  1. The Impact of IT onAir Transportation Dr. Thomas A. Edwards Chief, Aviation Systems Division NASA Ames Research Center

  2. CTAS – The First Phase of Automation Descent planning region TMA plans sequence and landing time FAST advises for accurate spacing on final approach EDA advises conflict free fuel efficient descent Final approach planning region EDP advises conflict free departures Direct-To advises flight plan short-cut opportunities

  3. Automated Airspace Revolutionary Advancements Made Possible Through IT Air/ground Integration Improved Traffic Flow Free Flight DSTs Greater Automation/Precision of Information Leads to a More Deterministic System Automaticity (System wide optimization, separation assurance) System-Wide Optimization Inclusion of all Airports Improved System-Level Monitoring and Diagnostics Centralized Traffic Flow Management CNS Precision (Weather, System, Demand, Navigation, Surveillance)

  5. VMS FFC Training Centers Rotorcraft Operations Flight and Tower Simulators FAA Tech Center CVSRF ATC ATM and Human Factors Labs at CVSRF Space Operations High Density Airports Concept Validation Through System-Level Simulation Collaborative Tools for System Level Assessments Virtual Laboratories for Command and Control Future Air Transportation System Network/Architecture Links Facilities Seamless integration of national simulation facilities into a virtual validation environment enables rapid prototyping of future ATM concepts and high-fidelity, human-in-the-loop demonstrations

  6. Summary • We are in the midst of implementing the first level of automation in the aviation system • By leveraging advances in computing, networking, and CNS capabilities, far greater advances are possible • Implementing revolutionary systems will be made possible only through the use of state-of-the-art capabilities in system specification and high-fidelity simulation
