Closest Point of Approach (CPA) refers to the estimated closest distance between two moving objects, such as ships, aircraft, or vehicles, particularly in scenarios where collision avoidance is critical. It is calculated by predicting the future positions of the vessels based on their current courses and speeds.
CPA is used to predict when and where the moving objects will come closest to each other, allowing for proactive measures to be taken to ensure safe separation and prevent collisions. It is most commonly used in the context of maritime navigation and air traffic control.
CPA helps the operator assess the risk of collision and take appropriate action to avoid it, such as altering course or speed.
The full form of CPA is Closest Point of Approach
