### HideShow timer Statistics

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?

(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.

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.
==> This will prove advantageous to Noetheren Air.
(B) Aviation fuel is projected to decline in price over the next several years.
==> If Aviation fuel is projected to decline in future, Skybus' will still be advantageous though not as much as when fuel prices remain constant or increase. Morever, Skybus' give advantage of reduced time spent on refuelling.
(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.
==> Same as A.
(D) None of Northern Air’s competitors that use Belleville Airport are considering buying Skybuses.
==> If none of its competitors are considering buying Skybuses, It will benefit Northern Air as it can increase customers by reducing the ticket prices.
(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.
==> This is the answer. If Skybus causes other plances to get delayed, number of flight that can take off in a day will reduce casuing revenue loss to the company.
OA and OE will follow later.

IMO E.

The delay in next flight might affect the schedules of other Northern Air flights, which is known for its quick turnaround, and thus will result in possible loss of business of the company.

(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. ---> Elimination of refuelling and job-cuts will actually be advantageous for the airline company.

(D) None of Northern Air’s competitors that use Belleville Airport are considering buying Skybuses. ---> This does not mean that the decision of Northern Air to use Skybuses is a wrong one. Discard this option.

(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. ---> Correct. The delay caused by Skybus' turbulence will impact Northern Air because we know that the airport is highly congested. This delay, will thus, affect Northern Air's quick turnaround time.
-----------------------------------

My choice will be option E.

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.

Hello Eski,

As you mentioned, reduction in fuel prices causes the final outcome to become advantageous to Northern Air. So, it does not pose any disadvantage for Northern Air. However, in case of statement E, the increase in turnaround time is actually disadvantageous to Northern Air as the company depends on low turnaround time. An increase in turnaround time might suggest that the company might face trouble in certain situations and might get into a fix. Hence, this is the answer.

Hope this helps! Let me know if I can help you any further.

I have a STRONG disagreement on the OA . Can some expert comment (as to why) , my reasoning is wrong.

The stimulus is :
Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economyand 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

so its about finding the new proposal to increase ECONOMY or/and to increase TURNAROUND TIME.

ANS:

(B) Aviation fuel is projected to decline in price over the next several years.
Here , the economics is clear. If the fuel prices are reduced , the profits increase . Howmuch , is debatable , but it WILL be ECONOMICAL

(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.
It will increase the congestion is true , but assume that the next fight is not of N-Airlines even then the congestion will increase . so it increase turnaround time OF ALL AIRLINES at the airport. Howmuch , is debatable , but it WILL increase TURNAROUND TIME

now consider both the arguments , how do we consider which one is more weighted ?

Can some expert advice , what is the GMAC trick here ? Have I misunderstood the reasoning?

IF it delays the other flights, then a chain reaction will follow which is really bad for the company's strategy!

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!

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.

Found it a bit easy. Just re-read to make sure there was no catch.

Kept B as a contender but any way even with the reduced fuel prices the aero-dynamic design would save the input costs

Will go with E

Hi icandy,

What I deduced from economy is a careful, thrifty management of resources. You're right in saying that the question is actually trying to say 'economical' by using the word 'economy'.
