The article describes the results of an analysis of the states and operating conditions the ASz-62 IR-16E engine. The tests were carried out on an AN-2 aeroplane with the ASz-62IR-16E engine. The purpose of this study was to determine the contribution of static and dynamic engine operating states during flight. The engine operating parameters were recorded at a frequency of 16 Hz for over 7 hours of flight. The engine operating points defined by two parameters, i.e. engine speed and intake manifold pressure were analysed, and the mean values, standard deviations and histograms of the distributions of these parameters were determined. The distribution of the occurrence of various operating states, i.e. steady states and transients was also analysed for low, medium and high load, and for IDLE and WOT. The article describes the contribution of the individual engine operating states to the total flight time. The results obtained for the aircraft engine are compared with those obtained for automotive vehicle engines and described in the paper. The study shows that most of the operating time of the ASz-62IR-16E aircraft engine was in steady-state conditions - about 90% of this time, whereas steady-state operating conditions for the automotive engine account for about 80% of the driving time. For the aircraft engine, more than 65% of operating time is heavy load. Small and medium loads account for 10% and 25% of operating time, respectively. In the case of the car engine, only about 5% of operating time is heavy load, while the major part of operating time is under light (about 40%) and medium (about 55%) load. Under idling conditions, the aero-engine's operating time was about 6.2 %, i.e. about twice shorter than that of the car engine (about 13.2 %). Under WOT conditions, the aircraft engine had an operating time of 1.3 %, while for the car engine this condition was extremely rare - about 0.1 %. It was also shown that the ASz-62IR-16E aircraft engine of the AN-2 aircraft in real flight conditions has a specific, most frequently used operating point lying in the range of the values: n=1800÷1900 RPM and MAP=0.8÷0.95 Bar.
