  1. NAS Architecturewww.nas-architecture.faa.gov/cats Steve Bradford FAA Architecture and Systems Engineering

  2. Seven Modernization Goals • Safety • Accessibility • Flexibility • Predictability • Capacity • Efficiency • Security

  3. NAS Architecture • “Living” representation of the FAA’s strategic plan for NAS modernization • Promotes FAA/industry collaboration and communication • Supports the FAA acquisition decision processes • Allows the system to be placed under control • Aids in the clarification of requirements and assessment of their impact on system design • Supports the FAA annual budget decision process

  4. AMS The NAS Architecture Logical View of the Architecture Blueprint for NAS Modernization NAS Architecture Version 4.0 Programmatic Schedule and Cost NAS Architecture Processes (Used to Create Logical & Technical Architecture Products ) Aviation Community Desires Technical View of the Architecture Government Policy & Laws NAS Requirements NAS RD Technical Details 4

  7. 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

  8. 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)

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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) • 2,864 approaches at 788 airports by 2010 (runways > 5,000’) • 4,450 approaches at 1,300 airports after 2010 (runways < 5,000’) • LAAS acquisition and fielding starts in FY 02 • Operational approval of Part 171 LAAS CAT I systems (non-fed) • Contract award for first 20 of 60 LAAS units • WAAS LNAV/VNAV test, evaluation and acceptance in FY 02 • WAAS IOC in 2003 for LNAV/VNAV • Additional geostationary satellite services decision is in review

  14. Surveillance Modernization • ARSR-4 - Complete FY1999 • ASR-11 • Funding through FY2008 for radars • SI and ASTERIX mods planned; SI complete 2010, ASTERIX complete 2008 • ASR-9 Service Life Extensions • ATCBI-6 • Funding to FY2005; complete 2004 • ASDE-3 Improvements • ASDE-X • Funding FY2005; complete 2005 • ADS-B - Enters as Pockets and NAS-wide starting in 2007; ~900 ADS-B ground stations

  15. Initial Set of ADS-B Functions… Safety Efficiency Surface movement with surveillance and navigation (ADS-B/CDTI/TIS-B) Surveillance in non-radar airspacewith radar-like separation (ADS-B or ADS-B/CDTI/TIS-B) Improved see and avoid capabilities (ADS-B/CDTI/TIS-B) Surface movement with surveillanceand navigation (ADS-B/CDTI/TIS-B) Surveillance in non-radar airspacewith radar-like separation (ADS-B orADS-B/CDTI/TIS-B) Oceanic ADS-A leading to 30/30 nmand 1,000 feet separation (ADS-A) Visual acquisition for approaches (ADS-B/CDTI/TIS-B) Candidate PRM replacement …with a path to greater capacity benefit through evaluationsunder Safe Flight 21 with emphasis on certification safety and use for maneuvering
