Questions Question 14

In older commercial airplanes, the design of the control panel allows any changes in flight controls made by one member of the flight crew to be immediately viewed by the other crew members. In recently manufactured aircraft, however, a crew member’s flight control changes are harder to observe, thereby eliminating a routine means for performing valuable cross-checks. As a result, the flight crews operating recently manufactured airplanes must inform each other verbally about flight control changes much more frequently.

Summary

In older commercial airplanes, flight crew members could immediately see changes made in the plane’s flight control panel. However, in newer airplanes these changes are harder for crew members to see, therefore eliminating a means for cross-checks. As a result, flight crews operating newer airplanes must verbally inform each other about control panel changes much more often.

Strongly Supported Conclusions

The frequency flight crew members must talk to each other about changes to a plane’s flight controls depends on what other means for communicating these changes are available.

A

How frequently an airplane’s flight crew members will inform each other verbally about flight control changes depends in large part on how long it takes to perform those changes.

This answer is unsupported. We don’t know from the stimulus how long it takes for crew members to make any changes to a flight’s control.

B

In recently manufactured aircraft, the most valuable means available for performing cross-checks involves frequent verbal exchanges of information among the flight crew members.

This answer is unsupported. We don’t know from the stimulus whether the crew talking amongst themselves is “the most valuable means available” to them. There could exist other methods that weren’t mentioned and are more valuable.

C

In older commercial airplanes, in contrast to recently manufactured airplanes, flight crew members have no need to exchange information verbally about flight control changes.

This answer is unsupported. We don’t know that crew members had no need to talk to each other in older airplanes. We only know from the stimulus that in newer airplanes, crew members must talk to each other more often.

D

The flight crew members operating a recently manufactured airplane cannot observe the flight control changes made by other crew members by viewing the control panel.

This answer is unsupported. We only know from the stimulus that, in newer airplanes, changes to the control panel are harder for crew members to see. Harder to see does not imply that these changes are impossible to see.

E

How often flight crew members must share information verbally about flight control changes depends in part on what other means for performing cross-checks are available to the crew.

This answer is strongly supported. The change in crew member’s ability to directly see changes in a flight’s control panel caused the crew members to talk with each other more frequently.

Cookie Cutter Review
Weakening question with causation argument where (B) offers counter evidence where the supposed effect precedes the supposed cause. (D) is wrong but it's wrong in a cookie cutter way. Lots of trap answer bait you to make assumptions. (D) baits us to assume that hand dexterity is important for making sophisticated tools. There is zero evidence that's true and so it is an unwarranted assumption.
