摘要:Implementing risk assessment is of great significance to aviation safety. At present, with the gradual assembly of large transport aircraft with troops, it has become an urgent matter to carry out reloading airdrop to achieve the desired combat purpose and effect. In this paper, the task process of reloading airdrop is described in detail, the risk evaluation index system is established by using the questionnaire, and the probability and severity of the evaluation index are scored, and the risk grade is determined according to the risk matrix. Finally, the fuzzy analytic hierarchy process is used for risk assessment, and the corresponding preventive measures are put forward. The evaluation results show that in the process of heavy load airdrop, attention should be paid to the possibility of aircraft instability during the process of equipment and materials delivery.
