The aim of the research activity is to define some parameters of a Monte Carlo campaign for the simulation of an aeronautical vehicle. In particular, a procedure must be identified to determine parameters such as the minimum number of runs necessary to validate the results. This validation occurs as a function of the accuracy or error of estimating the average value of the desired probability distribution. The procedure must be parameterized based on the characteristics of the simulation, for example the number of random variables present in the simulation. The procedure must be supported by an analysis of existing solutions in the literature.
