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.

SOFTWARE CONSIDERATIONS IN AIRBORNE SYSTEMS AND EQUIPMENT CERTIFICATION

Applications and Case Studies pp Cite as. The ideal of correct software has always been the goal of research in the field of Information Technologies. For the next years scientific communities hope for a great challenge: a complete strategy in software programming and software engineering supported by a range of analysis tools to design, develop, integrate, verify and maintain software applications with mathematical rigor. In this challenge formal methods shall play a key role. The adoption of these methodologies should be placed in the proper software engineering framework according to the software domain. In the avionic domain safety-critical software has to accomplish Federal Aviation Regulations by DOC or DOA means of compliance giving evidence that software implements its intended functions and does not perform unintended functions. The paper aims to provide an overview of the above mentioned standard.

ScopeThis document discusses those aspects of airworthiness certification that pertain to the production of software for airborne systems and equipment used on​.


Product Details

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. The evolution of the avionics industry that led eventually to DOB is included as part of the background behind the rationale of DOB.

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.

What is DO-278?

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. The failure conditions are categorized by their effects on the aircraft, crew, and passengers.

А потом мы позвоним директору. - Замечательно.  - Он даже застонал.  - Я позвоню Стратмору и попрошу прислать нам письменное подтверждение.

Может быть, Танкадо защитил его ровно настолько, чтобы вы на него наткнулись и сочли, что вам очень повезло. Это придает правдоподобность его электронной переписке. - Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.


Artifacts include all products of a certification development process and include Object-oriented software considerations in airborne systems and equipment.

Ничего не упустив. Беккер еще раз обвел глазами кучу вещей и нахмурился. Зачем АНБ вся эта рухлядь. Вернулся лейтенант с маленькой коробкой в руке, и Беккер начал складывать в нее вещи. Лейтенант дотронулся до ноги покойного. - Quien es.

Готов поспорить на любую сумму, что у партнера Танкадо будет иное мнение. Что бы ни произошло на самом деле, мы все равно выглядим виновными. Яд, фальсифицированные результаты вскрытия и так далее.  - Стратмор выдержал паузу.  - Какой была твоя первая реакция, когда я сообщил тебе о смерти Танкадо. Сьюзан нахмурилась.

Узнать, следит ли за ней Хейл, было невозможно. Нужно быстро пройти в кабинет Стратмора, но, конечно, не чересчур быстро: Хейл не должен ничего заподозрить. Она уже была готова распахнуть дверь, как вдруг до нее донеслись какие-то звуки. Это были голоса. Мужские голоса.

У него случился инфаркт. Я сам. Никакой крови. Никакой пули.

Сьюзан упрашивала его сказать, о чем в них говорилось, но он, кокетничая, отказывался. Тогда она взяла послание домой и всю ночь просидела под одеялом с карманным фонариком, пытаясь раскрыть секрет. Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи.
