Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus’s fuel efficiency results in both lower fuel costs and reduced time spent refueling.
Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?
(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. (B) Aviation fuel is projected to decline in price over the next several years. (C) The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its destinations, but several mechanics would lose their jobs. (D) None of Northern Air’s competitors that use Belleville Airport are considering buying Skybuses. (E) The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeoffs.
首先kEY point: Northern Air depends for its success on economy and quick turnaround 问题是问Which of the following situation could could present the most serious disadvantage for Northern Air 除去那些没谱的我只说B和E B) the decline of aviation fuel certainly is a serious disadvantage to the airline, why? because the airline supposedly spends huge investment for achieving one fuel cost reduction two less fueling time. if the reduction of fuel price is lowered enough, the airline is better off by not changing its fleet to skybus. Suppose the airline did change to skybus, the cost of investment might not be covered from the switch, since fuel cost reduction diminish or no longer provides investment return. on top of that, lets talk about advantage, personally, i think advantage is a relative term used in describing something in which a competitor does in order to create a advantage that its competitor does not have by not doing something. E) says airport would be disturbed by the new airplane's takeoffs, subsequently hamper the airline's quick turnaround, thus constitutes a serious disadvantage. I disagree, why? because the competitor's are using the same airport, the consequence of using skybus would be felt by every competitor, therefore no one is better off at all, every competitor suffered equally in this situation. how can you say this is an disadvantage to Norther Air since the affect of the action is shared equally to every other competitor?
sorry about my poor grammar and all that, I just can't seem to agree with the OG explanation. 作者: xyolandas 时间: 2012-11-7 23:00
我做这题时候也有个疑惑 难道一个公司的飞机是连着起飞的吗 喷出来的气流影响别的飞机怎么了。。。作者: 潇水若木 时间: 2012-11-8 10:04
我觉得这个B你想多了···B说油价要降了，但是降到什么程度？ 你说换飞机费用高，但是高到什么程度？注意看你这句话“Suppose the airline did change to skybus, the cost of investment might not be covered from the switch, since fuel cost reduction diminish or no longer provides investment return。” 你说是有可能，就是不确定，也就是有很大可能换飞机从长远来看还是合算的，原文没有告诉油价涨幅，飞机有多贵，所以这个不能随便suppose的··想多了不好的。
再看D"I disagree, why? because the competitor's are using the same airport, the consequence of using skybus would be felt by every competitor, therefore no one is better off at all, every competitor suffered equally in this situation. how can you say this is an disadvantage to Norther Air since the affect of the action is shared equally to every other competitor? " 楼主啊，谁告诉你关于competitor的事啊？谁说的竞争者也用同一个机场啊，全世界的都用一个机场吗？ 而且原文说Northern Air depends for its success on economy and quick turnaround ，拼的是什么，拼的就是高turnaround啊，如果说用换灰机后turnaround不行了，那肯定disadvantage. 做逻辑题千万不要想的太多啊，题目没告诉的就是没告诉，不能根据太多自己的知识来判断的····· 第一次回，说得不好，多多指教作者: slgbond 时间: 2012-11-9 00:25
B 油价高决定，公司换飞机，那卖省油的飞机，这个逻辑是对的，
但不清楚剩下的油钱和换飞机那个钱多，说明这个推理对但有明显有漏洞
E 其实关注点在，造成其他航班延误了，这个是航空公司要考虑的吧，没什么漏洞吧？ 换飞机应该更准点啊，怎么反而造成其他飞机延误呢
