  1. Information Technology and Air Traffic Management George L. Donohue George Mason University NASA TGIR Conference 22 May, 2002 George Mason University Transportation Lab

  2. Technology • Major Advances over Last 20 Years with Potential to Impact ATM • Small Computers and Reliable Software • Aircraft Flight Management Systems • Universal Timing Accuracy to 3 nano seconds • GPS State Vectors for every Aircraft • Data Base Management Systems and the Internet • ETMS and Weather Data Collection and Dissemination thru FAA CDM System George Mason University

  3. Technology Could Enable • Complete Knowledge of Aircraft 4-D State Vector • Trajectory Based Flight Management and Required Time of Arrival Capability to < 30 Seconds • Aircraft Based Separation Assurance • Dissemination of Common Weather Prediction and Aircraft State Vector Information to All Flight Planers and Decisions Makers over the Internet • Optimum Use of the Air Transportation Network • Development of Small Unattended Airport Flight Separation Assurance System • Better Utilization of Nation’s Runway Infrastructure George Mason University

  4. Technology Has Not Provided • Sharing Information Between Aircraft for Conflict Detection and Collision Avoidance • No Agreement on Policy • No Agreement on Wireless Data Links • Ability to Deal with Weather Prediction Uncertainty over a 3-6 Hour Period of Time • Inability to Accurately Forecast Convective Weather • Inability to make Flight Planning Decisions in an Inherently Uncertain Environment • Minimum Aircraft Spacing, Required Time of Arrival Airport Efficiency • Imprecise Arrival Slot Controls Policy • Static Wake Vortex Separation George Mason University

  5. Capacity vs. Safety ? Safety Lost Capacity George Mason University

  6. Research Required • Airport Arrival Slot Allocations for Maximum Efficient Use of Runways • A New RW Slot Auction Market Exchange System Needs to be Developed • Ability to us ~90% of Maximum Safe Capacity with ~10% Uncertainty due to Weather and Equipment • Improved Decision Aids need Development • Transfer of Separation Assurance to Aircraft under Mixed Equipage Conditions • ADS-B Data Links Decision and new ATC Paradigm Needs to be Developed and DEMONSTRATED • Removal of Wake Vortex Static Safety Buffers • Dynamic WV Separation System needs to be Developed • Stochastic Modeling & Optimization of Traffic Management • New Models need to be Developed to Facilitate Designs of Above George Mason University
