Title: Comparison%20of%20NextGen%20and%20SESAR%20Modernisation%20Initiatives
1Comparison of NextGen and SESAR Modernisation
Initiatives
By Don Ward Date April 2008
2The 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
3But, There Are Problems
- Aging, Inefficient, Unreliable and Costly Air
Transportation Infrastructure - Reaching the Limits of Capacity
- Rapidly growing concern over environmental impact
4NextGen 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
5Similarity in Regional Environment
- Pressures
- Growth-Capacity Conflict
- Environment
- Affordability
- Commercial Customers
- Obligations
- ICAO Oversight
- Opportunities
- Advances in Technology
- Procedure Improvement
6Differences 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
7NextGen SESAR Objectives are Similar
- Expand Capacity
- Global Aviation Harmonization
- Ensure Safety (with increasing capacity)
- Protect the Environment
- Improve Service for Aviation Customers
8NextGen 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
9NextGen A Look Under the Hood
10NextGen 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
11Trajectory-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
12Net-Centric Infrastructure Services
- Network Enabled Operations (NEO)
- Network Enabled Infrastructure (NEI)
- Network Enabled Weather (NEW)
System-Wide Information Management
13Weather 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
14Convective Weather Problem
15Layered 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
16Position, 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
17Airport Operations and Support
- Improved surface Information
- Potential use of Virtual Towers
- VFR-like operations when using instruments
18Safety Management
- Integrated evaluation, rather than relying on
post-accident data analysis - Identify emerging threats through improved
collection and analysis of safety data
19Environmental 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
20Surveillance Services
- Migration from ground-based surveillance to
satellite-based systems
21The 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

22Summary 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
