How should number 2 communicate in the situation of a turn into number 2 during Lost Wingman procedures?

In the situation of a turn into number 2 during Lost Wingman procedures, the correct course of action is for number 2 to direct to roll out and state they are the lost wingman. This communication is critical as it clearly conveys to both their wingman and any outside observers or air traffic control that they have lost visual and situational awareness of their flight lead.

By directing to roll out, number 2 can stabilize their flight path, which is essential for maintaining safety and avoiding potential collisions. Stating they are the lost wingman ensures all parties involved are aware of the situation, thereby preventing misunderstandings and allowing for coordinated actions to be taken. This communication method adheres to established procedures that emphasize clarity and safety during a potentially stressful scenario.

Options such as calling for immediate landing or requesting assistance from ATC, while potentially useful in different contexts, do not address the immediate need to stabilize the formation and reconnect with the flight lead. Notifying ground control is not relevant here, as the situation pertains to airborne operations and safety during flight, rather than ground activities. Thus, the most appropriate and effective response in this specific situation revolves around the actions outlined in the correct answer.
