Greener approach procedures for Munich

Continuous descent approaches in operations

DFS will commence “CDA transition and profile” trial operations in Munich airspace on 12 February 2009. The aim is to optimise the flight paths of approaching aircraft.
CDA, or continuous descent approach, is a procedure where the aircraft continuously descends at idle thrust for as long as possible after leaving its cruising level. Not only does this lower fuel consumption and thus costs for the airlines, but it also reduces CO2 and noise emissions. CDA is already being used as an established procedure in Frankfurt and now, after a successful trial phase, in Cologne/Bonn too.

By introducing the continuous descent approach in Munich, DFS is once again showing its commitment to act responsibly and handle air traffic in an environmentally and climate friendly way.

Depending on aircraft type, flight route and meteorological conditions, the CDA procedure can help to save between 50 and 150 kilogrammes of kerosene per approach, which corresponds to a reduction in CO2 of between 160 and 470 kilogrammes. Measurements taken in Frankfurt and Cologne/Bonn have shown that noise can even be reduced in the area 15 to 55 kilometres from the landing threshold. However, this procedure can, for operational reasons, only be used in times of low traffic, which at the moment is mainly during the night.

Through the trial operations in Munich, DFS expects to learn more about the positive effects on fuel consumption, CO2 and noise emissions.
