FACE® TIM Paper: Lessons Learned Developing and Integrating MOSA DO-178 FACE Control Components

TES-i and AWESUM® are successfully “leading the charge toward Modular Open Systems Approach (MOSA)” by building Device Control utilizing a MOSA, DO-178C and the FACE® approach. This paper presents our lessons learned over the past years applying the FACE Technical Standard, Edition 3.1 to build and integrate FACE components that are airworthy and developed using Model Based System Engineering (MBSE) models to auto generate documents, code, and tests.
