What is the recommended action if number 2 cannot maintain visual contact with number 1?

When number 2 cannot maintain visual contact with number 1 during formation flying, breaking off and rejoining later is the recommended action. Maintaining visual contact is crucial for safety and effective communication between aircraft in formation. If number 2 loses sight of number 1, it creates a risk of collision and hinders the formation's ability to maneuver together effectively.

Breaking off allows number 2 to regain visual contact without compromising the safety of the formation. Once visual contact is reestablished, number 2 can safely rejoin the formation. This approach prioritizes maintaining safe separation and situational awareness, ensuring that both aircraft can continue to operate effectively without risking unsafe maneuvers.

Adjusting altitude might seem like a logical step to regain visual contact, but without clear sight of number 1, this could lead to further complications and still not guarantee improved visibility. Initiating a lead change may also not address the immediate issue of lost visual contact. Therefore, breaking off and rejoining later is the most prudent action in this scenario.
