Is ASAS /ADS-B needed for ANSP strategy?

• A consolidated starting point from
• DFS / AENA / LFV
• ASAS Thematic Network Workshop
• Toulouse, 2004-04-19

2

• yes

Concept in line withANC11 operational changes
International positionICAO, CANSO, IATA, AEA,
EUROCONTROL,

1. recognize ADS-B as an enabler of the global ATM
   operational concept bringing substantial safety
   and capacity benefits
2. support the cost-effective early implementation
   of packages of ground and airborne ADS-B
   applications, noting the early achievable
   benefits from new ATM applications and
3. ensure that implementation of ADS-B is
   harmonized, compatible and interoperable with
   respect to operational procedures, supporting
   data link and ATM applications

ANSP Needs for ADS-B package 1 strategy

• ADS-B package 1 It is a new surveillance
  function (different from the traditional one)?
  CHANGE IN SURVEILLANCE FUNCTION
• Package 1 includes air-ground and air-air
  surveillance
• Package 1 impacts on ANSP, Airlines and Infra
  structure responsible

5
ANSP Needs for ADS-B package 1 strategy

• Need to modify / develop functions in the right
  direction
• Need for guidance in order to find a more optimal
  cut between air / ground task redistribution
• Need common leads with airspace users , need to
  discuss around the strategy.
• Able to find synergies, share risks
• Enable SES implementation and harmonisation of
  services
• ADS-B (GS and AS) imply cross-border activities
• Meet Airspace users requirements on cost
  efficient services
• Start to lower the cost base

Incentives 1 (2)
Traffic volume
Automation incl. ASAS
ATC cost base
7
Incentives 2 (2)

• Package 1
• can act as a complement to radar (low levels,
  additional parameters)
• ADS-B stations can provide additional services
  (TIS-B, FIS-B)
• ASAS operations? Improved operations. Example
  sequencing and merging around the TMAs in
  specific scenarios
• ADS-B stations respect more the
  environment?Ecology
• ADS-B stations lower Costs!

Blunt ANSp need

• Do the right thing (when doing something even if
  it is very little)
• Connect to other ANSp (share risks and benefits,
  increase relevance of work done)
• Enable / support co-operative strategies / plans
  to take effect including ANSp, Airports, Airlines
  aiming for the SES environment
• Align national / regional strategies and plans
• Build the prerequisites for future business

9
ANSp SHORT term expectations

• Identify the rationale and argument for future
  international funding and ANSp resources
• Build initial business cases
• Come together with actors in COOPATS / ADS for
  strategic planning
• Connect to airborne / aircraft development
• Get focus on ground system issues I.e. ATM, CDM,
  AIS, FDP
• Build relations with actors in the Air transport
  system
• Identify short term benefits and deploy them
• Build partnership, consensus building

10
ANSp MID term expectations

• Refine business cases
• Initial task re-distribution (if needed)
• More efficient Air transport System starts to
  evolve
• Common view on the problem and way forward
• Co-operative solutions
• Co-operative progressive developmentand
  implementation work

11
ANSP LONG term expectations

• Good business
• Integrated Air transport System
• Refinement of task re-distribution based upon
  progress within technology, regulations, methods
  procedures

12
Practically this means

• ADS-B and ASAS strategy should address RD needs
• interoperability between 4D trajectory planning
  and ASAS applications
• how to solve transition issues
• workload issues for ATCO and pilot
• organisational issues
• how to cope with failures of system components
• backup solutions
• non-nominal cases

13
.it also means that

• Strategies of ANSPs should be aligned to GS/AS
  applications
• supported by structured approach of Package I, II
  and III
• ANSPs may select from the set of applications
  those that are best suited to their operations
• interoperability must be assured through common
  standards
• there must be a business case not only for
  airlines, also for ANSPs
• essential validated by supporting simulations
  with realistic assumptions

14
it is a complex area

• Consolidated requirements are needed in order to
  make ASAS happen

15
so a strategy is highly needed

• Do the right thing here and now!
• Connect to other actors
• Migrate towards common milestones / goals
• Implement..
• Follow up.
