Title: The ONESKY (Single-Sky) project and what it means for ASAS


1
The ONESKY (Single-Sky) project and what it
means for ASAS
  • A view on the results of the ONESKY project
  • By
  • R. Van Gent

2
ONESKY Project objectives
  • propose new EU airspace structure (Single Sky)
  • support an efficient traffic flow.
  • based on needs.
  • regardless of national frontiers.
  • acknowledging the geopolitical realities.
  • demonstrate that the proposals
  • will increase airspace capacity.
  • will decrease delays.

3
ONESKY Approach to the work
  • Fast time simulation study
  • TAAM, RAMS
  • Two lines of action
  • Optimise current airspace locally.
  • Redesign total EU airspace from scratch.
  • Two phases
  • Small scale partial designs.
  • Integration optimisation in overall model.

ONESKY - current linePadua Baseline Analysis
  • Traffic Density
  • Traffic Density Plot for LIPPN3 - 23/07/99

ONESKY Current line Padua Iteration 1
  • Re-direct southbound traffic west of BZO
  • Use existing route network
  • Original Routes
  • PITAR-BZO-SUMIR-ALBET
  • PITAR-BZO-ALESE-VIC
  • New Routes
  • PITAR-RENTA-ADOSA-ALBET
  • PITAR-RENTA-ADOSA-VIC

7
ONESKYPadua - Iteration 2
  • Re-directing northbound traffic west of BZO
  • Navigate via existing waypoints
  • Original Routes
  • VIC-ALESE-BZO-ENOGO
  • ALBET-SUMIR-BZO-ENOGO
  • New Routes
  • VIC-RENTA-ENOGO
  • ALBET-RENTA-ENOGO
  • Converging traffic at ENOGO

8
ONESKYPadua Iteration 3
  • Northbound traffic via ADOSA re-directed west of
    BZO
  • Original Routes
  • ADOSA-BORMI-BZO-MATAR
  • ADOSA-BORMI-BZO-BRENO
  • New Routes
  • ADOSA-BORMI-ENOGO-MATAR
  • ADOSA-BORMI-ENOGO-BRENO
  • Remaining Munich airspace allocated to Padova
    North

9
ONESKYPadua Results - Conflict Count
  • Decrease of 41 between the baseline and
    iteration 3
  • Decrease of 11 between optimisation1 and
    iteration3

10
ONESKYCurrent line Summary
  • Problem areas selected
  • Baseline 1999
  • Changes made to airspace since 1999
  • Iterations/designs based on TOSCAII
  • Comparative results obtained
  • Max gain in terms of delay-reduction is expected
    to be between 2 - 6

ONESKY conclusions
  • Single Sky initiative necessary for Europe
    (grid-lock imminent if not started soon)
  • 35 capacity increase can be expected!
  • But
  • Not much more!!

19
ONESKY study showsATCo workload is bottleneck
  • ATC function
  • Collision prevention
  • Expedite and Maintain traffic flow
  • Sector limit is around 35 aircraft an hour
  • Validated by a number of studies
  • Supported by Air Traffic Controllers
  • Sector size cannot be made too small
  • Transition time becomes too short
  • With increasing traffic more emphasis will go to
    Collision Prevention and less to Expedite and
    Maintain traffic flow resulting in higher charges
    for less service

20
The promise of ASAS (self separation)
  • Studies show crew workload hardly increases with
    densities up to 9 times present core European
    densities (due to the distributed nature)

21
ATM Paradigm Shift increased Efficiency and
more Capacity, with INCREASED SAFETY, by. . .
  • Delegation of responsibilities
  • Separation Assurance based on the best available
    aircraft position intent data (using ASAS
    technologies)
  • Co-operative Flight Planning . . .
  • all ATM participants share the same data,
    processed in closed loops
  • replace routine voice communication by data link
  • Weather independent TMA and Landing throughput .
    . .
  • with ASAS in combination with enhanced future
    landing systems
  • Enhanced airport surface movement . . .
  • ASAS will enhance safety (e.g. runway incursion)
    and efficiency of airport ground operation

22
But. Where/how to progress?
  • Real benefits are expected from delegated
    responsibilities/ self-separation
  • Core Europe too complex for self separation as
    first step
  • Package 1 applications are a good first step (for
    Core Europe)
  • However, there is more than Core Europe (ASAS
    initially seen as application for sparse density
    areas)

23
Conclusions / Suggestion
  • ATCo workload is the problem of present ATM
    paradigm
  • Delegate / transfer of responsibilities is needed
    (fast) to counter grid-lock
  • Start implementation of self-separation in sparse
    density regions parallel to Package 1 to also
    gain experience with autonomous operations
