摘　　要：从市场需求研究民用客机设计服役目标,包括飞行小时、飞行起落和飞行年限等。通过目标市场退役年限获得飞行年限,通过短程、中程和远程典型航线距离获得飞行长度,再依据飞行长度、飞行次数、日利用率之间的统计关系获得飞行循环与飞行小时。对得到的数据进行分析得出结论:自2000年以来全球飞机退役年限和飞行次数呈下降趋势,而日利用率呈上升趋势,即飞行长度和平均航程呈上升趋势。最后以宽体客机亚太市场为例验证该方法。Based on the market requirement, a method to decide a civil passenger aircraft design service objectives that include lfight hour, lfight cycle and lfight year was provided. According to the market retirement age, the lfight years was calculated. Based on short, middle and long typical routes, lfight length was gotten. Then according to the relations between lfight lengths, lfight times and daily utilization, lfight cycles and lfight hours were gotten. After analyzing the data, the conclusions were summarized. Since the year of 2000, the retirement age and lfight cycle has been going down, while daily utilization and lfight length is going up. At the end, with wide body aircraft used in Asia Paciifc market as an example, veriifed the method.
