PrepTest 103 - Section 2 - Question 10

Show summary

Commercial passenger airplanes can be equipped with a collision-avoidance radar system that provides pilots with information about the proximity of other airplanes. ███████ ███ ██████ █████ ██████ ██ ████ ███████ ██████ ████ ██ █████████ █ ████████ ██████████ ██████████ ███ █████ ██ █████████ ████████ ████ ███ ██████ ████ ██ ██████████ █████████ ███ ██ █████████ ████ ██████ ███ ██████ ██████████ █████ ██████ ██ █████ ███████ ██████████

Summary

The argument concludes that passengers are safer on airplanes with a collision-evasion system equipped, even though the system frequently warns pilots of phantom airplanes. This is supported by the premise that the system warns pilots to evade possible collisions.

Notable Assumptions

The argument assumes that the phantom warnings don’t create more danger than the system prevents. For example, that pilots don’t take dangerous evasion maneuvers in response to phantom warnings.

It also assumes that pilots actually respond to the system’s warnings frequently enough to avoid possible collisions. Otherwise, the system’s presence wouldn’t make much difference to safety at all.
