### 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, 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.

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.

(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.

I understand the reasoning for E in that future flights will get delayed that will hamper the turnaround time.

But the argument mentions "Northern Air depends for its success on economy and quick turnaround "
In C it is mentioned "several mechanics would lose their jobs". Does this not hamper the economy?

or am I exaggerating too much here. Any help is appreciated
Thanks

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.

They mean economy as in economical running i.e. cheaper running costs. Not the economy of a country. So if anything, that would be an advantage.

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?

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.

OOps , I got that . I got trapped . BTW just for the info , ANY CR question will have following traps :-

1. Hyped - Exaggerated information , it might be right but its blown out of fact. These are just the extension of stimulus , but with exaggerated words.--most critical
2. Extension of stimulus . Classic trap
3. Redundant - Irrelevant , might be critical for 'it true' questions type , in these cases it can be 2nd option
4. Opposite - if asked for supporting the assumption , it goes against it . Classic trap , almost always present

Acronym is "HERO"

If I miss something lemme know

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

E is the only choice. Other options are very direct. Is this a 700+ level question ? I seriously doubt about it.

Agree with E same reasoning one flight will delay the other flights also and it will go on and on.

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!
