Numeryczne i organizacyjne aspekty obliczeń stateczności samolotu

In the paper many sides to the computing of stability are considered. It is shown that from point of view of the time and the cost of computations it is advisable to join the equations of motion with a ``fixed point'' of the aircraft. Also it is advisable to project these equations on the stability axes (i.e. axes, which are connectcd with the vector of undisturbed flow). An advantage of usage of the stability diagrams in the design modification is mentioned.
