118. 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.
B The decline in the price of aviation fuel might make the plan seem less pressing, and it could conceivably complicate the issue of whether the expected savings would justify the investment in
new planes. However, lower fuel costs would not diminish the crucial time-saving advantage of Skybuses, and any hypotheses about their relevance to the overall decision are purely speculative.
C The ability to eliminate refueling is an advantage to the airline. The loss of jobs could, in theory,
have some negative effect on the airline due to lowered morale among remaining employees.
However, several does not support a hypothesis that the effect would be very significant, and any hypotheses about whether it might override the benefits are purely speculative.
