  1. EUROCONTROL European Organisation for the Safety of Air Navigation

  2. Colloquium on Environmental Aspects of Aviation Montreal, Canada 9 - 11 April 2001 Integrating Environmental Issues into Air Traffic Management (ATM) Operations George PaulsonDirector Safety, Airspace, Airports & Information Services

  3. The EUROCONTROL ATM 2000+ Strategy • Safety • Economics • Capacity • Environment • National security and defence requirements • Uniformity • Quality • Human factors

  4. EUROCONTROLEnvironmental Policy and Strategy • Working within international framework • Joint commitment of EUROCONTROL States • Environmental considerations integral to ATM decision making • Objectives • minimum impact at and around airports • compliance with international standards and regulations • mitigate aviation noise and emissions

  5. Reducing Emissions -ATM has role to play Estimate for ECAC area Potential savings from CNS/ATM • Additional potential fuel saving from CNS/ATM • 5% ICAO-CAEP WG/4, 2000 • 6 - 12% IPCC, 1999 • 7 % EUROCONTROL study, 1997

  6. EUROCONTROL Environmental Assessment Tools • Advanced Emission Model (AEM) • European Harmonised Aircraft Noise Contour Modelling Environment (ENHANCE) • Simulation tools • Air traffic movement database • 38 ECAC States • updated daily • Aircraft Performance Models

  7. ATM - Delivering Environmental Benefits • Air Traffic Flow Management (ATFM) • European Route Network Developments • Flexible Use of Airspace (FUA) • Reduced Vertical Separation Minimum (RVSM) • Area Navigation (RNAV) • Continuous Descent Approaches (CDA)

  8. Air Traffic Flow Management (ATFM) • Balance demand with capacity • Protect ATC systems from overload • Re-routings • avoid congested areas • Aircraft held at airports • engines shut down • avoid en-route and approach holding • avoid taxi queuing

  10. ATS Route Network Developments • European ATS Route Network developments • shorten average route lengths • increase capacity • Example - Sweden • new route network 1998 • net flight distance annual reduction of 3,2 million NM • annual flight time saving of 565,000 hours

  11. Flexible Use of Airspace (FUA) • Airspace available to all user groups • Security and Military needs satisfied • Shorter routings • More optimum flight profiles • Less fuel burn

  13. Reduced Vertical Separation Minimum (RVSM) on 24 January 2002 • 6 additional flight levels • Increase in airspace capacity • More optimum flight profiles • reduction in fuel carriage and fuel burn • Principal benefits • reduced delays •  200,000 tonnes fuel saved annually

  14. Area Navigation (RNAV) Procedures • Improved flight management • more consistent track-keeping • concentration of tracks • shorter direct routes • increased fuel efficiency • highly flexible • avoid noise sensitive areas • Key to continuous descent approaches • consistent • repeatable

  16. RNAV trial Nice Airport • RNAV - avoiding noise sensitive areas • Trial RNAV procedure • Co-operation between • DGAC France • EUROCONTROL • European Space Agency • GNSS technology

  17. CDA Conventional approach Continuous Descent Approaches (CDA) • Concept description • lower power settings • from higher altitude • no level-off segment

  21. Summary • Environmental Policy and Strategy in place • Working to establish ATM environmental objectives • Integrating environmental considerations into ATM implementation programmes and operations • Delivering operational ATM environmental benefits • ATM contributing to sustainable aviation growth
