Departure Flow Management
DFM is a web-based capability that automates the
APREQ release process
  • How it works (high-level)
  • The ARTCC TMC creates FEAs using a TSD to define
    the flows they need to monitor
  • The ARTCC TMC enters restrictions on the flows
    using the DFM web application
  • DFM queries TFMS for the FEA flight list and
    entry times
  • DFM identifies all gaps in the restricted flow
    and presents a timeline for the TMC to monitor
  • When a pilot calls for taxi, the ATCT looks for
    the flight on their DFM web application
  • If the flight is restricted, DFM shows all of the
    available release times for the flight
  • The ATCT selects the desired release time
  • DFM assigns the flight to the first available
    release time at or after the desired time and
    sends this information to the ARTCC TMC
  • Current focus
  • Harden v1.4 of DFM prototype for field operations
  • Support long-term field evaluations at 3-6
    Centers beginning in March 2009

    performance of the NAS
  • For a given TFM enhancement, or investment, what
    effect would it have on NAS performance?
  • Current focus
  • Maintain metrics website and compute 2009 values
    for existing suite of metrics add new metrics as
    needed
  • Compile data for, and update periodically, a TFM
    Factbook illustrating the impact of TFM
    activities on civil aviation in the U.S.
  • Continue to develop passenger-based metrics to
    illustrate impact of TFM activities on passenger
    trip time
  • Interpret long-term trends and investigate days
    having extreme values for each metric
  • Research ways to align our metrics with NextGen
    Operational Improvements

White Papers
  • Surface Congestion Fuel Burn Reduction
  • Identify and analyze future concepts to reduce
    surface congestion and thereby reduce fuel burn.
    Examples include virtual queues,
    slow-roll/managed taxi speeds, etc
  • Dynamic Allocation of NAS Resources
  • "Dynamic Airspace Configuration is likely to be a
    key part of the future NAS. This project will
    explore operational concepts for partitioning
    portions of airspace for specialized temporary
    use to demonstrate what is achievable using
    todays tools. An example is to use existing
    FEA/FCA capabilities to define temporary
    exclusion zones around arrival routes as a means
    to monitor, schedule, and coordinate Continuous
    Descent Arrival (CDA) operations
  • Pre-day of Operations TFM concepts
  • Explore and evaluate concepts for conducting TFM
    activities before the day of operations using
    predominately airline schedule and/or historical
    data

26
White Papers
  • Environmental Modeling Analysis of TFM
    performance (fuel burn estimation)
  • Develop (using, e.g., POET-R and NASEIM) methods
    to compute fuel burn for individual flights.
    Conduct pilot study of impact on fuel burn of
    various TFM actions. First step toward having a
    fuel burn analysis capability that might be
    incorporated into decision support tools.
  • ESP Delay Estimation
  • Apply automation developed to support DFM to the
    ESP delay prediction problem, to assess the best
    approach to and potential value of automatically
    forecasting these delays in aggregate
  • Surface Data Usage
  • Continue the CE that was started under the TSDI
    project to develop concepts for increased use of
    surface surveillance data including better
    departure time predictions, improved awareness of
    surface operations, and greater insight into
    gridlock identification, prediction, and
    prevention

27
White Papers
  • NextGen of FSM slot assignment logic
  • Current FSM slot assignment algorithms date from
    the 1990s and only partially accomplished their
    goals of efficiency, equity, predictability and
    control. This effort will examine alternative
    approaches such as Lagrangian relaxation to
    rewrite FSM algorithms to be more flexible and
    better able to achieve TFM objectives
  • SUA Information Research
  • Develop concepts to increase the utilization of
    SUA for commercial aviation. One such idea is to
    adapt the SEVEN concept to the special case of
    SUA utilization to electronically communicate the
    requirements of the military for SUA and to
    quickly make use of the airspace when the
    military doesn't need it.
  • Additional AFP Capability Usage
  • AFPs were designed specifically as a replacement
    for GDPs in support of SWAP however, additional
    applications such as AFPs for Mexican MIT have
    also been adapted. This work will further
    explore and develop additional applications of
    AFPs to improve TFM.

28
White Papers
  • Departure Information Services
  • Continued CE on the concepts and functionality
    developed by the DFM workgroup including
    departure fix balancing and using DFM departure
    controls to increase constrained airspace
    throughput. New capabilities could potentially go
    into the current DFM prototype or the WP2 IDAC
    capability.
  • Airspace Capacity Estimation
  • One of the biggest challenges with AFPs or other
    airspace TMIs is knowing the capacity of the
    region of airspace when it is impacted by
    weather. This work will seek to apply to growing
    body of research into airspace capacity
    estimation to develop near-term decision support
    capabilities.
  • Airborne Delay Research
  • Apply existing algorithms for measuring where
    airborne delays occur to develop an Airspace
    Congestion Predictor (ACP) that would provides
    metrics for measuring existing airspace
    congestion, the capability to predict future
    airborne delays and congestion, and provide
    metrics for comparing candidate TFM strategies
