The echelon usage control of helicopters is one of the most import job in the aviation equipment support，aiming at the difficulty and lack of evaluation index in the echelon usage control, two methods of the echelon usage control are introduced, the way of echelon optimization control technology is mainly expatiated, the influences of different parameters in the echelon usage control are deduced and analyzed, and the evaluation indexes of echelon usage control are presented. Finally, a case study is carried out by using the method of echelon optimization technology, the results indicate that the method is more intuitive and more comprehensive than the ladder diagram method, and the evaluation indexes proposed are reasonable, and the research direction of the next step is clarified.
