Statistical evaluation and analysis of mutual interaction of components

Abstract

One of the most basic methods of reducing maintenance costs in civil aviation is discussed in this paper. This method, which is used by transport carriers, is a reliability programme. The parameters applied in this programme are described in case as they express the numerical evaluation of failure of aircraft components. Nevertheless, such evaluation permits to assess only the selected components. Other statistical methods must be used to assess the reliability of an entire technical system. For this purpose, a correlation and regression analyses are applied to analyse an entire aircraft system, and some results of this investigation are presented here.
