Advanced Safe Separation Technologies and Algorithms (ASSTAR) Project ASAS-TN2 Workshop #1 Malmö 26 th -28 th September 2005 ASSTAR is a Specific Targeted REsearch Project (STREP) sponsored by The European Commission – Directorate General RTD - within the 6th Framework Programme (contract number AST4-CT ). The programme started in January 2005 and has a duration of 30 months.

page 5 ASAS-TN2 Workshop#1, September 2005 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

page 6 ASAS-TN2 Workshop#1, September 2005 Project Objectives  Establish a number of well-defined ASAS Package 2/3 applications  Reach a common endorsement between the airlines and ANSPs of the proposed applications  Regular project user workshops are planned to ensure the involvement of key users at the detailed level  Public User Forums to achieve wider dissemination and elicit responses from a broad representation of the Air Transport community

Work Package 1: Concept and Scenario Refinement (Work in Progress)

page 9 ASAS-TN2 Workshop#1, September 2005 Work Package 1  Define a set of applications and environments (scenarios) for the programme  Develop Operational Requirements Documents –Separate sections for each application  Initial benefits review  Implementation/architecture options  Preliminary risk/safety analysis

page 12 ASAS-TN2 Workshop#1, September 2005 Scenario & Application Priorities  Radar Environment –Lateral Crossing Application (ASEP-LC&P)  Pass Behind (Co-altitude and descending/climbing)  Pass In-front –Vertical Crossing Application (ASEP-VC&P)  Pass Above/Below  Non-Radar Environment –Enhanced Flight Level Change Procedure (ASEP-FLC) –Self-Separation on an OTS (SSEP-OTS) –In Trail Follow (ASEP-ITF)

Separation Applications

page 14 ASAS-TN2 Workshop#1, September 2005 Separation responsibilities

page 15 ASAS-TN2 Workshop#1, September 2005 Impact on Roles and Procedures  Controller is responsible for: –Conflict detection –Initiation of the application –Separation of other traffic from involved aircraft  Air crew is responsible for: –Selection of conflict resolution strategy –Execution of conflict resolution strategy –Informing controller when conflict has been resolved  New procedures will be required –Additional training for both controllers and flight crews

page 19 ASAS-TN2 Workshop#1, September 2005 Crossing & Passing  Based upon Package 1 application ASPA-C&P –Separate vertical and horizontal separation applications  ASEP-LC&P (Lateral Crossing & Passing )  ASEP-VC&P (Vertical Crossing & Passing )  Differences –Delegation of responsibility for separation  Similarities –Manoeuvre types –Application phases

page 20 ASAS-TN2 Workshop#1, September 2005 ASEP-FLC

page 21 ASAS-TN2 Workshop#1, September 2005 Enhanced Flight Level Change Procedure  Based upon Package 1 application ATSA-ITP  Differences –Active monitoring phase during flight level change –Aircraft are responsible for separation  Similarities –Applicability conditions unchanged (Could be extended though)

page 22 ASAS-TN2 Workshop#1, September 2005 ASEP-ITF

page 23 ASAS-TN2 Workshop#1, September 2005 In Trail Follow  Based upon Package 1 application ASPA-S&M  Differences –Aircraft are co-altitude in remain phase –Aircraft are responsible for separation –Extended duration (several hours) –Spacing defined in minutes rather than seconds  Similarities –Procedural termination condition - exit from track –Merge instructions can be used to initiate spacing at track entry

Self-Separation Applications

page 26 ASAS-TN2 Workshop#1, September 2005 Impact on Roles and Procedures  Controller is responsible for: –Transition from managed to self-separation airspace –Transition from self-separation to managed airspace –Provision of flight information services  Airborne domain is responsible for: –Conflict detection –Selection of conflict resolution strategy –Execution of conflict resolution strategy –Provision of flight status information  New procedures will be required –Additional training for both controllers and flight crews
