Description: In the article offered methodic the estimation reliability prognosis of exploitation radio electronic equipment at during of avionics on the state with control of parameters. A methodic is based on the vehicle of canonical decompositions of casual sizes. The prognosis is carried out in three stages. Above all things, canonical decomposition of a priori is made probed process. After statistical treatment of the got casual coefficients of canonical decomposition the design of a posteriori process is carried out. On the got realization of posteriori process the prognosis of reliability settles accounts on the method of Monte Carlo.
