The article highlights the main features of the training of flight personnel in fighter aviation schools during the period of radical change in the World War II East Front. The main components of the training of pilots are considered and analysed, such as – the system of recruiting the teaching and instructor staff, statistics of aviation accidents, the state of the airfield network and the material and technical base of educational institutions of fighter aviation, etc. The general patterns of fighter aviation schools were revealed, which manifested themselves in the loss of training time spent on overcoming everyday difficulties in places of evacuation.
