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

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
