Operational Modeling Two models developed by Georgia Institute of Technology will be used to model the sequencing and spacing needed to perform the TAP procedures Tool for Analysis of Separation and Throughput (TASAT) A Monte Carlo simulation environment that has been developed to predict trajectory variations of aircraft conducting the approaches. A separation analysis methodology that has also been developed to determine target sequencing and spacing required at the intermediate metering point. En route Speed Change Optimization Relay Tool (ESCORT) Solves a speed optimization and sequencing problem for en route (or terminal area) aircraft in real time Minimizes the increase in fuel usage that may be necessary to achieve the necessary spacing to fly a TAP Fairly divides the fuel usage increase among the aircraft involved 9 9
Integrated System Capabilities TASAT/ESCORT Decision support tool to calculate speed commands, required times of arrival (RTA), proper spacing, and sequencing 3-dimensional profiles from boundaries of ARTCC to corner post and TAP procedure from corner post to runway threshold Weather information Wind Conditions are important due to affects of wind on trajectories Use both historic (for statistical probability of trajectory) and current information Aircraft Communications Addressing and Reporting System (ACARS) Surveillance System Must provide accurate and real time position data for RTA and speed calculation by TASAT/ESCORT, as well as monitoring progress to determine if new speed calculations are needed ETMS will be used because not all aircraft have ACARS and ADS-B would require an installation of new equipment on the aircraft 10 10
Integrated System Capabilities (cont) Navigation System GPS based technologies Satellite Based Augmentation System (SBAS) and Ground Based Augmentation System (GBAS) will be used for the demonstration because it provides for more accurate vertical profiles for the TAP procedures Local Area Augmentation System (LAAS) or Wide Area Augmentation System (WAAS) will be used For equipped aircraft, WAAS will be used (use an LPV approach procedure similar to the TAP procedure created LAAS has been installed at Memphis; provides the information through a VHF data link (VDB) Some test aircraft will be fitted with test LAAS avionics from the FAA Technical Center Communication System Must be usable as a message communication system with several characteristics: real time, two-way data transmission user-to-user communication interoperability among users and organizations. Provide both air to ground and ground to ground communications. ATC VHF voice radio for the air ground communications and the telephone or internet for the ground to ground communications requirements. LAAS VBD to broadcast the approved complex TAP procedures to be used by the flight test aircraft. 11 11

Flight Demonstration Coordination Memphis Local Area Augmentation System (LAAS) is ready to broadcast the Terminal Area Path (TAP) procedures, The Multimode Receivers (MMR) must be modified to be able to: receive the TAP procedures; interface/integrate with the Flight Management System (FMS) and the Flight Data Recorder (FDR). For those aircraft without a MMR, GPS Wide Area Augmentation System (WAAS) receivers will be used. Installation and testing of the modified test MMR and to put the aircraft into a test mode. Each flight test aircraft must also have a verified and tested truthing system, operating properly. Coordinate with ATC controller union members to participate in this flight test and/or availability and use of ATC managers during the flight tests. Verify airspace availability during the flight tests for holding patterns and flight paths for the flight test aircraft to fly out and back on their designated TAP and en route procedures. ARTCC and TRACON have simulated and approved the TAP and en route procedures for the flight tests 17 17
