Building Avionics Systems for the Future

Today, the defense industry is strategically focused on modernizing systems. Noteworthy next-generation programs such as Joint All Domain Command and Control (JADC2) and Future Vertical Lift (FVL) are deploying complex digital capabilities at a break-neck time-to-field. These programs also come at a time when increased focus on cost and supply chain risk are driving innovative strategies across the industry.

RTI Connext TSS supports the evolution to the future battlespace by fulfilling the mandate of the Modular Open Systems Approach (MOSA). Connext TSS makes it easy for component developers and systems integrators to accelerate Future Airborne Capability Environment (FACE™) application component development and integration.

First-of-Its-Kind Connectivity for Safety-Critical Avionics Systems

Connext TSS has achieved two major industry firsts in Avionics. It is the first Transport Services Segment (TSS) to receive conformance certification to the FACE Technical Standard, Edition 3.1, and it is the first TSS available with RTCA DO-178C Design Assurance Level (DAL) A safety certification evidence. Combined with RTI Connext Cert, Connext TSS is uniquely able to deliver a reliable connectivity solution for modular, open, and safety-critical avionics systems that can help lower program risk.

Commercial Avionics

RTI Connext provides field-proven connectivity for mission-critical Urban Air Mobility (UAM) and eVTOL programs. It provides a path to commercial RTCA DO-178C and EUROCAE ED-12C DAL A certification, and runs on top of commercial avionics software standards such as ARINC 653, ARINC 661, DDS and POSIX for rapid integration.


RTI technology and expertise are proven around the globe in avionics systems built for the future.


An expeditious path to both FACE and safety certification.


Achieving airworthiness while enabling rapid insertion of new capabilities into deployed systems.
