Description

This article describes vectoring from a geometric point of view. It elaborates on:

• Conflict geometry, which determines the need for vectoring, i.e. the calculations performed to determine whether controller intervention would be necessary;
• Factors affecting the controller's choice of aircraft to be vectored;
• How the direction of the turn is determined; and,
• Impact of the track crossing angle on the situation in terms of separation gained by vectoring and separation lost after the crossing point.

Conflict Geometry

Crossing point is the point where the tracks of the two aircraft intersect.

Closest Point of Approach (CPA) is the point when the distance between the aircraft is at its minimum.
