An Airline Perspective on the implementation of new systems

An Airline Perspective on the implementation of
new systems

• SEMINAR ON THE IMPLEMENTATION OF DATALINK AND
  SATCOM COMMUNICATIONS
• Nairobi , 17-27 February 2004
• Presenter
• IATA

2
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

11
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

12
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 aircrafts 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

19
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 ?

IATA position

• ADS-B Prime enabler of new ATM concept
• Early cost efficient implementation
• Extension TCAS -1090 ES
• Phased implementation
• Global interoperability
• Business case !

Result !

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

25
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

26
What are the basic questions?

• When a new system
• Usage/Functionality
• Selection
• Standardization
• Certification
• Implementation
• Voluntary/ Mandatory
• Capacity/Efficiency
