Over 90 Offices Worldwide

Present Status Industry Total losses since 9/11 US$25 billion Expected losses 2003 US$10 billion Loading: Rising – Yield: Falling Airports and Air Navigation Charges US$40 billion annually: Rising !

Airlines and Communication Tool to conduct business efficiently to ensure safety to provide service to the passengers Capacity restrictions in air traffic reduced efficiency passengers satisfaction Increasing importance reduction of separation information need new applications

The Basic Needs Adequate capacity/Radio Spectrum Global connectivity Global interoperability Scalability Support Data/Voice/Video Support for all classes of communication traffic Cost effective

How do we get there ? Maintain present voice system 25 kHz 8.33 kHz in case of voice channel shortage Encourage use of data communications for Air Traffic Services: ACARS Satcom/HF data AOA FANS 1/A VDL Mode 2

Why no support for VDL Mode 3 or 4? Proliferation of system solutions No operational advantage versus present Voice and VDL Mode 2 Limited scalability - only option reduce time slots/bandwidth Outdated technology by 2015 Do not provide additional communication capacity

How not to proceed Additional capacity ? 2003 2015 2020 VDL Mode 3 VDL Mode 4 8.33 /25 kHz VDL Mode 2 2003 2015 Additional capacity ? 2020 New Operational Concept

How to proceed 2003 ITU WRC 2007 2007 2015 Impl. 2020 VDL Mode 3 VDL Mode 4 8.33 /25 kHz VDL Mode 2 2003 Mobile. Telecom Techn. New System Definition. ITU WRC 2007 2007 Standards 2015 Impl. 2020 New Operational Concept

Proven Concepts VDL Mode 3 and 4 Telecom Industry Digital systems Digital voice Directory of services Operation independent from ground station Telecom Industry Channel availability Open channels On demand Addressable voice Bandwidth on demand Scalability Dynamic frequency allocation

Incentives Operators that choose to invest should be provided with full benefits of the system not be disadvantaged by those that don’t While recognising the general principles of access and equity to airspace of all users Realisation of early and full benefits will strengthen the business case and motivation of stakeholders

Achieving Cost Effectiveness Sharing infrastructures COTS Limit system options Establish critical mass

Recommendations Cleary identify the incentives Improve global coordination of R&D, trials and operational implementation Seek for a global integrated system solution Closer association with telecommunications industry Encourage data link implementation . Airline Security To close the loop on improved security, IATA developed recommended Security Standards for its Member Airlines. These are based on ICAO Annex 17. These were approved by our Board and adopted by the full membership in mid 2002. Our goal is that all IATA airlines must have a Security Program in place and that program includes these Standards. Our recently launched IATA Operational Safety Audit or IOSA program will audit airlines from an operational security standpoint against these standards.
