The combat capability of the air force and the flight of fighter and transport aircraft are highly dependent on the presence of ground support systems. The resence of a large number of ground support systems in aircraft repair centers and overhaul centers for heavy repairs indicates the existence of deficiencies in maintenance and repair methods. Aircraft ground support equipment has always faced the problem of increasing maintenance and repair costs, and the statistics of ground-based aircraft support systems have an upward trend, which is now looking for a solution to control the current situation. the Purpose of this study is to explain how to optimize the maintenance method of aircraft ground support systems in nahaja. and the main research question: optimizing the maintenance of aircraft ground support systems in nahaja how should it be? which is based now the type of applied research and the method of doing it are descriptive and intergrated with the approach. The statistica population of the study includes all expert commanders and officials of the aircraft ground support equipment department in nahaja units, which is a factor of 120 people. at a significance level of five percent, the accuracy of the research hypotheses is constrained. the innovation of this research is counting and extracting instrutions for using aircraft ground support systems, improving the scheduling process of using equipment.
