In a turning rejoin, number 2 should position themselves how far below lead?

In a turning rejoin, number 2 should position themselves 2-4 ship widths below lead to ensure both safety and efficiency during the maneuver. This distance allows for sufficient vertical spacing to avoid potential collisions while maintaining enough proximity to maintain visual contact with the lead aircraft.

Positioning too closely could lead to an increased risk of misjudgment in altitude, particularly as both aircraft are maneuvering, while being too far away might compromise the formation integrity. The recommended distance of 2-4 ship widths provides a manageable space to account for any changes in speed or attitude of the lead aircraft during the turn, allowing number 2 to adjust smoothly and seamlessly join the formation.
