DLH_Balance_2016_ENG - Most stringent noise standardsfor the Lufthansa Group’s fleet

Active eet of the Lufthansa Group on December 31, 2015 in EPNdB Of the 595 aircraft in the Lufthansa Group’s active eet, 592 ful ll the strin- gent Chapter 4 noise standard of the International Civil Aviation Organization (ICAO). The most important element of Chapter 4 is the minus 10 EPNdB crite- rion (Effective Perceived Noise dB); see the vertical broken line in the overview on the left. The limits depend on the aircraft’s maximum takeoff weight and number of engines. The bar chart indicates the sum of the differences between the measured value and the threshold value at the three measuring points by type of aircraft (cumulated margin). Where necessary, the values based on the reduced maxi- mum takeoff weight prevailing in ight operations are indicated. To allow a more transparent depiction, an improved method of analysis was developed for the previous issues of Balance, which include the individual noise certi cate data of all Group aircraft. Different ver- sions of an aircraft and its engines by year of construction are thus better taken into account. Accordingly, the value ranges from the lowest to the highest cumulated margin are indicated for many eets. The analysis also takes into account any modi cations to aircraft or engines that have been made in the meantime, thereby leading to modi ed noise data and cumulated margins in certain cases. In addition, numerous additions and withdrawals in individual eets lead to changes in the value ranges reported. Grouping of aircraft types according to MTOW (maximum takeoff weight): under 50t 50 to 150t more than 150t This division generally corresponds to a grouping of regional, continental, and inter- continental aircraft 4U = Germanwings CL = Lufthansa CityLine EN = Air Dolomiti EW = Eurowings LH = Lufthansa, Lufthansa Cargo LX = Swiss OS = Austrian Airlines WK = Edelweiss Air New ICAO Chapter 4 limit, which has been effective for new aircraft since 2006: –10EPNdB when compared to Chapter 3.
