UAS LVC Demonstration for the NASA Advisory Council
December 12, 2014

On December 4, 2014, the NASA Unmanned Aircraft Systems Integration into the National Airspace System (UAS-NAS) Project hosted members of the Aeronautics Committee of the NASA Advisory Council (NAC) at Ames Research Center's SimLabs Distributed Simulation Research Laboratory. NAC members in attendance included Committee Chair and former FAA Administrator, Ms. Marion Blakey, and Committee Vice-Chair, Mr. John Borghese. UAS-NAS team members representing the Human Systems Integration (HSI), Separation Assurance/Sense and Avoid Interoperability (SSI), and Integrated Test and Evaluation subprojects provided overviews of the Project's research approach and test results to date as well as plans for future simulation and live testing that will ultimately inform FAA decision-making on airspace integration procedures and performance standards to enable UAS integration in the nation's air transportation system. Following an overview of the live, virtual, and constructive (LVC) distributed test environment that is used to conduct the Project's human-in-the-loop experiments, the NAC members viewed a demonstration of the test products developed by HSI and SSI using the LVC environment. The demonstration highlighted the distributed capabilities of the LVC environment including constructive background air traffic generated locally, a virtual UAS operated at Armstrong Flight Research Center, a Boeing 747 Level D full motion simulator operating at Ames, and the Air Force Research Lab's Vigilant Spirit Control Station (VSCS) providing the UAS test subject with a virtual ground control station. The VSCS display demonstrated how self-separation algorithms combined with advanced display features can utilize inputs from on-board sensors to provide the UAS pilot with information necessary to maintain safe separation from other aircraft.

FIAT-5 Data Collection Completed
December 12, 2014

Twenty participants, comprised of eleven pseudo-pilots and nine controller subjects, took part in the second and last human-in-the-loop (HITL) simulation and data collection for the Fully-Integrated ATD-1 Test (FIAT)-5 during December 2-9th, 2014. The objectives of the data collection were to complete the validation of the Terminal Sequencing and Spacing (TSS)-enhanced Time-Based Flow Management (TBFM) version 4.2.0, to refine the procedures for off-nominal events, to explore baseline performance (without TSS), and to demonstrate air traffic situations relevant to, and to reduce risk for, the Operational Integrated Assessment (OIA) and/or operational deployment. A total of 22 runs were conducted over six days. Questionnaires were administered after each run. The testing of the off-nominal events provided data on the operational limitations of TSS, and conditions when controllers found it infeasible to continue to use TSS advisories. These conditions included such severe off-nominal disruptions that the TSS schedule could not be reasonably achieved. Seven FAA representatives were also present to understand the TSS capabilities. The next phase of risk mitigation simulations are scheduled for January 2015. (POC: Kevin Witzberger )
