Airspace means the portion of the atmosphere controlled by a particular country on top of its territory and territorial waters or, more generally, any specific three-dimensional portion of the atmosphere.

Airspace is divided into two basic types:

• Controlled airspace exists where it is deemend necessary that Air traffic control has some form of positive executive control over aircraft flying in that airspace.

• Uncontrolled airspace is airspace in which air traffic control does not exert any executive authority, although it may act in an advisory manner.

Airspace may be further subdivided into a variety of areas and zones, including zones where there are either restrictions on flying activities or complete prohibition of flying activities.
