### 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.

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?

My Explanation:
-----------------------------------
(A) The Skybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling. ---> This would rather prove to be advantageous for the airline company.

(B) Aviation fuel is projected to decline in price over the next several years. ---> This will again prove to be advantageous for the airline company as the decrease in price along with the Skybus' inherent fuel effiecient feature will overall reduce the cost of operation.

(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.

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

I just dont get the above. Is the Q trying to say economical instead of economy?

quick turn around of what??

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'.

Technext

Wow! I travel frequently, almost 50%. I never heard of the word quick turn around for the activities referred here. Was not much helpful to me. Thanks for sharing your thoughts.

icandy,

Are you going to apply to an onlime MBA program since you travel so much?

just curious

why cudn't d ans be A.

the airlines can get more passengers whr it haults its planes for refuelling.??
where as for the option E, its not necessary that the planes flying subsequent to the SkyBus are northern airlines planes.

as the question asks abt the profit perspective of Northern Airlines, i guess it cud b A.

Its true that airlines could carry more passengers when they stop for refueling.
But, you are making an assumption that the flights which stop for refueling are NOT full.

Planes flying subsequent to the skybus are northern airlines planes.
Argument mentions that Northern airlines flies dozens of planes.

A: expected to engage routes that require stoppages for refueling- advantage since Skybus needs cheap fuel and refuels at minimal time. Thia option is actually an advantage.
E: turbulence causes delay to other planes.... Disadvantage....CORRECT.
