Finavia aims for as few people as possible to be affected by aircraft noise. Noise is controlled by planning routes and directing aircraft to the most appropriate runways and by restricting access of the loudest aircraft to the airports.
Aircraft noise is mainly engine noise or aerodynamic noise. The development of aircraft and engine technology has reduced noise significantly. New jet engines are quieter than earlier models and their energy efficiency is better. Propeller aircraft - which are quieter than jet airplanes - are used frequently on short flights in particular.
Finavia recently launched its three-year Continuous Descent (CD, so called green flights) development project, which aims for broader adoption of more environmentally friendly aviation practices.
