An important part of improving any system is the need to be able to assess the benefits that are derived from the changes. EUROCONTROL has developed a suite of tools which provides a framework to study environmental impact of ATM measures such as new runways, new ATC procedures, new air-route structures, new aircraft types, increased demand, etc.
Such changes are evaluated by their impact on local air quality, noise, global emissions and associated interdependencies in order to identify solutions that minimize their environmental impact.
In order to make these tools more widely available EUROCONTROL has put in place a contract with industry which ensures the tools deployment, maintenance, future evolutions and support to the users community.
Under current plans, the following models will be made progressively available from April 2009 onwards:

|
|
|
|
| |
 |
AEM (Advanced Emission Model) |
| |
|
ALAQS (Airport Local Air Quality Studies) |
|
|
|
|
|
Most of the models are driven by four-dimensional flight profiles (sources include the CFMU, radar, fast-time simulations, real-time simulations and flight data recorders). They are closely coupled to international databases (for example: the Aircraft Noise and Performance database, ICAO engine emissions databank, weather information, Geographical Information System data) to provide efficient support to decision makers and to help evaluate achievement of targets.
The models have been developed in conjunction with the appropriate ECAC, EC and ICAO environmental groups to ensure that they support harmonised European and Global assessment standards and protocols. This will reassure internal and external stakeholders that any impact assessments based on these products meet recognised international standards.

Close liaison with the United States Federal Aviation Administration (FAA) is maintained on models and methodologies, in particular in support of harmonisation activities within ICAO’s CAEP process.
The use of the tools will be governed by terms and conditions of the EUROCONTROL licence agreement by using a web licensing system. Following a favourable approval of the request, the tools will be provided to the requester. The use of the tools including maintenance and support will be free of charge. However, a user might be requested to participate in the cost of handling fee (per tool).

|
|
The support service will be ensured through a dedicated web site. Registered users will be provided with a user name and password in order to access an application where they will have the possibility of expressing any needs or requirements as well as inform us of any discrepancies with the system.
This application will keep a record of the requests and users will be informed of any modification or upgrades based on ticket acknowledgments.
