An aviation treatment of agricultural and forest lands has advantages as against at-ground one on productivity, opportunity to cultivate a field with the humidified soil, to lack of mechanical damages of plants. The authors proved expediency of use of a light aircraft for chemical operations. A gyroplan is perspective easy rotary-wing aircraft for application of liquid products of chemicalixation. It hass properties of a plane and a helicopter. Developed by authors gyroplan has a modular design of the apparatus providing the automated application of liquid producs of chemicalixation with a operating speed of 70-100 km/ha and spreading width of 8 m, high of 1.0-1.5 m, application rate of 10-20 l/ha. Parameters of efficiency of use of the autogyro were established: duration of one flight cycle depending on length of furrow and distance of approach to the cultivated field site; useful loading capacity and application rate. The field area processed by the gyroplan increases with reduction of norm of application which rational values make 10-20 l/ha. With increase in useful loading capacity from 100 to 350 kg gyroplan productivity in flight hour increases by 3 times and more. However, loading capacity is limited by the power of the plantpropulsion unit of an autogyro. The shotest time of flight of an autogyro is 14-46 min and the maximum efficiency of treatment of crops is 37-43 ha/h. These parameters are provided at rational values of length of furrow of 1.0-2.6 km within approach distance to a field of 0.6-1.5 km. For example, if an engine capacity of the plantpropulsion unit of an autogyro equals 150, 200 and 300 h.p., so useful loading capacity usually makes 120, 200 and 350 l respectively.
