    BackgroundTraditional Airspace Design in the U.S.

    Purpose: Reconfigure route and sector geometry to

    enhance the safe and expeditious flow of air traffic

    Methodology: Airspace Management Handbook Airspace design teams Management and union leadership

    Features: Local expertise

    Robust design Subjective

    Stakeholder Involvement Political buy-in Analysis Paralysis

    Thorough Mature design Cost and configuration management

    Clean Sheet Airspace Design ProcessOverview

    Purpose: Make Conduct Airspace Study phase of

    the Airspace Management Handbookmore efficient

    Methodology:1. Traffic and Airspace Environment

    2. Airspace Partitioning

    3. Workability Evaluation

    4. Sector Audit and Remediation

    Features: Balanced and benchmarked complexity

    Best practices of airspace design

    Unconstrained by current boundaries

    Objective

    Repeatable

    Transparent

    Efficient

    Clean Sheet Airspace Design ProcessStep 2: Airspace Partitioning

    Purpose: Determine number, size

    and orientation of partitions

    Tool: airspacePartitioner

    Features: Complexity benchmarking

    Recursive k-means clustering

    Boundary smoothing

    Can partition around non-negotiable regions (e.g., SUA)

    Traffic Demand Profiles

    Partition region airspace with airspacePartitioner

    Airspace Partitioning

    Partitions with equal & benchmarked complexity

    Clean Sheet Airspace Design ProcessStep 3: Workability Assessment

    Purpose: Determine where configuration of

    flows and boundaries are incompatible with ATC services

    Tool: airspaceAnalyzer

    Features: Fast-time simulation ATC modeled as linear program

    Aircraft to aircraft separation Aircraft to airspace separation MIT spacing Return to course

    Records effort needed to service traffic flows

    Traffic Demand Profiles

    Partitions with equal & benchmarked complexity

    Identify problem partitions using airspaceAnalyzer

    Clean Sheet Airspace Design ProcessStep 4: Sector Audit and Remediation

    Purpose: Identify and rectify specific

    airspace design problems

    Tool: sectorEvaluator

    Features: Knowledge-based system

    GIS implementation

    Computes key airspace design characteristics and compares against best practices

    Indicates design improvements

    Airspace requiring boundary analysis

    Refine partition boundaries using sectorEvaluator

    Sector Audit

    ConclusionsLessons Learned

    Possible to capture and apply Principles of Airspace Design Objective Repeatable Transparent

    Process is non-trivial Efficient, but not a push button answer Refinement during implementation Human-centered design with computer assistance

    Particularly good for a regional airspace projects crossing facility boundaries Unbiased Provides a design to which

    stakeholders can react Focuses discussion on technical

    (rather than political) issues
