Joint CADOM-SESO Collaboration Meeting: On July 10, researchers from the Airspace Systems, Airportal Project's Coordinated Arrival and Departure Operations Management (CADOM) and the Safe and Efficient Surface Operations (SESO) Research Focus Areas (RFAs) met to discuss plans for collaborating on a CADOM milestone for an initial evaluation of integrated systems for optimizing automated surface operations and arrival/departure operations. Among issues discussed were objectives of the experiment, approach, concept of operations, selection of simulation platform, and scope of the experiment (e.g., single airport or metroplex). Because of the nature of the work, collaboration with the Airspace Super Density Operations (ASDO) RFA was also discussed. It was decided to write a test plan to address these issues and outline the strategies. Gary Lohr (Langley Research Center) was nominated to draft the test plan.

Airportal Project Briefed on Fast-time Airport Surface and Terminal Airspace Simulation: Researchers gave a presentation of the new ACES enhanced surface and terminal airspace modeling tools to the Airportal Project on July 30, 2008. The briefing was made to both Ames and Langley Research Centers via WebEx. The Airportal Project is hosting a series of briefings designed to introduce their research staff to various NASA tools and data sources and to discuss their application. The presentation focused on how surface and terminal airspace air traffic management concepts and technologies can be modeled with the new tools. These tools support modeling of the airport surface as a link/node graph, wherein traffic is managed in and between gates and runways along the graph. The simulation provides extension points for researchers to "plug-in" future air traffic management concepts, e.g. Metroplex, Closely Spaced Parallel Arrivals, Weather Avoidance, Integrated Terminal Airspace and Airport Surface Route Optimization, and current concepts. Models for over seventy different US airports have been built. These are viewable in Google Earth. A demo was shown of Dallas-Fort Worth Airport in a south flow configuration.

Ames Researchers Visit NASA Langley: Ames researchers visited NASA Langley Research Center to discuss systems analysis of air traffic management concepts. During the visit, key line and project managers met to plan milestones. A draft of proposed system analysis milestones through 2014 was compiled. In addition, the Ames and Langley researchers engaged in a technical interchange of ground and air-borne concepts for maintaining separation between aircraft. Finally, a model that predicts future flight schedules was presented.

NASA and the National Oceanic and Atmospheric Administration will collaborate to understand the effects of wind uncertainty on aircraft trajectory predictions: NASA-Ames and the NOAA-Earth Science Research Laboratory completed an agreement to study wind uncertainty effects on aircraft trajectory predictions. This study will support the Trajectory Prediction, Synthesis and Uncertainty Research Focus Area (RFA) of the Airspace Systems Program. Scientists at the Earth Science Research Laboratory will create and provide estimates of wind forecast uncertainty using the Rapid Update Cycle (RUC) model along with an algorithm to assess the accuracy of these error estimates. The model data will only provide the data necessary for trajectory prediction applications reducing the file size and improving the operational usability of these data. A real-time data feed of error information will also be provided along with archives of previous data. This model uses a 13km horizontal grid that covers the United States. The RUC model is used by Air Traffic Management tools and created by the Earth Systems Research Laboratory.
