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, for example, aircraft schedules and 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 and emissions outputs (that characterise the main focus) and the use of methods to determine impacts (e.g. metrics, models, tools, databases).
However, to assess interdependencies, the use of a tool that integrates all environmental consequences 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 whilst some tools do exist (e.g. the FAA’s Aviation Environmental Design Tool and EUROCONTROL’s IMPACT tool) they are quite complex and generally used by the most experienced airports. What is needed is a more user-friendly set of tools that go beyond quantifying noise and emissions outputs to assessing impacts (e.g. on health) in a common framework
Information on aircraft operations, noise and emission outputs and assessment tools/metrics, associated with noise and emissions trade-offs can be found in Annex B.2 Operations.
