The objective of this three-day course is to provide a high-level understanding of aircraft noise, engine emissions and related environmental protection measures. Specifically in the vicinity of airports, aircraft emissions and their environmental impacts are a complex technical issue with many interactions that are often misunderstood by the stakeholders and affected parties involved. In particular, aircraft noise pollution around airports is often the most important limiting factor for airport development. Airports today are of critical economic and societal importance arguably, the emissions generated by aircraft have a major impact on the surrounding environment and, in the case of aircraft noise, are often a source of conflict between airspace users, airport operators, regulators and policy makers, and communities and their citizens.
