Go-ahead given for noise-abatement flight procedures DFS begins trial operations at Frankfurt Airport in early 2011 29 December 2010 – The Federal Supervisory Authority for Air Navigation Services (BAF) has approved three procedures from the active noise protection programme of the Airport and Region Forum for Frankfurt Airport (Forum Flughafen und Region). These procedures are the vertical optimisation of departure routes, dedicated runway operations (DROps) and the segmented RNAV (GPS) approach. DFS Deutsche Flugsicherung GmbH will first test these procedures in trial operations at the beginning of 2011. DFS, along with Fraport and Lufthansa, is thus keeping its promise to introduce noise-abatement procedures in the Rhine-Main area before the new runway northwest is opened. DROps and the vertical optimisation of departure routes will enter into operation on 13 January 2011, while the segmented RNAV (GPS) approach procedure will swiftly follow suit as soon as all preparations have been made. For capacity reasons, DROps and the segmented RNAV (GPS) approach procedure can initially only be applied between 23:00 and 05:00, whereas the vertical optimisation of departure routes does not have any time restrictions. The Umwelt- und Nachbarschaftshaus (environment and community centre) will conduct noise measurements during the trial operations. It should be determined, in particular, whether and to what extent the times of DROps and the segmented RNAV (GPS) approach procedure can be extended. The individual procedures are explained below: DROps This procedure entails the use of certain runways on certain days during the night. For example, on some days during the year only the take-off runway west (runway 18) is used for all departures, while on other days only the parallel runways (runways 25 and 07) are used. The aim is to protect some parts of the community on some days from aircraft noise as far as possible, and other parts on other days. It is thus inevitable that the areas not being protected are subject to more noise on those days. A new departure route from runway 18 towards the north-east will be especially established for DROps. Vertical optimisation of take-off procedures In the case of the vertical optimisation of take-off procedures, the aircraft should not exceed a maximum speed directly after take-off, and they should dedicate the excess energy towards gaining altitude. This helps the aircraft to climb more quickly and cause less noise in the communities in the vicinity of the airport. Segmented approach procedure The aim of this procedure is for inbound aircraft to fly around highly populated areas, such as the cities of Hanau, Offenbach and Mainz, at times of low traffic, i.e. mainly at night. DFS Deutsche Flugsicherung GmbH, the German air navigation service provider, is a State-owned company under private law and has 5,800 employees. DFS ensures the safe and punctual flow of air traffic over Germany. Staff coordinate up to 10,000 aircraft movements in German airspace every day, and nearly three million movements every year. This makes Germany the country with the highest traffic volume in Europe. DFS operates control centres in Langen, Bremen, Karlsruhe and Munich. In addition, DFS is represented in the Eurocontrol Centre in Maastricht, the Netherlands, and in the control towers of the 16 international German airports. DFS provides training and consultancy services around the world and develops and sells air traffic management systems, surveillance systems and navigation aids. The company's portfolio also comprises flight-relevant data, aeronautical publications and aeronautical information services. DFS has the following business units: Control Centre, Tower, Aeronautical Solutions and Aeronautical Information Management.
