Legal Definitions - national airspace

Definition: National airspace refers to the space above a nation's territory, including internal waters and the territorial sea, over which it has complete and exclusive sovereignty. It is the area where aircraft can fly without violating a country's airspace laws.

• A military drone flying over the territorial waters of a country is in the national airspace of that country.

The examples illustrate that national airspace is the area above a country's territory where aircraft can fly without violating any laws. It is important for countries to have control over their national airspace to ensure the safety and security of their citizens.
