Definition and Selection of Air Transportation System Requirements based on "a posteriori" knowledge

Abstract

Based on the customers' environmental awareness rising globally, nearly every aeronauti- cal institution came up with a road map for Air Transportation System (ATS) requirements considering a time horizon up until the year 2050. What all these documents have in com- mon is that they rarely take into account a historical view of the evolution of the ATS, the current situation of the system or a near term view of e.g. the world eet evolution based on the current tra�c growth predictions. Basically the requirements in these documents are set without accounting for the way of how to achieve them. Even though aircraft devel- opment follows an evolutionary trajectory there needs to be an incentive within the system to innovate. Instead of providing a global solution for the challenges mentioned, this paper intends to arouse interest for a more comprehensive view of the ATS, its stakeholders, sub- systems and interdependencies. After having a look at the system entities we will examine the current situation on the production site of air transport. Furthermore there will be an introduction to a world eet model and the world eet composition until 2030 from todays standpoint. The paper closes with a discussion about innovation in aeronautics and the elements needed to foster it.
