What refers to the specific distance number 2 maintains behind lead during specific formations?

The term that refers to the specific distance that number 2 maintains behind the lead during specific formations is known as line spacing. In formation flying, maintaining the correct line spacing is crucial for effective communication, safety, and situational awareness among flight members. It ensures that the aircraft remain in the designated positions relative to each other, allowing for smoother maneuvers and enhanced team cohesion.

Effective line spacing depends on various factors, including aircraft type, speed, and environmental conditions, and is an essential aspect of formation flying training. Understanding and executing line spacing helps pilots maintain formation integrity and enhances overall flight performance during operations.
