Joint NASA and FAA Surface Research Transition Team meeting: On September 23 and 24, the third Surface Research Transition Team (RTT) meeting was held at the Joint Planning and Development Office (JPDO) Office in Washington, DC. The meeting was attended by representatives from the FAA, MIT-Lincoln Lab, MITRE, and NASA. The team agreed to embrace integration of arrivals and departures with surface traffic management based on guidance from the joint NASA/FAA RTT Coordinating Committee co-chairs. As a result, the group will now be known as the Integrated Arrival/Departure/Surface (IADS) RTT. This change in research focus addresses one of the important gaps identified in the JPDO's April 2008 cross-agency gap analysis exercise. In addition, by expanding beyond a narrow focus on surface traffic management, this team is now able to engage with Airspace System Program research focus areas such as SESO, CADOM and ASDO. On the FAA side, the expanded scope is expected to involve the System Operations service unit. The team continued writing the mid-term surface operational concept document. The document describes the intended tools and procedures for surface domain for implementation in 2018. NASA presented an initial Integrated Arrival/Departure/Surface Research Roadmap featuring Airportal and Airspace project research elements and the North Texas Field Site Testbed that will enable integrated system level evaluations. Other presentations included the JPDO Gap Analysis, details on the FAA's near-term Concept of Use for Surface Trajectory-Based Operations, an overview of Concept of Use and Concept of Operations documents within JPDO and the FAA and an FAA briefing on Surveillance Broadcast Services. The next meeting is planned for January 13 and 14 at NASA Ames Research Center. Agenda items include final revisions to the Mid-Term Surface Traffic Management Concept of Operations, discussion of NASA's initial IADS Research Roadmap and initial work on an IADS Concept of Operations.

Completed infrastructure for two-way communication between Surface Management System and the Airspace Traffic Generator: The infrastructure development for two-way communication between the Surface Management System (SMS) and the Airspace Traffic Generator (ATG) has been successfully accomplished. This is a critical achievement in the development of the real-time simulation environment for airport surface automation evaluation. This initial phase of development consists of two focus areas: the first is developing the two-way communication between the ATG and SMS software and the second is building a first-come-first-served scheduler that utilizes the re-designed SMS software's new plug-in architecture. Upon receiving flight plans from ATG, SMS develops a fixed taxi route and schedule for individual departing aircraft from aircraft spots to assigned runways, packages this information in a time-based taxi clearance format, and sends the clearance to ATG. ATG parses the clearance and moves the aircraft forward along the cleared taxi route while attempting to meet required times of arrival at check points. Kinematically feasible aircraft tracks are sent back to SMS. Further validation of the scheduler and performance testing will be performed and consistency of adaptations between the two systems will be examined as a next step.

Sept 9, 2008. AFM, SLDAST and the NextGen Airspace Project's Chief Scientist, Richard Barhydt met with JPDO's SMAD group, led by Yuri Gawkdiak: To discuss 1) how NASA's Airspace Concepts Evaluation System (ACES) can be used to support SMAD's assessment needs and to 2) discuss NASA plans to develop common demand sets (to support scenarios) and system-level metrics and assumptions. The objective of the ACES discussion was to ensure alignment of JPDO-SMAD and NASA needs, and to provide information to SMAD of current and planned NASA ACES capabilities, including the enhanced ACES capability to represent terminal and surface NextGen technologies at higher fidelities. During the common demand set, metrics and assumptions portion of the meeting, the SMAD group expressed great interest in developing a common "baseline" (scenarios, metrics, assumptions) that can be used by multiple groups (i.e. FAA, JPDO, multiple NASA projects) to ensure comparison of system-wide benefits across multiple concepts/technology options. A workshop was proposed to initiate a broader discussion amongst interested stakeholders to develop such a "baseline".
