Which of the following is NOT a function of the Federal Communications Commission?

The Federal Communications Commission (FCC) is primarily responsible for regulating interstate and international communications by radio, television, wire, satellite, and cable across the United States. This includes functions such as granting broadcasting licenses, creating rules for broadcasting behavior, and enforcing rules for telecommunications, all of which are within the domain of the FCC.

However, regulating aviation safety falls outside of the FCC's jurisdiction. Aviation safety is primarily managed by the Federal Aviation Administration (FAA), which oversees all aspects of civil aviation in the U.S., including air traffic control, aircraft safety standards, and pilot certification. Therefore, the choice that identifies a function not under the FCC's purview accurately reflects the division of responsibilities between these two agencies.
