Abstract: With the rapid development of civil aviation in China,the shortage of pilots has become a constraint to airlines.When implementing a monthly flight plan,it will be constantly adjustedfaat is affected by various reasons.As a result,the investment of pilot resources in the first three weeks is usually so much that there aren't enough pilots left for the flight task at the last week in a month,and the pilots' flight task arrangement is always tight.In this paper,a methodology of tightness evaluation of captains to accomplish the flight tasks of the last week in a month is developedfor this problem.The method takes the weekly flight task as the research object,and classifies captains into three classes by their flight time.Then,the relationship between the weekly flight task and the amount as well as the structure of pilots'investment can be developed.Therefore,the amount of the pilots needed and the personnel structure corresponding to the distribution of the pilots'flight time of the last week in a month can be forecasted,and the tightness can be evaluated.Consequently,we can alarm timely and ensure smooth accomplishment of scheduled flight,as well as reasonable allocation of flight training resources.
