Helsinki Airport on the leading edge of green landings
Nearly 60% of all aircraft landing at Helsinki Airport are already employing the "Continuous Descent Approach". This reduces the aircraft fuel consumption, emissions and noise.
Green landings result in a 10-30% savings in fuel and, in turn, exhaust emissions. For large aircraft, this can mean a savings of some 200 kilograms of fuel.
Correspondingly, carbon dioxide emissions are reduced by approximately 640 kg. The Continuous Descent Approach (CDA) also cuts down aircraft noise as far as 10 kilometres away from the airport.
Every effort is made to use the CDA whenever possible. CDAs require sufficient airspace, favourable weather conditions and the proper type of aircraft.
The number of CDAs employed at Helsinki Airport is among the highest in Europe. In the afternoon, there are a few peak hours during which time the CDA cannot be used due to parallel approaches.
