Abstract: Mission Completion Success Probability (MCSP) is one of the important reliability targets Used in military aircraft design. It should be predicted repeatedly. It is the first time in our country that the airplane .mission reliability, is predicted. This paper presents a MCSP. prediction method for military trainers. This method is derived from engineering practices. The characteristics of Mission Reliability Diagram are represented systematically. A mathematical model used in MCSP Calculation of military trainers is presented.

Key words: military krainers, mission reliabilitq, prediction process
