aircraft conflict

aircraft conflict

When an aircraft's position places it in a risk situation with another aircraft or airspace. It is predicted conflict within URET CCLD (user request evaluation tool core capability limited deployment), an automated tool provided at each radar associate position in selected en route facilities. The tool utilizes flight and radar data to determine present and future trajectories for all active and proposed aircraft, and it provides enhanced, automated flight data management of two aircraft, or between an aircraft and airspace. A red alert is sounded if the predicted minimum separation between two aircraft is 5 NM or less. A yellow alert means the predicted minimum separation is more than 5 up to and including 12 NM. A blue alert means a conflict situation exists between the aircraft and predefined airspace.

An aircraft alert/mode C is issued to a pilot if the controller observes another aircraft that places the two in an unsafe proximity. When feasible, the controller will offer the pilot an alternative course of action.

In this paper, these are referred to as STREAM algorithms (i.e., strategic trajectory deconfliction to enable seamless aircraft conflict management), which are consistent with the SESAR ATM target concept of operations; that is, they aim at proposing a set of deconflicted trajectories that respect the active ATM network constraints as well as the airspace users (AU) preferences in a free-route environment that covers the entire European Civil Aviation Conference (ECAC) airspace [7].

This system reduces the potential for runway incursions and aircraft conflicts; it also identifies more efficient, direct and co-ordinated paths to and from runways and gates, and reduces taxi times.
