Which of the following applies during the cell formation setup with A/P and A/A TACAN?

In the context of cell formation setup using A/P (autopilot) and A/A TACAN (Tactical Air Navigation), the correct choice indicates that both the lead and wingman aircraft have their autopilot engaged. This is essential for maintaining a stable formation where both aircraft can synchronize their movements without manual control fluctuations. When both aircraft utilize autopilot, it minimizes pilot workload, reduces the risk of human error, and allows for precise positioning relative to one another, which is crucial during flight in formation.

Engaging autopilot in both aircraft ensures that they can maintain a consistent spacing and heading, facilitating a smoother and safer coordination, especially in operations that require close proximity such as during aerial refueling or tactical maneuvers. This setup allows the lead to set a specific flight path that the wingman can follow, enhancing overall efficiency and safety in the formation flying environment.
