This task supports the development of the Airspace Super Density Operations (ASDO) FY2010 Milestone AS3.6.03 Simulations entitled “Evaluation of Single Airport Operations using Human-Centric Operations.” The software applications used for this simulation include Center/TRACON Automation System (CTAS), Stochastic Terminal Area Scheduling Simulation (STASS), Multi-Aircraft Control System (MACS) and Trajectory Route Analyzer/Constructor (TRAC). These applications are being developed as part of the Airspace Systems Program (ASP) at NASA Ames.
CTAS is a suite of air traffic management and air traffic control decision support tools that span the entire national airspace system from take off to touchdown. The CTAS tools benefit air traffic managers and air traffic controllers by reducing stress and workload, and they benefit airspace users by reducing delays, increasing safety, allowing environmentally-friendly operations and improving robustness in all-weather conditions. The CTAS tools most relevant to the ASDO AS3.6.03 simulation are the Traffic Management Advisor (TMA) and the En-Route/Descent Advisor (E/DA). These two tools provide assistance to en route and terminal air traffic controllers managing traffic flows into congested terminal areas.
STASS is a fast-time analysis tool used to model various terminal area scheduling algorithms under a wide range of traffic scenarios and demand levels. STASS randomly varies aircraft arrival times into the terminal airspace and then stochastically models the accuracy of those flights in meeting their scheduled arrival times at the meter fixes and runway thresholds. The results are used to investigate the trades of delay, throughput and controllability with arrival time uncertainty, in-trail separation buffers, and delay margin or time advance along the route of flight.
MACS is a human-in-the-loop simulation environment that emulates state-of-the-art air traffic controller displays for en route and terminal airspace. The en route displays replicate the Display
System Replacement (DSR) workstation and the terminal displays replicate the Standard Terminal Automation Replacement System (STARS) or Automated Radar Terminal System (ARTS) Color Displays (ACD). In addition to modeling the current day air traffic control environment, MACS is designed as a platform for rapid prototyping of new decision support tools and controller interface changes. It already incorporates a variety of advanced capabilities for aircraft scheduling, trajectory manipulations, conflict probing and airborne sequencing and spacing applications.
TRAC is a graphical design, simulation, and analysis tool designed to make the process of designing routes for simulations faster and more transparent by enabling routes to be graphically manipulated. TRAC can also host fast-time agent-based Monte Carlo simulations using a redesigned aircraft simulation module with advanced Flight Management System (FMS) functionality. TRAC can therefore be used to generate traffic scenarios, and examine the behavior of aircraft on newly designed routes subject to the interventions of air traffic controller agents. TRAC also facilitates data comparison between fast-time simulation data, human-in-the-loop simulation data from MACS, and recorded data from actual current-day operations.
This task will include the following areas of responsibility related to the simulation:
• Scenario development (e.g., traffic demand input files)
• Site adaptation development (e.g., airspace and procedure design)
• Hardware and software integration
• Configuration management of simulation software
• Human-in-the-loop simulation execution
• Archival of simulation products
• Data analysis of simulation results
• Migration of scheduling logic from STASS to CTAS
The primary success criterion for this task is the execution of the ASDO AS3.6.03 simulation by Q4 FY2010.
