Software prototype is developed to display and compute airspace capacities using the Localized Aviation MOS Program (LAMP) weather forecast model in the Future ATM (Air Traffic Management) Concepts Evaluation Tool (FACET)
In August 2010, Mosaic ATM completed a briefing and software demonstration of work to translate and display LAMP data in FACET. LAMP is an operational forecast product developed by the National Weather Service's Meteorological Development Laboratory to provide objective long-range probabilistic forecasts of thunderstorms that can be used for airspace capacity estimates. This work is being conducted with funding from the American Recovery and Reinvestment Act (ARRA). All Mosaic ATM software is external to FACET and the display of weather data are accomplished using FACET's external software interface. Mosaic ATM plans to complete the infrastructure to support airspace capacity estimation models and will begin implementation of some models in the near future.

Direct-To Clearances Found to be Robust to Traffic Management Initiatives
Air traffic managers and airline operations personnel have in the past expressed concerns that automated "direct-to" clearances (route shortcuts) may routinely conflict with arrival traffic management initiatives, thus undercutting the benefit case for direct-to clearances. However, a study just completed finds that such conflicts are infrequent and the benefit case for direct-to clearances is robust. Using 13 days of recorded traffic data from Fort Worth Center in the presence of metering restrictions, ground delay programs and ground stop initiatives, only 14% of direct-to advisories had the potential to interact with traffic management initiatives. By withholding those advisories, the integrity of the traffic management initiatives was preserved, and the remaining direct-to advisories saved an average of 553 minutes of flying time per day -- 87% of the original benefit pool.
