ABSTRACT
This article aims to find the main causes of landing related accidents and search for the possible precautions which could reduce the number of accidents. As for the light sports aircraft category, the accidents occurring during the landing phase represent from about 20% to 30% of all accidents recorded. The number of landing related accidents is relatively stable despite the efforts to improve this. The main cause of these accidents is pilot error. It is not usually investigated how these pilot errors occur and if it is possible to prevent them. Therefore, in presented article, investigations of 112 ultralight aircraft accidents and 152 GA aircraft accidents recorded in the Czech Republic from 2005 to 2015 were performed. The main gal was to find the causes of pilot errors in order to identify the common features of the accidents. A significant error rate associated with the pilot height estimate during flare was identified, therefore the possibility of improvement was investigated by adding an acoustic altitude signaling during flare.
