Advanced Safe Separation Technologies and Algorithms (ASSTAR) Project

ASAS-TN2 Workshop #1Malmö

26th-28th 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-2004-516140).

The programme started in January 2005 and has a duration of 30 months.

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 2010+ time frame

– ASAS manoeuvre design and execution

– Definition of supporting procedures

– Air & Ground installation & implementation issues

– Benefits

– Safety assessment

– Impact on Regulations


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

Impact on Roles and ProceduresImpact 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

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


ASEP-FLC


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)


ASEP-ITF


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
