The EUROCONTROL ATM 2000 Strategy

• Safety
• Economics
• Capacity
• Environment
• National security and defence requirements
• Uniformity
• Quality
• Human factors

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

6
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

7
EUROCONTROL Environmental Assessment Tools

• Aircraft Performance Models

• Advanced Emission Model (AEM)
• European Harmonised Aircraft Noise Contour
  Modelling Environment (ENHANCE)
• Simulation tools
• Air traffic movement database
• 38 ECAC States
• updated daily

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)

9
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
11
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

12
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

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

15
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

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

18
Continuous Descent Approaches (CDA)

• Concept description
• lower power settings
• from higher altitude
• no level-off segment
