05.22.07 Division Highlights

Experimental Results Raise Performance Benchmarks of Automated Conflict Resolution Algorithm: Experimental results generated last week have raised the safety and efficiency performance benchmarks achieved by a NASA-developed automated conflict resolution algorithm. The experiments simulated Cleveland Center air traffic (the busiest en-route airspace in the National Airspace System) at traffic levels up to three times that of today. For example, the previous algorithm resolved 99.19% of the conflicts detected under a "3x" traffic scenario. In the latest results, the algorithm resolved 99.97% of the conflicts detected in the same traffic scenario. A thorough compilation of all results is underway. It must be noted that, by design, this and all prior simulations were deterministic, meaning that trajectory errors were zero. Future work will incorporate increasing levels of trajectory uncertainty, which is expected to produce lower, but more realistic, benchmarks.

NAS Weather Impacts Technical Interchange Meeting: A technical interchange meeting (TIM) was held on Thursday May 17, 2007 in Washington, DC to discuss traffic flow management weather related research currently being performed to meet the challenges of both the current and future air transportation systems. The meeting was attended by representatives from NASA, FAA, Metron Aviation, MITRE, and MIT-LL. Dr. Grabbe (NASA Ames) presented the results from several ongoing foundational research activities being performed at NASA that are designed to assess NAS system performance relative to the weather conditions; translate convective weather forecasts into capacity constraints; and to assess the network impacts of convective weather on the current and future air transportation system. Although several research organizations were noted to be pursuing regression-type analyses to correlate observed delays with actual or forecasted weather patterns, NASA's weather translation was found to be unique and very well-received.

ATM Research Visualization Software Support Contract Signed: The Air Force Research Laboratory (AFRL) in Rome, NY signed a contract with Aerospace Computing, Inc. (ACI) in Mountain View, CA to provide on-site software development support at NASA Ames Research Center. The AFRL is working with NASA under the Memorandum of Agreement (MOA) for JView Visualization Support for Next-Generation Air Transportation System (NGATS). JView is a Java-based graphics library that the AFRL develops for a wide variety of visualization purposes. Under this new contract, ACI will work with AFRL researchers to develop JView-based applications for visualizing and processing data from the National Airspace System (NAS) and from simulations of the NAS incorporating future demand levels and NGATS technologies.

Ames Named Center of Excellence for Spacecraft Handling Qualities: Ames Research Center has been designated the "Center of Excellence" for handling qualities of piloted spacecraft. The primary task is to develop a Handling Qualities Standard for Piloted Spacecraft for AFRL. At the encouragement of AA Scott "Doc" Horowitz, the Vertical Motion Simulator (VMS) facility has been performing preliminary, human-in-the-loop, lunar lander simulations for the past year and a half. As a result of this work, "Doc" has expanded the task to include all piloted spacecraft, called out the VMS as the "primary test bed for lunar landing and Mars landing tests," and assigned Ames to lead the effort. In addition to lander vehicles, test plans will include rendezvous and docking operations for CEV/ISS, and LSAM/CEV. The project being planned will be a multi-Center, multi-facility effort that will serve Constellation through all phases of design, testing, and training.

Ames/Air Force Weather Agency Collaboration: Ames ATM/weather integration researchers are establishing contact with personnel in the Air Force Weather Agency (AFWA) located at Offutt Air Force Base, NE. to see if we can collaborate with them to improve the use of weather information for our ATM research. One of their personnel is detailed to the Naval Postgraduate School in Monterey which may make a collaboration easier.

DFW Terminal Area Radio Telecast System Operational: The DFW Terminal Area Radio Telecast System (TARTS) and TowerCam are back in operation after being removed for renovation work. TARTS is a NASA research system that provides streaming audio of Dallas/Fort Worth area pilot and controller communications. The TowerCam allows NASA users to have complete pan/tilt/zoom control over the camera to observe surface operations. Both of these research systems can be used to collect information in support of surface research and are restricted to NASA researchers.
