In total, 157 short- and medium-haul aircraft are being equipped with a vortex generator. The noise-reducing components are located on the underside of the wings. Newly built Airbus aircraft have already been delivered to Lufthansa with the sound-reducing technology since the beginning of 2014.
Another initiative to reduce aircraft noise will be intensively tested in the next few weeks in flyover measurements over several days at Magdeburg-Cochstedt Airport with two MD-11Fs from Lufthansa Cargo.
Modified sound suppression has been installed on the engine intakes of the General Electric CF6-80C2 engines. In addition, Lufthansa expects to reduce landing gear noise by covering the cavities in the aircraft’s landing gear.
