Collaborative Arrival Planning (CAP)

• Objective
• Improve the efficiency of air carrier operations
  and increase NAS flexibility.
• Components
• Information sharing between ATC and air carriers.
• Air carrier / ATC collaborative decision-support
  tools.

Information Sharing

• CAP displays a specialized, filtered repeater
  of the operational FAA CTAS TMA system at ZFW.
• CTAS information
• Accurate arrival time estimates
• Metering delays
• Arrival sequence
• Center/TRACON/Airport information
• Airport acceptance rate (AAR)
• Runway configuration
• ARTS runway assignments

Airline Operational Control

• CAP operating at American Airlines DFW System
  Operational Control Center since April, 1998

• Enables dispatchers to make better hold/go
  decisions during periods of extended airborne
  holding.
• Supports strategic fleet planning decisions.

6
Ramp Tower

• CAP operating at Delta Air Lines DFW Airport
  Coordination Center since August, 1999

• Enables better decisions whether or not to hold
  flights to make passenger connections.
• Allows more effective management of ground
  resources (e.g., gates, baggage-handling,
  catering, maintenance.)

CTAS Digital Data to Industry

• Digital data generated on NASA/FAA CTAS TMA
  system at ZFW.
• Sent to Volpe Center over dedicated T1 line.
• Volpe filters CTAS data.
• Digital data sent from Volpe to air carriers via
  CDMnet.

CTAS Digital Data to Industry

• Data will only be provided in digital format.
• NASA/FAA/Volpe will NOT provide new display
  tools.
• Air carriers will subscribe to Volpe for CTAS
  data.
• Socket connection similar to SMA digital data.
• Interface Control Document (ICD)
• Data format/content.
• HW/SW requirements for connection.
• FAA/Air Carrier MOA will govern use of digital
  CTAS data.
• Carriers must sign MOA to have access to digital
  CTAS data.
• Schedule
• CTAS digital data available Summer 00.
