This whitepaper explains the seven principles of development that can be applied to the development of Avionics Systems and Equipment. These principles can, and should, be applied to engineering activities of any discipline – including Systems (ARP 4754A), Software (DO-178C) and Hardware (DO-254). In thinking about the Principles of Development we should consider three dimensions of development and how each of the principles affects that dimension:
1. The Process - The process dimension consists of the definition of the process, the execution of the process, and evidence, or data, left behind by the execution of the process.
2. The Product - The product dimension consists of all the elements of the product; requirements, design, implementation, verification, etc.
3. The Management - The management dimension consists of planning (or scheduling), organization, communication, and risks.
This DO-178C whitepaper aims to explain exactly what Data Coupling and Control Coupling (DCCC) are and identify what the DO-178C Certification concern is that is behind the objective. In clarifying what the real issue is, this whitepaper will identify where in the development lifecycle the issue should be considered, what activities should be performed in order to mitigate the concern and therefore achieve the objective.
This DO-178C technical paper will dive into the details of:
- What is Data Coupling and Control Coupling and why?
- Defining Data Flow and Control Flow (where and how).
- Verifying Data Coupling and Control Coupling (Optimized methods and examples)
- Analysis of Data Coupling and Control Coupling (relating to Requirements Based Tests)
Since 2014, ConsuNova's private and public trainings have been praised for up-to-date content, delivery style and trainers' knowledge providing the most Optimized and Fluent coverage of DO-178C, DO-254, ARP 4754A and ARP 4761 standards. As of 2020, with expanded needs for remote learning, ConsuNova has opened its modularized avionics training to the public with regular schedules.
In an effort to help ease these hurdles, Visure Solutions, Inc., an award-winning requirements ALM platform company, has partnered with San Diego, Calif.-based ConsuNova, a leading global provider of certification, compliance engineering services and solutions for safety-critical systems to the aerospace and defense industries.
ConsuNova has taken another step forward in response to high market demands by introducing ConsuNova EU. Lead by Martin Beeby, ConsuNova's Head of Advanced Avionics Systems and ConsuNova EU Managing Director, he aims to build on existing capabilities to provide expert local support within Europe and enhancing the global potential of the company.
DO-178C Training and ARP 4754A/4761 Training locations and dates in 2019 added by ConsuNova to meet surging demand. Expanded training schedule in response to market demand for practical instruction and focused topics such as "Optimized path to DO-178C Compliance" – ConsuNova adds locations and dates for the United States and Europe.
ConsuNova, Inc. releases Version 7 of their DO-178C Templates and Checklists with a promise of higher efficiency and DAL targeted models/modules for clients. Use of industry proven templates and checklists has long been considered a cost effective solution for any safety-critical systems development. Complementing the V7 checklists is the ConsuNova DO-178C Upgraded Process Templates. Now more than before, the templates are slimmer yet more targeted and customizable with added notes to differentiate DO-178C Design Assurances (DALs). Careful and consistent terms are used to quickly enable the clients customize each DO-178C process to their targeted DAL. A semi-automated spreadsheet alongtheside of a user-manual will assist the user to create DO-178C compliance table mapping planned Data Items Output to the required DO-178C Objectives for targeted DAL.

At UTC Aerospace Systems' request, ConsuNova developed a new approach for the company to provide its engineers with DO-178C Training virtually, in small segments over the span of several weeks. In this way, the AEE was able to replace its traditional in-person, instructor-led training with a more flexible solution to meet the needs of its global audience, while still maintaining the quality of instruction. By embracing the Academy's latest distance learning technologies, ConsuNova will contribute to significantly raising awareness, knowledge and understanding of how to meet key, potentially costly DO-178C Guidelines and their associated requirements.

ConsuNova continually refines its proprietary DO-254 and DO-178C Gap Analysis techniques, DO-178C/DO-254 Templates and Checklists. Backed by the strongest FAA DER team, avionics experts, and IT Platform, ConsuNova is joining ELECTRA IC to exclusively bring world-class and trusted solutions to the Turkish market.
A key mission of both organizations is to provide high-quality, efficient solutions, and use cutting-edge technology to achieve this. Having identified this common mission, ConsuNova and Rapita Systems engaged in a collaboration agreement in February 2016. Following from the results of this cooperation, including joint provision of DO-178C/DO-254 compliance workshops, expansion of the partnership is a natural evolution. By working more closely together, ConsuNova and Rapita aim to provide comprehensive solutions to aerospace and defense customers throughout the DO-178C/DO-254 project lifecycle.

The understanding and identification of FPGA/CEH component robustness is described as the ability of the FPGA/CEH to tolerate or respond to abnormal operating conditions. In practice, this description is somewhat open-ended. This paper establishes a reasonable boundary or limit for defining the abnormal operating conditions and how to account for them.
