What is a requirement for number 2 to not be further back than during lead change?

In a formation flying context, particularly during lead changes, maintaining appropriate position and spacing is crucial for safety and effectiveness. The requirement that number 2 must not be further back than 30 degrees during a lead change ensures that they remain within a safe and effective range relative to the lead aircraft. This range allows number 2 to have a clear line of sight and adequate visual references to maintain formation integrity.

Keeping the number 2 aircraft within this limit helps in reducing the potential for a separation issue that could arise if they were to fall too far behind. If number 2 were to exceed this angle, it could lead to complications in visual references, communication, and during subsequent maneuvers. The 30-degree limit promotes teamwork and coordination, essential components in formation flying. Therefore, this requirement is established to enhance safety and maintain close formation discipline during lead changes.
