  1. Evolving Concepts in CNS/ATM Mr. John McGraw, FAA 20th Annual JAA/FAA International Conference Iceland, May 29-June 3, 2003

  2. Overview • RTSP Concept • CNS/ATM (r)Evolution • COM, SUR, NAV • Capstone - Implementing Change

  3. R T S P REQUIRED TOTAL SYSTEM PERFORMANCE "Performance Based" COM RCP NAV RNP SUR RSP ATM • Balance between Aircraft-ATS Requirements • Credit for systems and capabilities • Savings for ANSP - Reduced Infrastructure Requirements

  4. CNS/ATM (r)Evolution Promoting International Harmonization • Today: • RNAV • RNP • RVSM • FANS • VDL 1, 2, 4 • ADS-A & B • ACARS • Mode S, UAT • Avoiding divergent paths in Communications • Promoting convergence in Navigation and Surveillance

  5. CommunicationADS-B Link Decision • July 1, 2002 - two ADS-B Technologies • 1090 Extended Squitter • For high altitude airspace • For airspace principally used by domestic and commercial aircraft • SARPS and MOPS exist for 1090 ES • UAT • GA not capable of high altitude flight • If 1090ES alone cannot meet long-term goals, UAT provides a complimentary service • TIS-B on 1090 uplink • Reports for non-ADS-B and UAT equipped aircraft

  6. Dem/Val NEXCOM“Transition to Digital Communications” 5-10 years Next 5 years 10-15 years 15-20 years Enroute High Airspace VDL-3Link 0101010100110010101 0101010100110010101 0101010100110010101 01010101001 VDL-2 Datalink 0101 01010101001 RCAG 10011001011010101 Analog Voice ARTCC 01010 AFSS National Airspace Terminal Airspace • Analog Voice, 25 KHz • Initial Datalink (VDL-2) • Full Operational Evaluation& Exercise of Digital Voiceand Datalink (VDL-3) • Maintain Terminal Analog Voice • Implement VDL-3Digital Voice • Expand Datalink VDL-2Applications • Expand EnrouteDigital Voice (VDL-3) • Initiate TerminalDigital Voice (VDL-3) • Increase Datalink Capacity& Capability (VDL-2 & VDL-3) • Expand Digital Voice (VDL-3) to all domains • Expand Datalink Capacityin all domainsand all applications(VDL-2 & VDL-3)

  7. Advanced Avionics Surveillance Advisory Circular • Cockpit Display of Traffic Information (CDTI) • Automatic Dependent Surveillance - Broadcast (ADS-B) • Automatic Dependent Surveillance - Contract (ADS-C)

  8. AC on Airworthiness and Operational Approval of Surveillance • Joint Aircraft Certification and Flight Standards Advisory Circular • Provides an airworthiness to operational approval road map • Design approval guidance for appliance and installation • System safety assessment • Hazard classification and RTCA DO-178B software level • Air/Ground interoperability requirements • System validation tests • Aircraft ground and flight test • Operational approval process for applications • Operational safety assessment • Training requirements

  9. AC on Airworthiness and Operational Approval of Surveillance (cont) • Provide guidelines on the design approval of certain aircraft surveillance functions: • CDTI symbol set and human factors • TCAS II , CDTI and ADS-B target correlation • Airport Surface Situational Awareness (ASSA) • Traffic Information Service (TIS) • Integrated conflict detection systems • Surveillance display guidance for a Multiple Function Display • ADS-A position reports for oceanic/remote operations • 1090 MHz data link transponders • Universal Asynchronous Transceiver data link transponders

RVSM Implemented & PlannedAs of May 2003 Canada North 4/02 Canada South 1/05 Europe 1/02 Domestic US 1/05 NAT 3/97 Mid East 11/03 Pacific 2/00 Pacific 2/00 EUR/SAM Corridor 1/02 WATRS 11/01 **Western Pacific South China Sea 2/02 Asia/Europe South of Himalayas 11/ 03 CAR/SAM 2005 Australia 11/01 ** Western Pacific/South China Sea February 2002 Implementation Bangkok, Ho Chi Minh, Kota Kinabalu, Kuala Lumpur, Manila, Phnom Penh, Sanya, Singapore, Taipei October 2002 Implementation Hanoi, Hong Kong, Jakarta, Ujung Pandang, Vientiane Implemented Planned V. 6.8 5-23-02

  12. PROGRAM ELEMENTS Aircraft and Operators authorized by the administrator or… for non-US operators/aircraft, the appropriate authority Aircraft altimetry, autopilot, and altitude alert system modified, as necessary to RVSM standards RVSM policy and procedures incorporated into controller, pilot, and dispatch programs Air Traffic systems and programs revised

  13. PROGRAM ELEMENTS (cont) MONITORING: Aircraft altitude keeping observed to confirm performance standards are being met Ground and airborne monitoring systems used to independently monitor aircraft performance 3-5 Aircraft Geometric Measurement Element Clusters (AGHME) are being sited SAFETY ANALYSIS: Is being conducted on accepted Collision Risk Modeling Practices (ICAO Doc. 9574 v2) Completion by June 2004

  14. RVSM CONCLUSION • Implement DRVSM from FL290-FL410 in the airspace of the United States, Alaska, the Gulf of Mexico where the FAA provides air traffic services and possibly the San Juan FIR. • The United States, Canada, and Mexico are planning a joint implementation of RVSM. • DRVSM is proposed to be implemented on January 20, 2005 0901UTC.
