A computer-based geometrical model of the Lak-17a sailplane was generated with the program AVL (Athena Vortex Lattice), which is designed to analyse the characteristics of flight and to provide a rapid analysis of the configuration of an aircraft. Various characteristics of stability and control were calculated by simulating a real flight with the program. According to the results, a conclusion was formulated and suggestions about how to improve the stability and control of the aircraft were offered.
