3rd ASAS TN2 Workshop

"ASAS: Civil and Uncivil Practices"

The main objective of the Airborne Separation Assistance System Thematic Network 2 (ASAS-TN2) is to accelerate the application of ASAS and Automatic Dependent Surveillance Broadcast (ADS-B) operations in European airspace taking into account global applicability in order to increase airspace capacity and safety. The workshop is in the form of four sessions of presentations, each followed by a period of debate on key issues raised. The presentations and debate are recorded in the form of a workshop report to deliver key messages to the Air Traffic Management (ATM) community.


Day 1 - Monday 11th September:

Day 1:


 13:50 - 17:30 Session 1: Progress and status of implementation and standardisation.
Co-Chairs: Christos Rekkas (EUROCONTROL EHQ), Pierre Gayraud (Thales Avionics) Secretary: Chris Shaw (EUROCONTROL EEC)

The purpose of this session is to present what has happened in the ASAS domain since the last Workshop six months ago. Current ASAS standards development will be discussed including the US/Europe Requirement Focus Group and at the worldwide level. Status reports and plans for the use of ADS-B for ground surveillance as well as ASAS applications will be given by EUROCONTROL, FAA, air navigation service providers ,aircraft operators and aircraft manufacturers. An approach to integrating ASAS in SESAR (Single European Sky ATM Research) will be presented.

Introduction by the session leaders

Coffee break


17:30 - 19:00 Demo and poster session


Day 2 - Tuesday 12th September:


Session 2: UAV, military and business aircraft operations: ASAS implications.
Chair: Tony Henley (BAE Systems) Secretary: Peter Howlett (Thales ATM)

ASAS applications can be seen as enabling civil aircraft to undertake formation flying and spacing applications that are today routine for the military. There are two aspects to this session - what lessons can be learnt from the military operating experience with reference to nearby aircraft and second, how will the introduction of ADS-B and ASAS applications impact the future development of Business Jet flight decks, military interoperability and civil/ military UAV (Unmanned Aerial Vehicles) operations?

Introduction by the session leaders

Coffee break

12:00 - 13:30 Lunch

13:30 - 17.00: Session 3: Human performance, Human factors and a Cognitive systems approach to ASAS operations
Chair: Billy Josefsson (LFV) Secretary: Giorgio Matrella (ENAV)

A continuing theme that has featured in all ASAS workshops is the consequences for the human in ASAS operations. The purpose of this session is to introduce the human factors and human performance aspects of ASAS operations based upon the body of knowledge that exists today. It will also address the necessary research required to ensure that human issues are resolved. Among the topics to be considered are: - A critical appraisal of human performance, both air and ground - Cognitive systems engineering approach to ASAS operations - Human factors/performance research agenda for ASAS implementation

Introduction by the session leaders

Coffee break

  • The pilot and human performance issues, Bob Arnesen (IFALPA)
  • Cognitive engineering perspective of ASAS, Amy Pritchett (Georgia Tech)
  • A model of cognitive systems and ASAS that supports an ASAS human performance research agenda, Lena Martenson (KTH Sweden) and Anthony Smoker (IFATCA)


18:30 - 21:00 Social Event sponsored by BAE Systems


Day 3 - Wednesday 13th September:


8:45 - 12:30 Session 4: Towards ASAS Package 2
Chair: Nico de Gelder (NLR) Secretary: Soren Wikerud (LFV)

The purpose of the session is to look at future steps and issues in the ASAS domain and will focus on airborne surveillance applications beyond ASAS Package 1. One of the main issues is the transfer of separation responsibility from the controller to the flight crew.
Among the topics to be addressed are:
- how to safely transfer separation responsibility (two ways): what does recent research tell us?
- what are emerging technologies as complementary ADS-B data links?
- how do safety methodologies cover transfer of separation responsibility?
- what are future operational improvements using ADS-B/ASAS concept elements?
- how do these concept elements fit together and fit in a future ATM system?


Introduction by the session leaders

  • NASA Research Results in 4D-ASAS, David Wing & Bryan Barmore (NASA)
  • ASSTAR: Airborne Separation Operations in Oceanic Airspace, Bob McPike, (NATS)
  • ASPASIA: Benefits of new SatCom technologies to ASAS, Toni Paradell, (Atos Origin)
  • Safety risk assessment of airborne self-separation, Henk Blom, (NLR)
  • NGATS (Next Generation Air Transportation System) Airspace Research, Harry Swenson, (NASA)
  • ASAS in the ATC Domain Strategy, Dragos Tonea, (EUROCONTROL EHQ)

12:30 - 13:00 Session 5: Summary & Close
