Modeling and Simulation

Dynamic Airspace Routing Tool

DART is a weather-aware, runway-to-runway, superfast-time National Airspace System (NAS)/Air Traffic Management (ATM) simulation model.

DART can process a highly complex day-in-the-NAS scenario with 50,000 flights, major airports, their runways, weather-dependent runway relationships, departure/arrival procedures, hundreds of sectors, weather, reroutes, aircraft sequencing, spacing, delays, cancellations and a multitude of Traffic Management Initiatives (TMIs) in two minutes on a standard PC—i.e., many times faster than competing products, without sacrificing simulation accuracy. While other models pre-process sector and runway capacities as a stand-in for weather impact, DART evaluates the location and intensity of weather (forecast or actual) and, in addition to adjusting airspace and airport capacity, will create operationally realistic “pathfinding” for tactical weather avoidance. Significant effort is applied to ensure proper DART model validation vs. historical observations.

Key DART Features
  • Integrated system-wide airport, airspace, weather and TMI simulation;
  • Exceptional computational performance on a standard PC or laptop;
  • Surface weather, terminal and en-route convective weather; blended actual and forecast weather for reroutes; weather permeability/airspace capacity degradation;
  • Airport runway layouts, configurations and capacity (as may be weather-degraded) gate occupancy and gate availability;
  • Runway dependencies; user-definable runway selection and runway queue balancing rules; Airport departure and approach procedures (SIDs and STARs);
  • Departure and arrival sequencing and spacing taking into account wake vortex and radar separation and runway dependencies; facilitated through ground delays, speed control, path stretching (“trombones”) and simulated holding on approach;
  • Two-stage sequencing (arrival fix traffic load balancing and spacing, then airport runways); modeling convective weather impact on departure/arrival fixes (delays, traffic redirection);
  • TMIs (NAS Playbook and other reroute advisories, GDP, GS, AFP, MIT, SUA, LOA);
  • User-definable rules, risk and cost factors, aircraft equipage profiles (e.g., DataComm) and airport/airspace/facility equipage deployment options;
  • Visualization and animation with time step ranging from 15 minute to 1 second;
  • Abundant output on all aspects of NAS, facility, airport, air carrier, airway and individual flight operation, delays and cost factors.
