Equipping for ASAS: Ground and Airborne Industries

To support the expeditious development and implementation of ASAS applications the Airborne Separation Assistance System (ASAS) Thematic Network (TN) held its fifth workshop entitled “Equipping for ASAS: Ground and Airborne Industries” in Toulouse on the 17 to 19 September, 2007. The event was delivered in conjunction with the Flysafe project.

In addition to the workshop, the ASAS-TN2 team took the opportunity to present to a joint IATA/AEA forum at NLR on the 8 October in order to allow the key messages to reach the airlines. Pilots from the airlines were able to fly some ASAS applications in the NLR GRACE simulator.

This is a key time for ASAS development with the advent of SESAR in Europe and NextGen in the US. It is crucial that there is a common global understanding of ASAS issues and that ASAS is placed correctly in the context of these two continental initiatives. It is important that globally applicable standards exist and that ASAS development, validation and operational initiatives are shared with all concerned. There are several key ASAS applications that will provide safety, efficiency and economic benefits.

ASAS-TN2 and Flysafe Project Objectives

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.

As air traffic is expected to triple within the next 20 years, FLYSAFE addresses the need for new systems and solutions to increase air traffic safety in this context. It focuses particularly on areas identified as the main causes of accidents around the world: loss of control, controlled flight into terrain, and approach and landing. FLYSAFE will address three main hazards - atmospheric conditions, traffic, and terrain - by providing pilots with new systems allowing them to make the right decision at all times.

The Fifth Workshop “Equipping for ASAS: Ground and Airborne Industries”

The workshop is the last in a series of five ASAS-TN2 project workshops. Four similar events were held by the preceding project, ASAS-TN1. The TN2 project will conclude with a seminar in Paris in the spring of 2008.

The fifth workshop focused on ASAS issues in four sessions:
  • European and US plans and progess
  • ASAS in the Context of SESAR and NextGen
  • Flysafe project
  • Ground and Airborne Industry
All project information for TN2 and TN1, including reports of the workshop proceedings, presentation material and a library of ASAS-Related documents, can be found on the ASAS Thematic Network web-site:

Workshop conclusions

It is a critical time for ASAS development. Its inclusion and correct placement in the SESAR and NextGen concepts and implementation programmes is vital if the full benefits of ASAS applications integrated into the future ATM system are to be realised.

There are many similarities between SESAR and NextGen and they need to remain in step and compatible with one another. The community can use the FAA/EUROCONTROL Action Plans to facilitate this – Action Plan 23 (AP23) for ASAS. A common strategy for validation and implementation that shares and builds upon each other’s results should be developed.

A number of applications are relatively simple and can deliver safety and economic benefits in the short-term; surface applications, sequencing and merging, and the oceanic in trail procedure are candidates.

Progress can be achieved by building upon the structure of the CASCADE/CRISTAL projects so that pioneer airlines can start to use some ASAS applications in specific locations.

For long-term development of ASAS applications there needs to be a focus now on those applications which will take time to develop and which we expect will give significant benefits e.g. self separation (SSEP) and cruise climb.As part of the deployment of ASAS applications, a development plan is required with the minimum number of avionics system upgrades.
