Airspace System
National Aeronautics and Space Administration
  • Briefing to the IT Summit
  • John A. Cavolowsky

  • Airspace Systems Program
  • Aeronautics Research Mission Directorate
  • August, 2010

Background
  • Demand for aviation is expected to increase,
    creating the need for a system that
  • Provides two or three times capacity together
    with increased safety, security, efficiency and
    environmental capacity
  • Accommodates a range of vehicles including very
    large aircraft, very light jets, unmanned
    aircraft systems and space launches

National Airspace System (NAS)
  • On average, about 50,000 flights use NAS services
    each day
  • 14,500 air traffic controllers
  • 4,500 aviation safety inspectors, and
  • 5,800 technicians to operate and maintain
    services
  • More than 19,000 airports and 600 air traffic
    control facilities. In all, there are 41,000 NAS
    operational facilities
  • Over 71,000 pieces of equipment, ranging from
    radar systems to communication relay stations

NAS is a highly complex system
5
Air Transportation in 2010
  • Since its inception, we have seen many
    improvements in the aviation system
  • Air traffic control procedures using radar
    separation and clearance-based operations for
    individual flights
  • Avionics including radios, flight management
    systems, traffic collision avoidance systems,
    data-links, etc.
  • Aircraft performance
  • Todays system is constrained
  • Capacity is limited by controller workload
  • Demand is managed to meet available capacity
  • Uncertainties in weather and flight trajectories
    are handled by personnel using operational
    judgment
  • And more

  • Schedule integrity under all weather conditions
  • Fuel efficient operations
  • Reduced costs
  • Predictability
  • Access
  • Preferred routes
  • Service Providers
  • Increased human-system productivity
  • Better and up-to-date information
  • National and community needs
  • Safety
  • Minimized environmental impact
  • Designed to accommodate future demand
  • Passengers
  • On time arrival and departure
  • Affordability and availability
  • Reliability and safety

Multiple needs of air transportation system
7
State-of-the-Art
  • Current air traffic management system is based on
    highly manual operations with limited support
    from decision support tools and automation
  • Role of air traffic management is to maintain
    safe, expeditious, and efficient flow of traffic
  • Strategic decisions (2-6 hours in advance,
    Command Center and Facility Traffic Management
    Unit)
  • Establish strategies for NAS and facility flow in
    and out of all airports and airspace in presence
    of weather and demand/capacity imbalance
  • Operations in airspace (En route and oceanic,
    rest of airspace)
  • Safely separate aircraft from each other and
    avoid severe weather
  • Provide most efficient operations
  • Operations near airport (Terminal, 30-50 miles
    from airport)
  • Separate aircraft and balance arrival/departure
    flows
  • Provide efficient routings for arrivals,
    departures, and overflights
  • Operations at each airport (Tower, 2-5 miles from
    airport and on surface)
  • Provide for safe and efficient movement of
    aircraft on taxiways and runways, and
    arrivals/departures near airport
  • Set runway configuration (arrival/departure
    allocation)
  • Current system is not well integrated nor scalable

8
Issues and Challenges Ahead
  • New types of vehicles and more unscheduled
    flights
  • Allocation of automation between cockpit and
    ground
  • Allocation of functions between automation and
    human operators
  • Graceful degradation of highly automated systems
    under off-nominal conditions
  • Insufficient information sharing between
    decision-makers
  • Leading to uncoordinated decision-making
  • Modeling failure and uncertainty
  • Dealing with weather uncertainty
  • Decision-making using probabilistic information
  • Development of fault tolerant systems integration
    for safety
  • Testing of new concepts in todays operations
  • Naming just a few

How will the nation address these challenges?
9
Achieving Future Air Transportation Capability
  • The Next Generation Air Transportation System
    vision requires a shift to trajectory-based
    operations using 4D trajectories, reduced
    separation in dense traffic, dynamic resource
    allocation to meet demand, and more
  • Significant research challenges must be met to
    mitigate airportal and airspace constraints to
    address the demand/capacity imbalance problem in
    a safe, equitable, and efficient manner

NASA transitions advanced technologies and
operational capabilities to implementing
entities. NASA has no operational
responsibilities or authority.

The Aeronautics Enterprise
  • As the science and application of aeronautics
    progressed, an interdependence developed among
    the aircraft, the air transportation system, and
    the people who use these systems, resulting in a
    multi-dimensional, highly integrated aeronautics
    enterprise.Treating the entire system as a whole
    is complex but necessary, and requires close
    coordination among multiple government
    departments and agencies as well as industry,
    academia, and other non-Federal stakeholders to
    ensure that the needs of all enterprise users are
    addressed.
