Areas of Practice: Air Traffic Management


GRA has been involved in examining how air traffic management services are provided worldwide. The firm has supported major modernization initiatives, including FAA’s Next Generation Air Transportation System, and also conducted the first study of a single air traffic system in Western Europe for the Association of European Airlines, which led to the SESAR initiative.

Other air traffic management engagements include:

  • Decades of cost allocation and reauthorization support for FAA, including model development and data management to analyze the impacts of potential changes to the FAA’s financing and governance structure
  • Comprehensive analysis of shifting the provision of FAA air traffic control services to a government corporation. GRA assisted an inter-agency Executive Oversight Committee and supported task forces in budget and finance, governance, personnel and procurement.
  • FAA New York City airports slot auction design
  • Airspace studies and business case development for air traffic management service providers in Bermuda, Bahamas, Indonesia, and Panama

To support much of the work noted above, GRA developed and maintains the FAA’s integrated Air Traffic Organization activity measurement and cost analysis system, the Air Traffic Services Business Model (ATSBM). The model tracks all costs and activity at the air traffic service delivery point level (i.e., individual towers and centers); it also estimates the costs of maintaining individual National Airspace System facilities, such as radar, communications, and navigation and landing systems.
