1. ASSTAR Overview Jean-Marc Loscos, DSNA
Advanced Safe Separation Technologies and Algorithms (ASSTAR) Project Co-ordinator

2. ASSTAR USER FORUM Advanced Safe Separation Technologies and AlgoRithms
ASSTAR is sponsored by The European Commission – Directorate General RTD - within the 6th Framework Programme (contract number AST4-CT ).
Start: January End: November 2007

3. Consortium Partners: ANSP, R&D, industry, universities
EUROCONTROL

4. Project Overview ASSTAR is a EC Framework 6 STREP
Crossing and Passing Applications
Delegation of separation responsibility
Radar and Oceanic Environments
Research objectives support introduction in time frame
ASAS manoeuvre design and execution
Definition of supporting procedures
Air & Ground installation & implementation issues
Benefits
Safety assessment
Impact on Regulations

5. Operational concept
Airborne separation category according to PO-ASAS classification
Delegation of responsibility from the controller to the flight crew to execute a crossing manoeuvre with respect to one designated target aircraft.
The controller remains responsible for the separation with respect to the other aircraft in the sector.
Conditions
This is post AS/GS package I and ADS-B IN (and data link) would be available.
Traffic conditions would be similar to current situation for Controller tools.

7. AIRBORNE SEPARATION
Airborne separation will be based on airborne surveillance and airborne navigation.
The typical values could be expressed in TIME rather than DISTANCE.
Safety studies are required before promoting any reduction in the current ATC separation minima.
ASSTAR assumed several typical values for the applications:
5NM for ASEP-C&P in radar airspace
10 or 15 NM for ASEP-ITP in oceanic airspace
2 minutes or 5 NM for ASEP-ITF in oceanic airspace

8. Objectives for this session
One year ago in Rome, information on approach, methods and feedback from the audience, …including critiques….
The session of this afternoon is dedicated to present ASSTAR findings on the various applications:
Definition of the procedures (Applicability conditions, phraseology)
Operational benefits (safety, capacity, workload and task sharing)
Airborne systems requirements (algorithms, architecture)

9. More results should be presented at: User Workshop #5, 27th June 2007
Forthcoming events
More results should be presented at:
