A. The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling.
-> Actually strengthens the argument.

B. Aviation fuel is projected to decline in price over the next several years.
-> A decline in price would still increase the profit margin and hence this as well strengthens the argument.

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.
-> Seems irrelevant, though I am not sure about this one.

D. None of Northern Air's competitors that use Belleville Airport are considering buying Skybuses.
-> Not all competitors could be flying as many flights to as far locations in order to actually gain profits. Irrelevant

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.
-> My choice of best answer. Delays in take offs will not be acceptable to any airport authority and hence Northern Air will face opposition.

I do chose E but I am skeptical about it. C too could be disadvantageous for the plan. If in GMAT, I would chose E anyways.

souvik101990, do post OA and OE once the time is out.

E is the only option that hinders the company.
If E was true, than the company would have to pay compensation to the other companies and these compensation would have offset to some degree the savings achieved by the fuel efficency

This is definitely a strengthen-weaken question, and E is definitely the answer:

A is a definite advantage
B cannot be a disadvantage; at worst it makes an advantage smaller than it otherwise would have been
C is only a disadvantage if the lost jobs generates enough bad publicity to affect the company negatively; this COULD lead to a strike and a shutdown of the airline industry etc but is highly unlikely given what an advantage this will be to the customers
D is absolutely irrelevant
E looks irrelevant - why would we care any more about the other planes than the mechanics we're about to fire - until you realize that some of these planes may be Northern's own planes, which COULD be a disadvantage if it increases turnaround time

No it is not a 700 level CR question. It is more likely to be sub-600.

It has gotta be E. Reason: The first sentence in the passage mentions that there are as it is "dozens" of flights of Northern Air. Later in the passage there is mention that these are smaller. A small assumption would mean that the number of flights of Northern Air will only increase.

Therefore, if that happens and the planes behind each Skybus are going to get delayed during take-off, several of those could well be Northern Air flights, which would ultimately result in a drop in profitability owed to slow turnaround.

Awesome explanation, that assumption is very much required here. If Skybus is going to take too much time in taking off then it will impact other northen Air Flights. Time = revenue loss. Kudos!

Conclusion: Replace planes with skybus - advantage to N.A(northern aviation)
Premise 1: NA uses a congested airport
Premise 2: NA depends on the economy and quick T.A.T

We are looking for an answer that weakens the conclusion that "replacing planes with skybus will be advantageous to N.A"

(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. - Does this weaken the conclusion? NO - This means NA can use skybuses to connect more destinations - more profit.Advantageous

(B) Aviation fuel is projected to decline in price over the next several years - Does this weaken the conclusion? NO - This means NA can use low fuel prices with skybus's aerodynamic design to make more profits. Advantageous

(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 job - Does this weaken the conclusion? NO - This means NA will have more success with even more quick turn around. We are not concerned with mechanics losing their jobs. Also, several could mean 10,100,1000. Not something we can use to assess whether or not the economy will be affected. This is an out of scope answer

(D) None of Northern Air’s competitors that use Belleville Airport are considering buying Skybuses - Does this weaken the conclusion? NO - NA will have an advantage.

(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. - Does this weaken the conclusion? YES - Since NA relies on its quick turnaround it means there could be several NA flights departing one after the other. If Skybuses cause turbulence and delay the next flight which could very well be another NA flight, these delays can be detrimental to NA. Their quick turn around time might be affected hence this is a disadvantage. Note that this is not the most apparent answer and does not demolish the conclusion but it is definitely the best answer.

Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, the novel aerodynamic design of which is extremely fuel efficient. The Skybus’ 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 its large planes with Skybuses?

Premise 2:Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, the novel aerodynamic design of which is extremely fuel efficient.

Conclusion :The Skybus’ fuel efficiency results in both lower fuel costs and reduced time spent refueling.

A is a strengthens the conclusion
B also strengthens the conclusion
C is not relevant
D is not relevant
E bingo this our answer as skybus delays other planes that take off after skybus takeoff what if those planes are of northern air

The passage presents some facts about Northern Air’s business-in particular that its success depends on quick turnaround and economy.
TURNAROUND (Exact Meaning) : the process of readying a transport vehicle for departure after its arrival; also : the time spent in this process.

Also, I need to mention a point about the economy here,as some of my friends have asked questions earlier in this thread related to economy,
this is not "economy" in the sense of a nation's overall economy; this is "economy" = "reduction of costs"/"value for money". here, that reduction of cost will be by using fuel efficient planes, thus saving on fuel costs.

The airline plans to promote these goals by purchasing Skybuses, which will reduce fuel costs and time spend refueling. The question asks you to identify a disadvantage for the airline in this plan.

Detailed Explanation for the options -

Choice E is the best answer because from the passage we know that Belleville Airport is highly congested and that Northern Air has many flights into and out of this airport daily. Therefore, the delay that Skybus takeoffs cause for other planes will impact Northern Air‘s flights, reducing the airline’s ability to achieve rapid turnaround.

Choice A and C are incorrect since the ability to have more destinations served by direct flights (choice A) and to eliminate refueling at some destinations (choice C) are both potential advantages of Northern Air’s plan.

Choice B is incorrect for the reason that although a decline in the price of aviation fuel would reduce the cost savings from introducing the Skybus, a reduction in fuel costs would still be an advantage, although a smaller one.

Choice D is incorrect. The simple fact that Northern Air’s competitors are not considering buying Skybuses does not itself present either an advantage or a disadvantage for Northern Air, although the reasons the competitors might have could include both advantage and disadvantage.
