The Vertical Motion Simulator (VMS)

Control Allocation for Pilot-Induced Oscillation (CAPIO) Simulation on the Vertical Motion Simulator (VMS)
This pilot-in-the-loop simulation evaluated CAPIO's effectiveness in alleviating pilot-induced oscillations that occur when control surface actuators hit rate limits typically during aggressive maneuvering. The Cruise-Efficient Short Take-Off and Landing (CESTOL) mobility concept aircraft developed by Boeing Research and Technology (BR&T) for the Air Force Research Lab's Speed-Agile Concept Demonstrator (SACD) Program was used and the NASA-developed CAPIO controller was integrated with the SACD baseline flight control system. The system was evaluated using aggressive and precision maneuvers that were specifically designed to expose any Pilot Induced Oscillation (PIO) tendencies in the system in a controlled and repeatable manner. Seven experienced test pilots evaluated the system in a total of 647 data runs. The Principal Investigator for the study stated that, “The VMS staff support was excellent. Their dedication made this an outstanding experiment.” (POC: Steven Beard)

NASA presents research to American Airlines executives
NASA researchers met with American Airlines executives to discuss areas of possible collaboration. The June 29th meeting was held at the American Airlines Headquarters near the Dallas/Fort-Worth (DFW) Airport in Texas. The participants included leaders of various areas within American Airlines and a senior leader of the DFW airport. Personnel from NASA Headquarters, Ames and Langley represented NASA's Airspace Systems Program. The presentations included a wide range of topics that included the ADS-B Enabled Green Operations using Integrated Scheduling and Spacing (AEGIS) project, surface management research, tactical runway configuration management, aircraft-based conflict detection and resolution, dynamic weather routes/ground-based trajectory based operations, and weather integration and translation. The NASA's North Texas Field Site and its role in potential collaborations was also reviewed. Both NASA and American Airlines expressed interest in pursuing some of these projects and discussions are underway on how to best proceed to develop new collaborations. (POC: Tom Davis)

Another Successful EDA Simulation with FAA Controllers in the Loop
A human-in-the-loop simulation of the Efficient Descent Advisor (EDA) was successfully conducted the week of June 20, 2011 in the NASA Ames Crew-Vehicle Systems Research Facility. This was the sixth simulation carried out under the 3D-Path Arrival Management (3D-PAM) technology-transition effort. Participants included active-duty controllers from Denver Center representing the National Air Traffic Controllers Association. The simulation objectives were twofold: 1) evaluate the impact of an active, radar-side conflict probe on EDA operations and controller acceptance, and 2) demonstrate the ability of EDA to support mixed avionics equipage, meaning a large proportion of the arrival traffic featured less-advanced flight management systems, typical of regional jet aircraft, for example. Anecdotal feedback from the controller subjects indicated that the conflict probe was beneficial to EDA operations. A mixed-equipage arrival stream presented no observable issues or concerns. Detailed results are forthcoming. The simulation was well-attended by government and industry stakeholders, including representatives from the FAA, Boeing and MITRE. FAA attendees included the 3D-PAM project lead along with representatives from the En Route Automation Modernization (ERAM) and Time-Based Flow Management (TBFM) project offices interested in discussing field integration and deployment strategies. Of particular interest was how 3D-PAM/EDA might be leveraged to address the FAA's requirement for Ground-based Interval Management (GIM), slated for deployment in the 2014 timeframe.
