Phoenix, AZ – June 25, 2025. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it will join LDRA in a webinar on best practices for developing modular software for airborne systems. The free 60-minute webinar, hosted by Avionics International, will feature presentations by Gary Gilliland, Vice President of Marketing at DDC-I, and Stephen DiCamillo, Technical Marketing and Business Development Manager at LDRA. The webinar will be moderated by John Persinos, Editor-in-Chief Aircraft Value News, and streamed live on Wednesday June 25 at 12:00 PM EST.

“This webinar is a must see for avionics developers who want to develop modular, reuseable, certifiable software,” said Gary Gilliland, Vice President of Marketing at DDC-I. “We look forward to highlighting the challenges of developing safe and secure modular software components, as well as sharing best practices for software development and verification that facilitate compliance with appropriate functional safety and security standards.”
Designing systems which are highly adaptable and interoperable is particularly important in industries like aerospace and defense because of the need to incorporate rapidly evolving technology into platforms with a long service life. As a result, aerospace and defense organizations are embracing – and in some cases mandating – a Modular Open Systems Approach (MOSA). A MOSA emphasizes modularity, interoperability, and the use of open standards, fostering an environment where components from diverse sources can work together seamlessly.
Open architecture standards such as the Open Group FACE® (Future Airborne Capability Environment) Technical Standard, ARINC 653, and DO-297 promote modularity, reusability, and interoperability in software systems. These standards enable developers to create adaptable components that can be integrated across multiple platforms, reducing duplication and fostering flexibility.
While a MOSA offers significant benefits, it also presents unique challenges. Safety and security are especially important given the requirements for component modularity and portability, where components may be widely re-used across many systems. Given the rapid pace of technological innovation and understanding that most of this innovation is realized through software, it’s imperative that MOSA-aligned software components comply with appropriate functional safety and security standards.
In this webinar, DDC-I’s Gary Gilliland will explore some of the challenges for developing safe and secure modular software components. Gary will also discuss best practices for software development and verification that facilitate compliance with appropriate functional safety and security standards. To illustrate the best practices, Gary will show how DDC-I’s Deos™ RTOS and OpenArbor® IDE, together with the LDRA tool suite®, provide developers and QA engineers with the tools they need to develop safe and secure modular software.
About Deos
Deos™ is a safety-critical real-time operating system. First certified to DO-178 DAL A in 1998, Deos combines DO-178C Design Assurance Level A (DAL-A) artifacts with FACE® Technical Standard support that encompasses the Safety Base and Safety Extended Profiles for the Operating System Segment (OSS). The Safety Profiles features hard real-time response, time, and space partitioning, and both ARINC-653 and POSIX interfaces.
SafeMC™ technology extends Deos’ advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multi-core performance without compromising safety-critical task response and guaranteed execution time. SafeMC employs a bounded multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling, and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multi-core systems. These features enable avionics systems developers to address issues that could impact the safety, performance and integrity of a software airborne system executing on MCP, as specified by the FAA and EASA in A(M)C 20-193.
