in law, the atmospheric expanse over the land and water territory of a state. It is under the sovereignty of the state and is part of its territory. The border of the airspace is a plane perpendicular to the land surface extending along the line of the land and water borders of the state. The altitude limit of the airspace is not defined.

The extension of the state’s sovereignty over its airspace is formulated in multilateral and bilateral international agreements, as well as in the internal legislation of the state. Sovereignty over the airspace means complete and exclusive authority of the state within its airspace: all flights of foreign aircraft within the airspace can be made only with the con-sent of the state in question and in accordance with the laws and rules established by it (such a consent is usually formulated in a bilateral or multilateral international agreement). While within the airspace of a state, a foreign aircraft to some extent falls under the jurisdiction of this state (including the obligation to observe passport, customs, sanitation, and other rules).
