A review of Tools used for noise or/and emissions, screening existing knowledge
Various information is required for the development of environmental studies and/or assessments, including trajectories, flight plans, aircraft engine specifications, aircraft performance data, as well as statistical data regarding the number of the population living in the proximity of airports.
Almost all necessary and relevant data regarding interdependencies' studies can be grouped into three categories: flight information, noise, emissions (that characterise the main focus) and the use of metrics (method, model, tools, databases).
However, to assess interdependencies, the use of a proper tool is needed. Here, more research is required to develop an environmentally friendly, easy to use tool that will assess noise and emissions at the same time.
It is important to underline that, in general, the airports are still using separate tools for noise or/and for emissions when assessing interdependencies. This shows the lack of a common tool (or tool suite) to determine noise and emissions trade-offs.
Information on aircraft operations, metrics and tools, associated with noise and emissions trade-offs can be found in Annex B.2 Operations.
