Introduction (1)
• ATM operations are a complex interaction of dissimilar activities• Frequently no physical links exist between them• In Europe the 100 main airports are:
• connected by approx. 600 airspace segments • controlled by 65 ATCC’s with many systems• operated by 38 ANSP’s with different cultures
• Terrestrial communications usually fixed point-to-point links• Information sharing often limited• Coordination & management frequently dysfunctional• No common situation picture of ATM operations exists

Introduction (2)
Lack of a common picture and effectivein-time communication and cooperation
Improved situational awareness would benefit all
ATM IS FACED WITH A PARADIGM SHIFT
LITTLE COST
Effective means of understanding and cooperation will result in reduced capacity loss and an increased system through-put
NEGATIVE IMPACT

The Paradigm Shift
CREATING THE PARADIGM SHIFT
• Establish culture of information sharing, to• Enable True system interoperability • Deliver a complete, accurate & temporal situation picture common to ground/air • Through evolution of the Net-centric information environment
![Page 5: Towards a Common Understanding · Towards a Common Understanding Creating the Network-centric Environment ... • No common situation picture of ATM operations exists. 3 Introduction](https://reader030.vdocument.in/reader030/viewer/2022041009/5eb4716b4c6f3d060741367c/html5/thumbnails/5.jpg)

Overview
The Net-centric Environment…………..
“the true Intranet of ATM”
• Challenge is to create a regulated environment covering multiple & diverse actors from
• ATM and non-ATM Domains
• The key to this Symposium
![Page 6: Towards a Common Understanding · Towards a Common Understanding Creating the Network-centric Environment ... • No common situation picture of ATM operations exists. 3 Introduction](https://reader030.vdocument.in/reader030/viewer/2022041009/5eb4716b4c6f3d060741367c/html5/thumbnails/6.jpg)

Overview
• Based on Net-centric Enterprise Architecture………
“light-weight, massively distributed, horizontally-applied architecture, that distributes components and/or services across an enterprise's
information value chain using Internet Technologies and other Network Protocols as the principal mechanism for supporting the distribution
and processing of information services”
• In ATM and SESAR especially referred to as the‘Concept of System Wide Information Management (SWIM)’
• Short/medium term evolution through Aeronautical Information Management - AIM

Aeronautical Information Management AIM
• Human AIM• Institutional AIM• Quality AIM• Digital AIM

What is AIM?
• Reflects changing ATM environment• Emphasis on flexibility & interoperability• Recognises need to transit from products to data• Envisages the “pooling” of selectable data for tailored
application from significantly expanded data sets• Is a Concept, a System & a Service
• WHAT, WHY and to an extent HOW• NOT WHO – for States/industry to decide
• Is short/medium term implementation of net-centric INF ENV described in SESAR ATM Master plan
• Forms basis of Eurocontrol CND IM Strategy, an elaboration of the Master Plan

AIM Basics
• Digital provision of quality information• Move towards a state of information sharing and
exchange• Based on Enterprise Architecture & Service Oriented
Architecture (SOA) concepts aligned with• SESAR• Trend towards Network Centric Operations
• Will follow & leverage existing global and open interoperability regulations & standards
• Time line to 2020 & transition to SWIM

AIM evolution
• Information On-demand• Information filtering based on location and time (4D) to
• support of future 4D trajectory management, and• collaborative decision making
• Static and dynamic information fusion• Seamless information sharing• Open solutions• Innovative digital services and products• Improved situational awareness

AIM IM Functions
• (generic) AIM Information Management Functions• Quality, Content & Distribution• Maintenance & updating• Exchange & access• Description & discovery• User identity & profile• Security & authentication• Notification• Digital data rights• Charges etc
• Each IM function implies information sharing• Extended Data Models to cover shared information
management requirements• Global rules & regulations are needed for safe & effective
management

Information Management In Europe
• Essential nature of IM reflected in SES Regulation
• Requires unbundling of services, an institutional change
• Further regulation such as aeronautical data quality on way
• The SESAR ATM Target Concept• Transition from ICAO Flight plan to 4D Business Trajectory
• Transition to Network Centric Operations
• Based on Service Oriented Architecture (SOA) principles
• Compliant with ICAO ATM Target Concept
• IM a key enabler of SESAR ATM Target Concept
• IM Strategy second pillar of Eurocontrol CND realignment
• Key component Reference Model for ATM IM: RM-ATM-IM

Conclusion
• AIM much more than “modern” AIS• Embraces ALL ATM information needs• Based on open requirements, open standards, and open
exchange models• Pace of change accelerated by SESAR & NextGen• SESAR & Eurocontrol IM Strategy in support will define
WHAT, WHEN, HOW but not WHO • Technology not the issue, institutional & resource issues
are• ICAO is key to standardised & harmonised global change
& management• Symposium marks the start in the Paradigm Shift
