Abstract

Analysis of flight accidents of sports aircraft suggests that their main cause is the loss of control and, consequently, collision with the ground due to errors made while performing aerobatics. To ensure the safer performance of aerobatic maneuvers, it is not only important to establish safe entry speeds into these maneuvers but to also determine the consequences of possible errors in following parameters during the start of the maneuver: the required altitude, the entry speed, rate and range of control surface deviations. This research paper presents the probabilistic characteristics of piloting errors and model studies of changes in speed and altitude when performing a dive and Split-S on a Yak-55M aircraft, and the cases of normal and late recovery from the Split-S maneuver with the use of various tempo and the magnitude of the control surface deviations. The results show the initial approach to the development of safety requirements for an aerobatic flight of sports aircraft.
