The publication presents an analysis of the operating conditions of the propulsion system of an ultralight autogyro during flights of various lengths and dynamics. This analysis is aimed at demonstrating the limits of variability of engine operation to determine the boundary conditions of aircraft engine operating conditions in actual operation. This parameter, in turn, will enable the effective use of the advantages of aircraft hybridization depending on the type of mission. The research data was collected from 10 different flights of the TERCEL wind turbine. MAP, RPM, flight altitude, horizontal and vertical speed, etc. were extracted from the on-board FDR (Flight Data Recorder) and then analyzed. The flights were classified as short SF (<30 min) and long LF (>30 min). The defined parameters are steady state and transient engine operation, IDLE, low load LL, high load HL and WOT as well as acceleration and deceleration. The analysis of the data shows that for the short flights, the share of steady state is about 80% and increases to more than 90% for the long flights. For the short flights, the share of acceleration accounts for about 60% of transient states and also increases to more than 65% for the long flights. For the short flights, IDLE, LL and WOT have a fairly significant share and amount to 32%, 36.1% and 7.5%, respectively, while they are increasingly marginalized by the increasing share of HL as the flight lengthens. For the long flights, HL's share was almost 70%.
