What happens to AA and closure with lead pursuit?

In a lead pursuit scenario, the pilot positions their aircraft to achieve an angle that allows them to intercept the target sooner than if they were flying directly toward it. This results in an increase in both the aspect angle (AA) and closure rate to the target.

As the pilot maintains a lead pursuit, the aircraft's trajectory is aimed forward of the target's flight path. This configuration effectively reduces the time and distance to intercept the target, leading to a more pronounced increase in closure. Consequently, the increase in AA indicates that the angular separation between the two aircraft is widening in relation to their movement paths, resulting in a higher closure rate as the pursuing aircraft approaches the target more quickly. This tactical maneuver is particularly useful in formation flying and combat scenarios, where accurate positioning and timely engagement are critical.
