Balance 2015 ENG

Swiss has developed a new process to calculate the optimum arrival times of its long-haul flights in Zurich on a daily basis. Austrian Airlines‘ Fokker fleet has followed the modified takeoff procedure “1,000-foot acceleration” since June 2013. Lufthansa Cargo has five Boeing 777Fs in its fleet. The “Triple Seven” is considered the most efficient and quietest aircraft in its class. the latest data from the aircraft in flight and adapts it if needed. In this way Swiss con- serves 500 tonnes of kerosene per year and avoids 1,500 tonnes of CO2 emissions. The new method optimizes the assignment of time windows practiced so far in the context of the approach procedure “Greener Wave” (see page 72, Balance 2012) and received a Lufthansa Group Innovator Award in 2014. At New York’s John F. Kennedy Airport (JFK) Swiss developed ways to reduce the energy consumption and running times of auxiliary power units (APUs) during ground handling in the framework of a Kaizen workshop. The use of ground power units (GPUs) was extended for this purpose; a method that has already been successfully implemented at Zurich Airport. The insights gathered at the workshop are to become the basis for a new standard that can be applied at other airports as well. Austrian Airlines In Vienna the airport, air traffic control, Austrian Airlines and other carriers, as well as handling operators have coordinated their activities in the framework of Airport CDM (Collaborative Decision Making) for many years. Standardizing processes is aimed at increasing punctuality and reduc- ing fuel consumption. The Fokker fleet operated by Austrian Airlines has applied the modified takeoff procedure “1,000-foot acceleration” since June 2013. Optimized thrust reduction and acceleration conserve kerosene and thus reduce CO2 emissions. 48 // Climate and Environmental Responsibility
