Aerospace, Military and Defence Safety-critical partitions versus mission-critical containers
platforms are underpinned with proven real-time operating system (RTOS) suppliers including, DDC-I, Green Hills Software, Lynx Software, Blackberry QNX, Sysgo, Wind River and others that can supply both commercial DO-178C DAL A safety certifi cation evidence and a wide range of security certifi cation solutions. Like enterprise containers, ARINC 653 partitions support application isolation, application workload portability, and separation of responsibility, and virtualize at the partition OS level, not at the computer hardware level, but do this statically, not dynamically, to meet strict
Honeywell Aerospace and Thales Aerospace that have been supplying ARINC 653 solutions for over two decades with the highest level of safety certifi cation evidence, RTCA DO- 178C Design Assurance Level (DAL) A. These
safety requirements. Due to the high cost and rigor associated with developing and deploying high multi-level safety and security certifi cation evidence for airworthiness, the ARINC 653 supply chain follows another open
industry standard, RTCA DO-297, that details the roles and responsibilities of each supplier in an ARINC 653 system, which reduces program development and operational costs and risks, driving effi ciency throughout the entire platform life cycle.
Unlike enterprise containers that use Kubernetes for orchestration, ARINC 653 partitions are statically defi ned and strictly managed by vendor-specifi c tools that integrate XML partition resource declarations into a fi le or binary that enables accelerated DO-178C certifi cation. Most of these tools have RTCA DO-330 tool qualifi cations that optimizes many of the requirements for achieving airworthiness. DO-330 requires the same software development rigor as airborne software (at the cost of $100-$500 per line of code), so Kubernetes, with over a million lines of code, is not a good candidate for DO-330 tool qualifi cation(1)
.
ARINC 653 is the open standard that is a fundamental component of the Open Group Future Airborne Capability Environment™ (FACE) Operating System Segment (OSS). Use of the FACE
standard is required in all US Army Future Vertical Lift (FVL) programs including Future Attack Reconnaissance Aircraft (FARA) and Future Long Range Assault Aircraft (FLRAA) aircraft. In addition, airborne applications may use a shared data model for unambiguous data representation, and be deployed using shared security domains to increase effi ciency and application management.
RTI, with its Connext product line coupled with its powerful partner ecosystem, runs in all these container and partition environments, from the connected edge to cloud environments. Connext is transport agnostic, OS/RTOS agnostic, and hardware agnostic – we do not constrain your design environment. We enable the use of the most powerful execution and deployment solutions found in the industry.
RTI is proud of the role we play in contributing to advanced solutions supporting data-centric applications for our global commercial and military avionics customer base.
