Environment Cost Index för Boeing 737
Sammanfattning: Globally, aircraft emissions represent 2-3% of total CO2 emissions. Due to an increase in passenger and freight transport, the climate's impact is increasing. To solve that problem there are several different solutions, one of them is the use of an optimal cost index during flight. The purpose of this work is to analyze the cost index and its shortcomings and to develop solutions to create an Environment Cost Index. ECI contains strategies that make cost index more optimal with focus on environment, fuel consumption and emissions. However, this thesis only deals with the Boeing 737-800 (winglets) aircraft type. The work process began with a wide search of current climate problems and aviation emissions, with a deep search in cost index and previous studies on the subject. In order to link theory with reality, an interview was conducted with Lars Andersen Resare, SAS Sustainability Manager. The result showed that the theory is in line with Lars Andersen's answers. In addition to different strategies that can be followed during the flight to reduce fuel consumption, the ultimate solution is a dynamic module. A dynamic module has all sources packed in a system and updates the pilot with information during a flight, as the system is connected to the network. With an ECI, airlines can save 5-6% fuel during one flight. As an airplane is often in the air, the strategies give an environmental gain, as well as a saving up to 5 million dollars a year, without noticeable changes in the timetable. As the aircraft emissions increase every year, and the FN Climate Panel has set a goal to zero the growth of carbon dioxide emissions by 2050, ECI is one of the solutions that reduces the climate impact. It would therefore be of great benefit to both environment and costs if the airlines used the tool.
