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

摘要

Based on the customers' environmental awareness rising globally, nearly every aeronautical 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 common 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 fleet evolution based on the current traffic growth predictions. Basically the requirements in these documents are set without accounting for the way of how to achieve them. Even though aircraft development 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, subsystems 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 fleet model and the world fleet composition until 2030 from todays standpoint. The paper closes with a discussion about innovation in aeronautics and the elements needed to foster it.
