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 !

Why a new system ?
• Safety• Capacity• Efficiency
– Service improvement– Service costs– System costs
Technology is not the driver but the enabler !

COMMUNICATIONFunction, protocol, link
• The function itself: partly on the ground (ATC), partly in air: (cockpit).
• A protocol to establish contact• A link to provide connectivity • All 3 elements require investment and
operating cost, only the “function” will provide benefit.

Airlines and Communication
• The requirement– to ensure safety – to conduct business efficiently– to provide service to the passengers
• Adequate capacity– restrictions in air traffic– reduced efficiency– passengers satisfaction
• Increased reliance – reduction of separation – information need to support operations– new applications
![Page 14: An Airline Perspective on the implementation of new systems SEMINAR ON THE IMPLEMENTATION OF DATALINK AND SATCOM COMMUNICATIONS Bangkok Thailand, 17-19.](https://reader034.fdocuments.in/reader034/viewer/2022051515/551549a255034685568b5200/html5/thumbnails/14.jpg)
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
![Page 15: An Airline Perspective on the implementation of new systems SEMINAR ON THE IMPLEMENTATION OF DATALINK AND SATCOM COMMUNICATIONS Bangkok Thailand, 17-19.](https://reader034.fdocuments.in/reader034/viewer/2022051515/551549a255034685568b5200/html5/thumbnails/15.jpg)
How to satisfy the need ?
• Maintain present voice system– 25 kHz– Extend the use of 8.33 kHz if necessary
• Encourage the introduction of data communications for ATS:– ACARS– Satcom/HF data– AOA– FANS 1/A– VDL Mode 2– Mode ES
Development of one global common communication infrastructure

Dependent SURVEILLANCEFunction, Enabler
• A surveillance function resides in all aircraft (in a given (air)space) and at ANSP-facilities.
• Both Communication and Navigation contribute to a surveillance function.
• Navigation to provide the aircraft’s position (4D) and
• Communication to relay the message to all parties interested (broadcast).

Need for ADS-B ?
• Safety– Ground infrastructure costs
• Security ?• Efficiency
– Enhancement present procedures
• Capacity– Enhancement of present procedures– New ATM regime
• Costs– Service/System costs
![Page 22: An Airline Perspective on the implementation of new systems SEMINAR ON THE IMPLEMENTATION OF DATALINK AND SATCOM COMMUNICATIONS Bangkok Thailand, 17-19.](https://reader034.fdocuments.in/reader034/viewer/2022051515/551549a255034685568b5200/html5/thumbnails/22.jpg)
ADS-B Infrastructure costs
• Airborne infrastructure– One link -8 billion (80-90% integration)– Two links –10 billion
• Ground station infrastructure– One link 2 billion – Two links 2. 5 billion– ATC integration ?

Result !
• Resources wasted• Complexity of multiple links• Double/Triple infrastructure costs

What needs to be done
• Clearly identify/quantify role/benefit ADS-B in new ATM concepts
• Plan ADS-B implementation on a Regional basis conform ATM improvements
• Maintain principle of global systems
