Abstract: The fresh new traits that new equipment possesses, such as the high complexity of complex equip-processing, the multiformity of the equip-used environment, the coupling characteristic of the human-equipment-environment factors, and the dynamic idiosyncrasy of risk, bring huge challenges to the safety analysis and evaluation. According to the characteristics of a complex system, such as hierarchy, structure, and complex operating environment, this paper analyzes and depicts the state evolution process of equipment from hazard symptoms to accidents under the influence of initial events (faults, human errors, etc.). At the same time, the parameters representing the concept of safety distance are put forward to effectively control the time. Combined with a certain abroad type of carrier-based aircraft landing process, the landing process safety analysis model is established to verify the applicability of theoretical methods. Through simulation, the hazard modes and their relationship with effective control time are analyzed and the safety constraints model of the landing process is established.
