software will perform reliably in an airborne environment, [1] when specified by the Technical Standard Order TSO for which certification is sought. The failure conditions are categorized by their effects on the aircraft, crew, and passengers. DOB alone is not intended to guarantee software safety aspects. Safety attributes in the design and implemented as functionality, must receive additional mandatory system safety tasks to drive and show objective evidence of meeting explicit safety requirements. Typically IEEE STD Software Safety Plans are allocated and software safety analyses tasks are accomplished in sequential steps requirements analysis, top level design analysis, detailed design analysis, code level analysis, test analysis and change analysis.

It became available for sale and use in January The FAA approved AC C [4] on 19 Jul , making DOC a recognized "acceptable means, but not the only means, for showing compliance with the applicable airworthiness regulations for the software aspects of airborne systems and equipment certification. Other concerns included the meaning of verification in a model-based development paradigm and considerations for replacing some or all software testing activities with model simulation or formal methods. Overall, DOC keeps most of the DOB text, which has raised concerns that issues with DOB, such as the ambiguity about the concept of low-level requirements, may not be fully resolved. All work is collected and coordinated via a web-site that is a collaborative work management mechanism.

Где-то там, на летном поле, в одном из трех частных ангаров севильского аэропорта стоит Лирджет-60, готовый доставить его домой. Пилот сказал вполне определенно: У меня приказ оставаться здесь до вашего возвращения. Трудно даже поверить, подумал Беккер, что после всех выпавших на его долю злоключений он вернулся туда, откуда начал поиски. Чего же он ждет.

Я не сказал ему про спутницу.  - Взмахом руки Клушар величественно отверг вопрос Беккера.  - Они не преступницы - глупо было бы искать их, как обычных жуликов. Беккер все еще не мог прийти в себя от всего, что услышал. - Может, там был кто-нибудь .

Парк был пуст.

Неужели ему предстояло погибнуть по той же причине. Человек неумолимо приближался по крутой дорожке. Вокруг Беккера не было ничего, кроме стен. По сторонам, правда, находились железные ворота, но звать на помощь уже поздно.

Беккер попросил дать ему картонную коробку, и лейтенант отправился за. Был субботний вечер, и севильский морг не работал. Молодой лейтенант пустил туда Беккера по распоряжению севильской гвардии - похоже, у этого приезжего американца имелись влиятельные друзья. Беккер осмотрел одежду. Среди вещей были паспорт, бумажник и очки, засунутые кем-то в один из ботинков. Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек.
