Airspace
*** Shopping-Tip: Airspace
'''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 portion of the atmosphere.
Aviators divide airspace into three basic types:
*
Uncontrolled airspace is airspace in which
air traffic control does not exert any authority. It exists close to the ground or in mountainous terrain where safe flight under
instrument flight rules (IFR) and radar coverage are impossible.
*
Controlled airspace exists almost every place else.
Air traffic control is capable of directing aircraft in this airspace (though does not necessarily do so).
* Special use airspace (SUA) refers to areas where flight is prohibited, restricted, or otherwise limited. In the U.S., SUAs are designated for reasons of national security, including routine military use. Areas are determined by the owning agency (Military or CAA(UK)/FAA(US)). One example of Prohibited airspace is the Mall area in
Washington, D.C. which contains the
White House and the
US Capitol. Another example is that over Royal Palaces and
Whitehall (Government buildings and
10 Downing Street) in the UK. Some SUAs, such as those associated with military exercises, are active only part-time, and others are full-time. SUAs are usually in controlled airpace. ''Temporary Flight Restrictions'', imposed for reasons such as environmental emergency management or VIP protection, are not defined as SUAs.
