Commercial Pilot License (CPL) Practice Exam

The concept that defines common carriage in aviation revolves around the transportation of passengers or cargo for compensation on a regular and scheduled basis. This includes the expectation of providing service to the public or any individual who wishes to utilize the transport system, thus ensuring availability and accessibility.

The correct choice reflects that common carriers engage in the transport of both cargo and passengers, which is typically accompanied by advertising to inform the public about available services. This aligns with the regulatory framework governing common carriers, as they are required to offer their services to any person or entity willing to pay the established fare.

In contrast, the other choices do not fully capture the essence of common carriage. While specific contracts (as mentioned in the second choice) might pertain to charter services or on-demand flights, they do not ensure regularity and public availability inherent in common carriage. The focus on freight exclusively in the third choice disregards that common carriers also transport passengers. The notion of requiring scheduling and rate filing in the fourth choice hints at some regulatory aspects but does not encompass the broader principle of serving the general public that defines common carriage.
