Modern aircraft are distinguished by the extensive use of automation facilities for piloting control – a "glass cockpit". At the same time, the widespread use of automation in the aircraft flight limits the pilot's abilities to overcome force majeure circumstances arising in-flight. Subsequently when training pilots, particular emphasis must be placed not only on the formation of the operator's skills in the "glass cockpit" but also on the development of practical skills while "direct" piloting, what is especially important. Large focus should be put on the requirement to train military pilots with the implementation of large values of normal overload, taking into account the increasing maneuverability of fighters from generation to generation that are flown not based on the capabilities of the airframe design and power plant, but considering the psychophysiological human abilities. Limit modes, in particular, performing high angles of attack with a subsequent stall, entering a spin cause aviation accidents in both civil and military aviation. As noted in the findings of the investigations, insufficient skills of the flight crew for piloting in critical modes are referred to the reasons for these accidents among other things. It is clear that the flight performance of the training aircraft, on which the future pilot takes the initial training course, serve the primary purpose of forming flight skills. Until recently, outdated aircraft, in particular L-39, as well as foreign-made aircraft (DA-40, DA-42, etc.) were used in our country for this purpose. The new domestic training aircraft with a propeller-driven power plant Yak-152, which made its maiden flight in September 2016, is designed to ensure the required high level of initial training, including safe piloting training in critical flight modes in the "glass cockpit" interface. The article analyzes the main characteristics of the Yak-152, directly impacting the capabilities of its intended use as a training aircraft. It should be noted that all the performance presented in the article was obtained as a result of aircraft flight tests.
