What type of pursuit requires pointing the aircraft nose in front of number 1's flight path?

Lead pursuit is the technique where the pilot points the aircraft's nose in front of the lead aircraft's flight path. This approach is typically used during formation flying when adjustments need to be made for spacing and relative position, allowing for the desired intercept angle. By aiming ahead of the lead aircraft, the pursuing aircraft can account for the relative motion and anticipate where the lead will be in the future, thereby improving coordination and maintaining formation.

In contrast, lag pursuit focuses on flying behind the lead aircraft, which may be useful for maintaining distance but does not aid in intercepting or closing the gap effectively. Pure pursuit would involve directly aligning with the lead aircraft's current position rather than aiming forward, and cross pursuit involves maneuvers that include lateral movements. Thus, lead pursuit is specifically designed for scenarios requiring forward positioning, making it the correct answer for this question.
