Dynamics of a light aircraft in spin

This paper focuses mainly on the experimental and in-flight spin investigations for an executive light airplane, named I-23 and built in the Institute of Aviation (Warsaw, Poland). It is a single-engine, all composite, straight wing, retractable undercarriage, conventional configuration and flight control system airplane. In-flight spin tests confirmed good rudder and elevator effectiveness for spin recovery in a wide range of positions of the center of gravity. A typical time history of a spin entry and the developed spin and recovery is shown as well.
