3 km 4 km 0 km 1 km 2.5 km 3.5 km 2 km 1.5 km 0.5 km A320neo vs. A320ceo The Airbus A320neo (new engine option) has an approximately 50 percent reduced noise contour compared with the Airbus A320ceo (current engine option). The 85 dB(A) maximum noise level contours are shown for a takeoff with Lufthansa standard takeoff procedures and maximum takeoff weight (MTOW). By comparison, a maximum noise level of 85 dB(A) is produced by a truck passing at a distance of ve meters (16 feet) in city traf c. 0 km0.5 km 0.5 km 0 km0.5 km 0.5 km Air transport is unavoidably associated with the generation of noise, particularly in areas surrounding airports. For many years, the Lufthansa Group has worked to reduce these emissions increasingly and has applied numerous measures in the area of active noise protection. To this end, the Group also cooperates with partners in industry, public administrations, universities and research. The Lufthansa Group’s commitment to active noise protection is based on ve central points. These include investing in the most modern aircraft, retro tting the existing eet with noise-reducing technologies, conduct- ing noise research, and developing noise- reducing procedures for both approach and departure in cooperation with the system partners. Furthermore, the Company places great emphasis on the constructive dialogue with neighbors of airports and other interest groups. When implementing speci c mea- sures, the Group also takes into considera- tion the aspect of economic ef ciency. With regard to noise emissions, today 592 of 595 aircraft in the Lufthansa Group’s active eet already ful ll the currently stric- test Chapter-4 standard of the International Civil Aviation Organization (ICAO), which has been in effect since 2006 for new aircraft (see overview page 118). The new Chapter-14 standard will be applied for newly certi ed aircraft types from 2017, which will signi cantly lower the limit value yet again.
