Comparison of NextGen and SESAR Modernisation
Initiatives

• ASAS TN2
• Paris

By Don Ward Date April 2008
2
The Driving Need is Similar for NextGen and
SESAR

• One Billion Passengers in U.S. Skies by 2015
• Potential for Triple Demand by 2025
• New Entrants Such as Very Light Jets
• Global Market Opportunities
• Travel and Tourism Growth
• Aviation and Aerospace represent a large portion
  of GDP

3
But, There Are Problems

• Aging, Inefficient, Unreliable and Costly Air
  Transportation Infrastructure
• Reaching the Limits of Capacity
• Rapidly growing concern over environmental impact

4
NextGen Goal Achieve a Next Generation Air
Transportation System that meets the nationss
future air transportation safety, security,
mobility, efficiency, and environmental needs
SESAR Goal To achieve a performance-based
European ATM System, built in partnership, to
best support the ever increasing societal and
States (including military) expectations for air
transport with respect to the growing mobility of
both citizens goods and all the other aviation
activities, in a safe, secure environmentally
sustainable cost-effective manner
5
Similarity in Regional Environment

• Pressures
• Growth-Capacity Conflict
• Environment
• Affordability
• Commercial Customers
• Obligations
• ICAO Oversight
• Opportunities
• Advances in Technology
• Procedure Improvement

6
Differences in Regional Environment

• Geography
• Weather problem
• Traffic distribution/density
• ATM Service
• Number of Service Providers
• Source and methods of Finance
• Market
• General Aviation
• Culture and Politics
• Number/Diversity of States

7
NextGen SESAR Objectives are Similar

• Expand Capacity
• Global Aviation Harmonization
• Ensure Safety (with increasing capacity)
• Protect the Environment
• Improve Service for Aviation Customers

8
NextGen Construct differs from SESAR

• Institutional
• U.S. Government is ANSP (wont change any time
  soon)
• FAA funding is not cost-based
• FAA includes regulation and service provision
• Different stakeholder balance
• Major lobbies for GA and business users, single
  military presence
• Scope
• NextGen curb-to-curb, security,
• Industry involvement different
• NextGen is more government owned and driven
• Industry participation is through the NGATS
  Institute to avoid competitive issues

9
NextGen A Look Under the Hood
10
NextGen Functional Areas
Trajectory-Based and Performance-Based Operations
and Support
Airport Operations and Support
Safety Management
Environmental Management Framework
Layered Adaptive Security
Net-Centric Infrastructure Services
Weather Information Services
Positioning Navigation and Timing Services
Surveillance Services
11
Trajectory-Based and Performance-Based Operations
and Support

• Services and Operations based on precise
  trajectory execution
• User preferences are accommodated as best
  possible
• 4D-/Business Trajectories are digitally
  exchanged among aircraft, operators, and service
  providers
• Use four-dimensional trajectories to analyze and
  predict system behavior

12
Net-Centric Infrastructure Services

• Network Enabled Operations (NEO)
• Network Enabled Infrastructure (NEI)
• Network Enabled Weather (NEW)

System-Wide Information Management
13
Weather Information Services

• Net-centric weather information is made available
  and understandable to all approved users
• A reliable virtual, common weather picture is
  foundational for optimal air transportation
  decision-making
• Emphasis is not just about improving forecasts,
  but on making better decisions with available data

14
Convective Weather Problem
15
Layered Adaptive Security

• Adaptive Security for People, Cargo, Airports
  and Aircraft
• Risk Assessment-Driven Evaluation and Response
• Positive Identification for People and Cargo
• Preventive Threat Detection and Mitigation

16
Position, Navigation and Timing Services (PNT)

• Air routes are independent of the location of
  ground-based navigation aids
• RNAV is used everywhere RNP is used where
  required
• System performance meets operational needs to
  service the demand
• Increased availability of guided approaches at
  smaller airports

Mostly for general aviation with lower minimums
17
Airport Operations and Support

• Improved surface Information
• Potential use of Virtual Towers
• VFR-like operations when using instruments

18
Safety Management

• Integrated evaluation, rather than relying on
  post-accident data analysis
• Identify emerging threats through improved
  collection and analysis of safety data

19
Environmental Management Framework

• Holistic approach to impact on environment
• Fuel savings and reduced emissions noise are
  central goals to NextGen
• Continuous Descent Approach will be an early
  demonstration program for NextGen

20
Surveillance Services

• Migration from ground-based surveillance to
  satellite-based systems

21
The Integrated Work Plan

• Provides the integrated framework to achieve the
  NextGen vision across all major development
  partners.
• Builds upon the framework presented in the 2004
  Integrated Plan
• Describes the transition from the current to the
  end state defined in the NextGen Concept of
  Operations and the Enterprise Architecture.
• A dynamic instrument continually refined and
  enhanced to reflect current priorities, budgets
  and programs

IWP will be the JPDO plan to achieve NextGen

Summary of Key Characteristics for NextGen and
SESAR

• Shift to increase User Focus
• User preferences and business models
• Distributed and Collaborative Decision-Making
• Distributed, but optimize on Network Plan
• Implement Just Safety Culture/Safety Management
• Take advantage of Automation Tailor automation
  to assist humans
• Human role will shift to ATM, with less emphasis
  on tactical control
• Reduce Impact of Weather
• Equivalent Visional Ops for NextGen
• 80 equivalence for SESAR
• Common weather picture and improved decision
  support
• Migrate to digital and satellite-based
  technologies

ASAS Self Separation

• Nextgen and SESAR both plan to migrate Separation
  method from ATC as done today, progressing to
  airborne self-separation
• NextGen (EN-0032) Self Separation timeline 2022
• SESAR timeline is IWP3 post 2020
