Manned, fully electrically powered vertical take-off and landing aircrafts (eVTOL: electric Vertical Take-off and Landing) are often referred to colloquially as air taxis, although they are much more similar to small aeroplanes and helicopters than cars. After years of technical development and testing of prototypes, the first air taxis are now on the threshold of authorisation and commercial use. For this reason, six years after the publication of the first version of the brief topic profile (TAB 2018), the German parliament commissioned a new examination of the topic. The future utilisation prospects of regional airports were also to be considered. The previous version of the brief topic profile was modified and supplemented in the course of this update. The topic is particularly relevant to society as a sub-area in the context of a comprehensive need for mobility and the transport transition towards low-emission private transport. However, electrified, vertical take-off and, in the future, automated aircraft will most likely only represent a niche offering in premium markets in a future transport mix. Although it is to be expected that more and more eVTOLs will be on the road in the future, there are considerable challenges for successful operation. This primarily concerns regulatory issues, in particular aviation security and the regulation of air traffic. In Germany, these include the obligation to operate from an aerodrome. In addition, proof of economically viable operator and business models beyond prestige projects still needs to be provided. Environmental policy issues relating to new burdens (e.g. noise) arising in the course of "urban air mobility" also need to be clarified.
