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

The type of pursuit that requires pointing the aircraft nose directly at number 1's flight path is known as pure pursuit. In a pure pursuit scenario, the pilot aims the aircraft directly at the moving target, which, in this case, is the flight path of number 1. This method is often employed when the aim is to maintain a precise alignment with the target's trajectory, allowing for optimal control and positioning of the aircraft relative to the lead aircraft. It is particularly useful in dynamic flight situations where maintaining a direct line of sight is crucial for effective coordination and formation flying.

Other types of pursuit, such as lag and lead pursuits, involve aiming the aircraft in a different manner relative to the target. Lag pursuit means trailing behind the target, while lead pursuit involves aiming ahead of the target's path to intercept it. Cross pursuit is also a different tactical approach, and it would not involve pointing directly at the target's flight path. Therefore, in contexts where direct alignment with the flight path is necessary, pure pursuit is the correct approach.
