AVSC 3400 International Flight Operations Practice Test

The main idea here is a specific legal right tied to operating transport services within a country. Cabotage refers to a nation’s control over transport that occurs between domestic points, including who may operate those domestic flights and under what rules. That makes it the best fit for describing the state’s ability to regulate air traffic within its own borders, since it focuses on the operation of domestic routes by carriers.

This differs from sovereignty, which is the broad supreme authority over a state's territory, including many facets beyond air traffic. It also differs from airspace control, which is about the actual management and separation of aircraft in the airspace, not the legal rights of carriers to operate domestically. Jurisdiction is the general authority to enforce laws within a territory, whereas cabotage is specifically about regulating domestic transport services and the carriers that operate them.

So cabotage is the precise term for the rights to regulate air traffic on domestic routes within a country, making it the best answer.
