The ASAS Challenge Today
How to accelerate the implementation of ASAS?

Presentation Objectives

• Raising some key issues in order to support the
  discussions on users expectations and concerns.
• Issues to be addressed
• Interoperation, how does it change the
  environment, delays, standards, military, ATC
  sectors, single sky.
• Objectives transition aspects, mixed equipage,
  time scales, interoperability between various
  types of operation (e.g. military, GA, Airlines)
  and between ACCs (e.g. single sky).

The Context

• Temporal
• Package 1 2007-2012
• Packages 2/3 from 2012 onwards
• Operational Enviroment
• Oceanic
• Continental
• En-route
• E-TMA, TMA
• Airport
• ASAS Application
• ATSAW
• Spacing
• Separation
• Self-Separation

5
Conceptual Changes for the Future

• Co-operative services to air traffic, managing
  the flight trajectory
• Strategic organisation of traffic flows and
  extended levels of automation
• Flight management from gate-to-gate
• Enhanced flexibility and efficiency
• Collaborative decision-making
• Responsive capacity management to meet demand
• Collaborative airspace management

6
Issues Related to the Conceptual Changes

• An essential element of these changes is
• the timely open access to and availability of
  consistent, validated and up-to-date information
  about
• airspace availability conditions (ATM
  environment),
• flights intentions and their operating conditions
  
• shared by all of those involved in their planning
  and execution (aircraft operators, en-route ATC,
  ATFM, airport ATC, and airport operators and
  other interested authorities).
• ASAS impact
• ASAS is an essential tool to enhance flexibility
  and enable efficicency increases.
• Can it reduce the quality (i.e. accuracy) of the
  flight intentions available for the planning?
• Will it reduce or improve the ATM network
  predictability?

7
Changes Further Ahead

• Being defined by the ACARE initiative
• Elements of the 2020 targets
• One man cockpit
• Automated Flight
• Automated Air Traffic Control
• ASAS Issues
• Will the future ASAS target only at preventing
  collisions?
• Or will it also aim towards expediting and
  maintaining an orderly flow of traffic?

8
Interoperation with system elements 1

• ASAS and ACAS
• at the level of procedures
• at the level of systems (datalink and CDTI)
• Airspace Users
• Business aviation
• will benefit of the increased flexibility and
  efficiency
• Military
• Can ASAS improve access to military airspace?
• Datalink Technologies
• Multipe ADS-B links used simultaneouly.
• Multiple CPDLC links used simultaneously (ATN,
  FANS-1/A)
• Other datalinks (ACARS, Satellite, HF datalink,)

9
Interoperation with system elements 2

• Impact on ATC Tools
• Such as Arrival Manager, Medium Term Conflict
  Detection
• How will the new ASAS clearances be used by these
  tools?
• Airspace Structure
• Impact of ASAS on Airspace Design to improve ASAS
  efficiency
• Will ASAS improveDynamic Sectorisation?
• Will ASAS have an impact on the Multisector
  Planner role?
• How will ASAS improve the Functional Airspace
  Blocks in the European Upper FIR
• ASAS navigation requirements
• precision on the ground to improve airport
  operations
• accuracy and reliability on the air

10
Interoperation with system elements 3

• Airports
• Can ASAS reduce the CFMU time window by
  providing more flexibility and capacity?
• Improvements to airport mangement and sequencing
  using ASAS
• How will ASAS contribute to the approaches to
  optimise runway use
• AOC
• Can ASAS contribute to the fleet management
  issues by enabling more sharing of information?
• How will ASAS provide AOC with the predictability
  they need?

11
Transition

• Between airspace types
• different ASAS procedures in oceanic and
  continental
• alredy a problem for CPDLC
• Between ASAS levels
• Can ASAS applications of different levels coexist
  in the same airspace?
• And in contiguous airspaces?
• Would it be confusing for Pilots?
• Mixed equippage
• Mandate
• Segregated Airspace
• TIS-B as a complement?

12
Other Issues

• Environment, how will ASAS
• decrease emissions (reducing holdings)
• reduce noise (via less speed variations)
• reduce the industrial impact
• Security
• How can ASAS be made less vulnerable than todays
  ATC?
• Should ADS-B be encrypted?
• Should anybody have access to intent data?

13
Questions?
It took one of the greatest minds who ever lived
to design it, but it took 500 years to find a man
with a brain small enough to actually go and fly
it.
