The document discusses COTS FACE solutions from RTI and Wind River that can help address challenges in developing airborne systems. It describes how the FACE initiative uses standardized interfaces and layered architectures to enable software reuse and reduce costs. RTI provides a Transport Services Segment that uses DDS for loose coupling between applications. Wind River offers FACE-aligned operating systems like VxWorks 653 that achieve safety certifications. Together these COTS solutions form a partner stack that delivers FACE-compliant capabilities to warfighters faster and at lower cost.

1. COTS FACE Solutions
RTI and Wind River

2.  DoD Airborne systems are typically developed for
a unique set of requirements by a single vendor
– Long lead times
– Limited reuse of software
– Barriers to innovation / competition
Why the FACE initiative?
The Future Airborne Capability Environment (FACE) initiative is an approach
designed as a response
to the DoD aviation community’s challenges
 Existing DoD Acquisition structure does not facilitate software reuse well
 Open Architecture (OA) standards insufficient to enable software reuse
 Platform PMs are not funded to assume cost or schedule risk of multi-
platform requirements
