Acknowledgement
  • The surface operational concept to be discussed
    was developed as an element of an Airportal
    Project Operational Concept by a team consisting
    of Jonathan Lee (Volpe), Jim Poage (JLP
    Performance Consulting), Gary Lohr (NASA Langley)
    and myself, under the leadership of Steve Green
    (NASA Ames).

5
A candidate concept for surface
  • Not a concept of operations
  • Airportal Project focused on key set of research
    issues
  • Scope constraints
  • Budget constraints
  • Concept is broad (initially)
  • Provide framework for Airportal
  • Means of communication with Airspace Project
    JPDO

6
A candidate concept for surface (continued)
  • Concept to evolve as project develops
  • Concept to generate issues for analysis
    simulation studies
  • Airportal Project studies will, in turn, generate
    revisions to concept
  • Greater levels of detail to be added as project
    evolves

7
Surface Concept Elements
  • Runway management
  • Taxi route planning
  • Surface super density operations
  • Surface weather environmental planning

8
Runway management
  • Optimized runway taxiway configurations change
  • Dynamic allocation of runways (for a given
    configuration)
  • More efficient departure sequences and schedules

9
Taxi route planning
  • Planning efficient routes under specific airport
    constraints
  • Minimize queuing provide clearances for longer
    taxi segments
  • Provide for equipage differences, user
    preferences fairness
  • Integrate ground movement in to surface traffic
    flow
  • Execute adhere to more precise taxi routes

10
Surface super density operations
  • Reduced runway incursions taxiway conflicts
  • Precision runway/taxi operations
  • Reduced runway occupancy time
  • Reduction of wake vortex impacts
  • Intersecting converging runways

11
Surface weather environmental planning
  • Weather
  • Environment

12
Additional surface issues
  • Human factors, a cross-cutting topic
  • Terminal surface integration
  • Airport redesign

13
Human factors challenges for surface operations
  • Greater levels of flexibility increased levels
    of automation
  • Human roles in coordination/negotiation processes
  • Display design for tower operations

14
ASDO Integration
  • Airspace Super Density Operations (ASDO)
    challenges
  • enabling precision trajectories in dense terminal
    airspace
  • robustness with respect to changing weather
    conditions
  • satisfying environmental constraints
  • Integration issues
  • dynamic scheduling of gaps to allow for runway
    crossings
  • ensuring tighter airborne spacing use of high
    speed taxiways results in acceptable rate for
    go-arounds
  • coordination of runway management with terminal
    operations
  • role of controllers in airborne/surface SDO
    integration

15
New/existing airport design leveragingadvanced
airport capacitytechnologies procedures
  • Concept requires flexibility maneuverability
  • Sequencing/scheduling of taxiway traffic
  • More precise pushback times
  • Resequencing to accommodate changes in runway
    operations
  • Airport redesign should consider these control
    elements their impact on capacity (when
    leveraging advanced technologies)
  • Staging areas
  • Added taxiways (including perimeter)
  • High speed taxi exits
  • Deicing facilities
