|Quoting A342 (Thread starter):|
How does ATC treat these aircraft in international airspace? Do they communicate with the crews and carry out all the standard procedures or what? Do these aircraft fly at large distances to civil aircraft?
This might help you understand the situation you're talking about. Remember there are two different issues here. First territorial boundaries and then airspace controlled by ICAO agreement.
The concept of "Due Regard" is recognized by ICAO.
The Department of Defense issued DOD Directive 4540.1, Use of Airspace by United States Military Aircraft and Firings Over the High Seas, for situations when DOD aircraft are not able to accomplish the mission while complying with ICAO procedures for point-to-point and navigation flights. There are operational situations that do not lend themselves to ICAO flight procedures. These situations may include politically sensitive missions, military contingencies or classified missions. When operations of this type are not conducted under ICAO flight procedures, they are conducted under the "due regard" prerogative of military aircraft. Due regard means that the aircraft commander, of a state aircraft, will operate that aircraft with "due regard" for the safety of all air and surface traffic. Before an aircraft commander can declare due regard, there are certain conditions that must be met:
(1) Aircraft shall be operated in VMC; or
(2) Aircraft shall be operated within radar surveillance and radio communications of a surface radar facility; or
(3) Aircraft shall be equipped with airborne radar that is sufficient to provide separation between themselves, aircraft they may be controlling, and other aircraft; or
(4) Aircraft shall be operated outside controlled airspace and, when possible, away from high density traffic areas
Hope this helps??
