System Wide Safety Project Team Introduces New Framework for Managing Uncertainty

Dr. Matteo Corbetta and other members of the Discovery & Systems Health’s Diagnostics and Prognostics group have developed a framework for uncertainty representation, handling, and management. This framework is designed to accommodate different sources of uncertainty, such as inputs, models, measurements, and computing methods, in the computation of In-Time Aviation Safety Management System (IASMS) service outputs and metrics.

BACKGROUND: For more than three years, researchers have been developing a set of Services, Functions, and Capabilities (SFCs) to support the IASMS. Computation of these SFCs creates an opportunity to identify and quantify uncertainty for assessing risks for Unmanned Aerial Systems (UAS) in the National Airspace System (NAS) and subsequently make recommendations for mitigation. Uncertainty Management and Uncertainty Quantification (UM/UQ) has been identified as a key element for future airspace automation and could reduce required safety envelopes to enable more efficient and complex operations. The developed UM/UQ framework has been expanded and applied to wind uncertainty, positioning system errors, and uncertainties associated with Unmanned Aerial Vehicle (UAV) electric powertrains. This generalized framework can also be utilized for future Urban Air Mobility (UAM) vehicles and operations.
