Increasing Capabilities


Nas architecture nas architecture faa cats

Current Communications

  • Separate networks for voice and data; separate operations and administrative networks; mix of owned and leased; old technology

    • Inefficient and costly

    • Limits NAS modernization and growth

  • Voice switch technology 10-20 years old with growing supportability problems; many FAA-unique interfaces

    • Complicates transition to digital network

  • Approximately 40,000 analog radios with growing supportability problems

    • Inefficient use of overcrowded spectrum


Nas architecture nas architecture faa cats

Communications Highlights

  • Modern ground telecommunications infrastructure

    • Integrated digital network for voice, data, and video

    • Different classes of service to meet operations and administrative user needs

    • Improved network monitor, control and usage data

  • Next generation air-ground communications

    • Digital radios for voice and data communications (continue to operate UHF radios for DOD users)


Nas architecture nas architecture faa cats

Communications Summary

  • Migrate to all-digital communications to take advantage of newer, lower-cost technology and services and provide seamless communications for NAS users

  • Integrate voice, data and video networks for greater efficiency, better management, and lower cost

  • Migrate to telecommunications industry protocols and standards to simplify interfaces and reduce cost

  • Transition to digital radios for better spectrum utilization

Current Data Link

  • Limited Data Link Capability

    • Available through a Commercial Service Provider

      • ACARS (analog system)

  • Domestic

    • 57 Busiest Airports in the Terminal/Tower domains

      • Two sets of messages: Predeparture Clearance and Weather Information

    • Detroit Airport - (Prototype)

      • One message: Taxi Clearance


Nas architecture nas architecture faa cats

Current Data Link (concl.)

  • Oceanic

    • Limited Controller Pilot Data Link Communications (CPDLC) for aircraft equipped with the Future Air Navigation System (FANS)

    • Available at multi-sectors in Oakland Center

    • Service Provider

  • Other Data Link Services - Different Stages

    • Traffic Information Service (TIS) provides situational awareness information via Mode-S

      • Service available at approximately 90 terminal Mode-S sites

    • Initial Flight Information Service (FIS) will provide weather, NOTAM, and SUA data

Navigation Transition

  • Current navigation aid (NAVAID) assets continuethrough transition with DOD reliance on TACAN

  • Navigation and Landing Highlights

    • SATNAV and RNAV

    • Augmentation of GPS necessary

  • Evolution of Navigation goes beyond just navigation and landing

    • ADS-B

    • Communications Timing

    • Moving Maps

Public Use Approaches

AVN Development Efforts and Plans (Safer Skies)

  • 12,600 instrument approaches exist

  • 3,009 GPS non-precision approaches (LNAV only)

    • 2,427 published

  • 529 LNA/VNAV approaches developed

  • 56 published since October 2000

  • Next Steps2,528 approaches at 576 airports by 2006 (Part 139 airports)
