The operational capability of meteorological service plays a crucial role in civil aviation.Based on the characteristics and process analysis of meteorological operation in civil aviation,an index system based on systematic idea is established from four aspects,namely human resource,equipment,law & regulations,and environment.We also design an assessment procedure and develop the evaluation system of meteorological operational capability in civil aviation service.The reliability and rationality of the index structure in this evaluation system is confirmed through system testing and trial operation.The system application results show the difference between the actual operation state of the evaluation target and the related standard specification,thus provide reference and direction for improvement of the evaluated entities.The statistic and analysis function of the evaluation system can provide comparisons between different evaluated entities or different evaluated items.The evaluation system will avail the improvement of the meteorological operational capability in civil aviation,increase its ability to deal with complex weathers,and ensure the meteorological service quality.
