Avionics Architecture Team (AAT)

• In an effort to realize the benefits of a Modular Open Systems Approach (MOSA) to Open Architecture, the team currently supports and maintains the Future Airborne Capability Environment (FACETM) standard and the Hardware Open Systems Technologies (HOST) standards.

• The team supports aircraft platforms in defining potential OA solutions through Model Based Systems Engineering, identifying specific areas of strategic reuse, and defining the functional architecture to facilitate the implementation of these solutions.

• The FACETM initiative establishes a technical and business ecosystem to enable open software architectures, software portability and reuse, and ease of software integration efforts resulting in decreased costs and shortened fielding schedules. The FACE™ standard supports a modular approach to software design and development.

• FACE™ is gaining traction in current and future NAVAIR development plans, including the H-60 Flight Management Function Application, Next Generation Jammer, C-130T Avionics Obsolescence Upgrade, MQ-25, CH-53K Basic Cockpit Upgrade, F/A-18 Distributed Targeting Processor-Networked and the Tactical Combat Training System Increment II. FACE™ is also widely used in numerous U.S. Army platforms within PEO Aviation.

• The HOST standard specifies the intermediary interface definitions at the module level (circuit card or mezzanines). The model similarly applies to the proliferation of common or interoperable Single Board Computers (SBCs), chassis, and power supplies; and allows the interface definition to be shared with module suppliers so that a modular hardware element can be developed.

• Current focus has been on the HOST standard for Open VPX in the T-45 Mission Computer Alternative and F-35 Block IV Upgrade.  The HOST standard is also focused on PC/104 as the next smaller form factor used in the Resilient-Embedded GPS/INS (R-EGI).
