What defines "opposite courses" in air traffic control?

In air traffic control, "opposite courses" are defined by an angular difference of greater than 135° through 180°. This definition is crucial for the safe and effective management of aircraft movements and separation standards. When two aircraft are flying in nearly opposite directions, maintaining a separation that considers this angular difference is vital to avoid potential conflicts. When the angular difference is within this range, that means the aircraft pose a reduced risk of collision compared to those with a smaller angular difference, as they are effectively moving away from each other. This understanding helps air traffic controllers in making informed decisions about aircraft spacing and route adjustments, ensuring safety in busy airspace. The other options describe angular differences that do not meet the criteria for being classified as "opposite courses." The thresholds outlined in those options could allow for potential conflicts, hence they do not apply to the definition of opposite courses.
