Responsibility at Finavia A part of society Safety Staff wellbeing Environmental responsibility GRI Aircraft noise control Read more about the noise control plan in the News Room! We are mitigating aircraft noise, among other things, by developing the use of runways and flight routes, as well as take-off and landing methods. Noise measurement stations at Helsinki Airport 9 Examples of noise control measures in 2016 • About 500 aircraft engine test runs are annually performed at Helsinki-Vantaa. The new run-up area was completed in autumn 2016 and, following tests, it became operational in December. The new run-up area will facilitate the control of noise arising from aircraft run-ups. • The Finnish Border Guard, which will move its helicopters from Malmi to Helsinki Airport at the beginning of the year 2017, prepared a noise control plan and carried out noise control measurements, in cooperation with Finavia. • The aircraft noise control plan at Helsinki Airport was updated in accordance with current practices. The report is available on the Internet and a printed version has also been produced. • A new take-off method optimised for new airliners and planned with capacity increases in mind was designed for Helsinki Airport runway 1 (22L). After its introduction, the noise benefits arising from the method were analysed with measurements. 4 7 5 10 1 6 2 3 Noise measurement stations at Helsinki Airport 1. Korso 6. Kerava 2. Tikkurila 7.

Responsibility at Finavia A part of society Safety Staff wellbeing Environmental responsibility GRI Continuous descent is used in 70 per cent of all approaches In continuous descents, the aircraft approaches the runway without the horizontal flight phase which would require flying at an altitude of a few hundred metres using high engine power. In these descents, noise is controlled by opening the flaps and landing gear as late as possible, and by steadily adjusting the speed. In 2016, a total of 70 per cent of planes landing at Helsinki Airport used the continuous descent approach (68). Even though Finavia is approaching the target values laid out in its environmental permit, they have not yet been achieved. There has nonetheless been an upwards trend, due to cooperation with air traffic control and airlines. At other airports, there is more scope for using the method as their airspace has less traffic. Other factors in the development of air-traffic noise Finavia’s noise control measures in a nutshell We are reducing air-traffic noise in a variety of different ways. Our goal is as little air-traffic noise as possible and as few inhabitants as possible in the area. The safety and fluidity of air traffic are always the priority. FINAVIA’S OPERATION HOW RUNWAYS ARE USED Principal runway for take-offs and landings OPTIMISATION OF FLIGHT PATHS Take-off paths to avoid residential areas as much as possible Active use of noise-abating flight methods QUIETER AIROPLAES THROUGH ENGINE TECHNOLOGY INNOVATIONS Development of aviation technology and the growth in aircraft size VECTORING OF LANDING ON RUNWAY 15 Landing planes are directed past the centre of Nurmijärvi. CONTINUOUS DESCENT OPERATIONS (CDO) Continuous descent approaches (CDA) USING THE LOW POWER optimising configuration LAND USE PLANNING Cooperation with planning authorities to take into account air-traffic noise areas NOISE LIMITS ON THE TAKE-OFF PATHS Some flight paths limited to low-noise aircraft Responsibility report 2016 51
