5 Principles of MOSA

Dave Walsh, VP of Engineering, Parry Labs, explained the  5 principles of MOSA at “Quad A”, April 2023. The combination of the market advocacy and push from the US Army around MOSA, coupled with the pioneering work from a series of like-minded ecosystem companies means that this activity is gathering momentum. There is strong advocacy in market forums from the US Army about the “why” behind MOSA and there are announcements about systems that are MOSA compliant, including the RAIDER X and this ground platform from  L3Harris.

At Lynx, we see the support of standards for mission critical systems as being just the start. That is because APIs don’t define system behavior and timing. Read this piece by our CTO, Will Keegan, about more of our thoughts here.

Aviation Mission Computing Environment 

The Program Executive office (PEO) of the US Army is facing the challenge of modular and incremental deployment of software capabilities. The PEO Aviation (AVN) Enterprise has a platform entitled, “Aviation Mission Computing Environment” (AMCE) and is developing its Component Specification Model (CSM). The AMCE CSM consists of configurable processing, Software Operating Environment (SOE), and software loading requirements.

At the 79th Annual Forum of the Vertical Flight Society’s 79th (May 2023), a paper proposed definitions for software modules, operating system properties and key technologies for two distinct SOEs:

-  A mission system SOE

-  A safety critical SOE intended to address the Army Aviation Airworthiness Release (AWR) 

This was a collaborative paper developed by companies that includes Collins Aerospace, JHNA, Lynx, Parry Labs, RTI and US Army PEO.

The paper is being distributed by the Vertical Flight Society. If you have issues tracking it down via that path, feel free to contact us here.
