Ames Researchers Present Work at ATCA: Five Aviation Systems Division lead researchers presented their work and participated in panel discussions at the ATCA Conference in Atlantic City. Fundamental NASA research and expertise was presented in the areas of traffic flow management, separation assurance, dynamic airspace configuration, weather integration and human factors. The talks were all well-attended and well-received by the national ATC research and development community.

NGATS Functional Model: SLDAST researchers conducted a demonstration of the NGATS air traffic management functional model instantiated in Enterprise Architect. The functional model represents the functional requirements of a future air traffic system. It is used to analyze functional coverage of evolving NGATS Airspace technologies and to ensure interoperability across those technologies. Enterprise Architect is a fast and intuitive graphical unified modeling language (UML) design and business analysis tool. Instantiation of the NGATS functional model in Enterprise Architect provides a user-friendly interface to facilitate 1) definition and organization of the complex interrelationships of the NGATS Airspace Project technologies and 2) analysis to ensure interoperability as the NGATS Airspace technologies are integrated into future system-level air traffic designs to meet the expected demands on the National Airspace System.

Standing Pilot Restraint System for Lunar Lander Simulation on the Vertical Motion Simulator (VMS): It is anticipated that the future lunar lander vehicle will be flown by pilots in the standing position similar to the Apollo era. In anticipation of this lunar lander configuration a standing pilot restraint system has been designed and installed in the lunar lander simulator cab on the VMS. Approval by the Human Occupancy Review Board (HORB) for the restraint system to be used during motion simulations was given this week.

Space Shuttle Vehicle (SSV) Landing and Rollout Training Simulation: The SSV Landing and Rollout training simulation was completed successfully during the period of April 9-20, 2007. This was the first entry of two for 2007 and was well attended by 25 pilots, 16 mission specialists, and 1 flight director. The scope of work included various software and visual changes to the math models, the runways, and cockpit graphics. This was in support of the crew familiarization of the landing and rollout phase of the mission for both nominal and off-nominal conditions.

A congressional committee looking at the nation's science and technology capabilities called out the Virtual Airspace Simulation Technology (VAST) capabilities, along with others, for investigation. The Rand Corporation was contracted to perform the investigation. Last week Rand interviewed the VAST software development lead. She described the VAST distributed real-time simulation environment and how it is used to conduct advanced air traffic management research.
