1 2 3 4 3 5 5 39Responsible Corporate Management In the form of MAR, DFS has been testing a further approach procedure at Frankfurt Air- port since 2014. This abbreviation stands for “modified arrival routes”. The new procedure involves the raising of minimum flight altitudes before and in the first part of the northern and southern downwind approach routes by up to 2,000 feet (approximately 600 metres). The higher flight altitude provides the local populations under these approach areas with some relief. Bundled approaches create breaks in noise A further example of active noise abatement is the “dedicated runway operations” proce- dure (DROps), which aims to reduce noise in the departure area by using alternate run- ways. This procedure, which started regular operation in 2013, provides for a bundling of takeoffs on defined takeoff runways or de- parture routes depending on the direction of operations between the hours of 5 a.m. and 6 a.m. This system creates breaks from noise for people living in the vicinity of the routes not being used. As the planes take off on parallel runways in an easterly or westerly direction depending on the wind direction, there is a specific DROps system for flight operation which also includes takeoffs from the west takeoff runway. In any case, construction measures on the runway system may have the effect that the procedure cannot be used on certain days. A modified DROps procedure in the form of the “noise breaks model” is expected to be introduced into trial operation in April 2015. This should facilitate relief from noise during the night through the alternat- ing use of runways – including for landings. However, operational or infrastructural re- quirements may also lead to the suspension of the procedure. Creating breaks in noise Thanks to the DROps procedure, heavily burdened residential areas are provided with relief at particularly sensitive times. Takeoffs on certain run- ways or routes are bundled together to achieve this. Flying around urban areas In order to lighten the burden on as many areas as possible, takeoffs and landings have been optimized or reorganized. This is also supported by the installation of a satellite-assisted, precision ground-based augmentation aid to enable higher and quieter landing approaches. Flying higher Downwind approaches are raised from 3.0° to 3.2°. Noise is reduced through the raised gliding angle. Flying more quietly Noise-based fees for takeoffs and landings create incentives to use quieter aircraft. Active noise abatement Passive noise abatement measures include the conversion of windows, shutters, roofs, walls, and the installation of fans. The implementation of the potential measures depends upon the structural requirements of the property. Passive noise abatement 2014 Compact
