  • Balance between Aircraft-ATS Requirements

  • Credit for systems and capabilities

  • Savings for ANSP - Reduced Infrastructure Requirements


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


Communication ads b link decision
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

Program elements

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


Program elements cont

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


Rvsm conclusion
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
