ASAS and ADS-B

• Aena take part in a number of projects related to
  ADS-B enabled applications (including ASAS),
  among which
• MFF (Mediterranean Free Flight)
• MEDUP (Mediterranean Upgrade Programme)
• and will participate in
• C-ATM (Cooperative Air Traffic Management)
• SEAP (large Scale European ADS pre-implementation
  Programme)

Expectations and Concerns
ADS-B
ASAS
Pilots
Controllers
Ground ATM systems
Surveillance Sensors
Avionics
Clear responsibilities
Benefits
Costs
4
Benefits

• BENEFITS EXPECTED
• Increase efficiency of operations
• Increase capacity (?)
• ASAS Spacing
• promising in TMAs and some use in en route
• special case oceanic airspace
• Airport surveillance safety?benefits

5
Expectations and Concerns

• ASAS-TN
• ASAS is part of PACKAGE I
• BUT PACKAGE I includes ground surveillance
  applications
• Implementation of ONE of them paves the way for
  the other
• ADS-B PACKAGE 1
• ASAS PACKAGE 1

6
Benefits
ASAS?BENEFITS EXPECTED

• Similar ground and air infrastructure could
  allow the implementation of different air-ground
  surveillance applications enabled by ADS-B
• Similar ground and air infrastructure could
  allow the implementation of an improved airport
  surface surveillance
• availability of ASAS independent of ground
  infrastructure?
• depends upon the actual use of it.
• transition (TIS-B)?
• and controllers are still needed (F.
  Casaux, concluding remarks 1/2)

7
Concerns

• CONCERNS
• Need of clear and HARMONISED operational concepts
  and procedures.
• Sharing of responsibilities has to be very clear
• Package I?delegation of tasks BUT no delegation
  of responsibility?benefits?
• How to deal with aircraft of different
  performance ?
• Sequences in-descent are to be created for each
  specific environment (converging flows)?detailed
  studies

8
Concerns

• CONCERNS
• Where to start?
• (too) many new ideas
• Free Route, Free Flight, Transitions between
  different areas, ..
• Co-operative ATM, SWIM, dynamic sectorisation
• Can we start just in current environment
• Start simple
• fixed routes
• in particular areas
• .and then implement it together with other new
  ideas
• ?

9
Concerns

• CONCERNS
• Different technologies competing
• We should have clear operational concepts and
  requirements and THEN we should allow each
  possible technology to demonstrate their
  compliance.
• The selection of a technologyCAN BE DONE WITHOUT
  CLEAR OPERATIONAL CONCEPT?
• The deployment/installation of new technology
  (ground and air coordinated) is always very SLOW.
• What if wrong initial choice and deployment..?

10
Conclusions

• ASAS Operational Improvements Dream or Reality ?
• Further work has to be done to define the
  requirements expected (or needed)
• Further work is to be done on new standard
  procedures
• Further work is to be done on safety implications
• .... Many uncertainties are yet to be solved
• BUT
• Operators consider that ASAS Operational
  Improvements will be a reality
• ASAS combined with the other ADS-B enabled
  applications will provide important benefits to
  users

11
Final remarks

• The initial implementation (or pre-implementation)
  of package I applications (including ground
  surveillance) should be properly focussed.
• ?not linked to the introduction of other new
  concepts/ideas
• if linked to other issues
• ?high risk of making the problem too complex and
  thus nothing actually implemented
• The work already carried out should form a good
  basis to carry out initial trials
• New projects like C-ATM and SEAP will allow
  demonstrations of these applications

12
Final remarks

• Commitment
• ..to carry out trials?
• ..to deploy infrastructure (stations?full/partial
  coverage)?
• ..to change the ATM system?
• ..to implement new procedures?
• linked to cost-benefits and airlines equipage
