In air traffic control, what does an angular difference greater than 135° indicate?

An angular difference greater than 135° typically indicates that aircraft are on opposite courses. When two aircraft are heading in directions that are more than 135° apart from each other, they are effectively moving away from one another in a way that diminishes the likelihood of convergence towards a common point. This separation can be an important factor for safety in air traffic control, as it assists controllers in maintaining safe distances between aircraft. While aircraft on the same course would have an angular difference of 0°, and those on crossing courses would typically be in the range of 30° to 150°, understanding that a difference greater than 135° represents opposite courses helps emphasize the operational aspects of navigation and separation techniques used in ATC. This understanding is critical for controllers when making decisions about air traffic flow and ensuring the safety of flight operations.
