Prognostics as a Service Advisory Working Group Conducts First Meeting February 7th, 2018

The Prognostics as a Service (PaaS) Advisory Working Group held its first meeting on Wednesday, February 7th. The PaaS Advisory Working Group consists of 25 representatives from Urban Air Mobility (UAM) and Unmanned Aircraft Systems (UAS) technology companies, as well as academia interested in the as-a-service architecture for performing prognostics. The group will be advising the PaaS project on the challenges facing the PaaS architecture and will help identify opportunities for public-private partnership.

BACKGROUND: Prognostics is the prediction of system failures. The results of prognostics can be used to inform action to prevent failure, protect the safety of the vehicle, occupants, and environment. Prognostics can also be used to schedule system maintenance (predictive maintenance) for when maintenance is needed rather than by a pre-defined schedule, reducing maintenance costs.

The Prognostics-as-a-Service (PaaS) effort is a multi-center Convergent Aeronautics Solutions (CAS) incubation project. As part of the CAS Incubation effort, the CAS Team has identified the primary feasibility challenges to the PaaS architecture, created a prototype PaaS system, integrated the prototype into the Unmanned Traffic Management (UTM) architecture as a Supplemental Data Service Provider (SDSP), and matured the concept for CASTInG in May. The PaaS prototype enables aircraft to subscribe to a variety of prognostics services hosted on the cloud rather than hosting prognostics capabilities onboard, which requires significant computational power. Operators, autonomous systems, maintainers, air traffic control, and other stakeholders can then access the results with a Representational State Transfer (REST) Applied User Interface (API), using the information to protect the safety and efficiency of the vehicle and the airspace. If PaaS is selected in May, it will then begin an 18-month feasibility study.
