The aim of this project is to uncover some selected peculiarities and secrets of aviation and to explain them clearly to the reader. The points listed are limited solely to commercial passenger aviation, but cover various independent topics such as the cabin, the aircraft systems, the airline and many more. The depth of the elaboration of the respective topic depends significantly on the complexity of the same. Depending on the situation, visualizations in the form of figures, tables and graphics are used, and the simplest basic physical-technical knowledge is required. The explanation takes place in a scientific-theoretical and nevertheless entertaining manner. In total, 13 curiosities are analysed and subsequently assessed. The individual points which this thesis deals with were selected in such a way that in practice they arouse interest, but in part also incomprehension, and are usually not self-explanatory. The elaboration starts exactly at this point and breaks down the respective aspects. Starting with a basic investigation of the lift force, a decision is made in the further proceeding whether to attach winglets. This is followed by various topics, including aircraft windows, the primary structure as a Farady cage, but also tpoics concerning the cabin as the cabin air and oxygenmasks. Later, emergency procedures such as engine failure and fuel dumping are analyzed. The insight into potential future materials in aviation industry is followed by an outlook on autonomous flying after showing how dangerous the current trend towards longer working hours for cockpit staff is.
