Analysis of direct operating cost of wide-body passenger aircraft: A parametric study based on Hong Kong

Analysis of the Direct Operating Cost(DOC) of aircraft is an important step towards achieving financially sustainable aviation operations. However, the value of the DOC for different aircraft types and flight scenarios is not widely available. In this study, we perform a systematic analysis of the DOC of every wide-body passenger aircraft currently in production, using the method of the Association of European Airlines(AEA). The elements of the DOC, e.g. financial costs, maintenance costs, and flight costs, are evaluated individually. Several realistic flight scenarios are considered, each with differences in route distance, fuel price, passenger number, and seating arrangement. For each flight scenario, the most cost-efficient aircraft type is identified and evaluated in the context of operations from Hong Kong International Airport. The information provided in this study could be useful to airline operators and policy makers.

一抹清新色

2月，除了气温略有浮动，深圳这座城市在颜色上似乎没有一点变化。马路旁紫红色的筘杜鹃依然开得欢腾，城市绿廊也还是小草青青、生机盎然。都说南方没有秋天，没有见到日渐萧疏的秋林和漫天飘落的黄叶，好像一阵冷风拂过，就这样捎给了我们下一季的消息。南方没有北方那么长时间的季节过渡，相应地也略过了自然中很多烂漫鲜活的色彩。
