What should number 2 do after ensuring separation when in a turn into number 2?

In formation flying, particularly in the T-6 context, maintaining proper separation and understanding your formation position is crucial for safety and coordination. After number 2 ensures that there is adequate separation during a turn, the best course of action is to resume the original turn. This allows number 2 to effectively re-establish their position within the formation while minimizing the risk of losing sight or compromising the formation's integrity.

Resuming the original turn ensures that number 2 can return to the desired flight path and maintain formation with number 1, which is essential for the overall safety and efficiency of the maneuver. It also helps to keep the flight cohesive, allowing all aircraft in the formation to stay synchronized.

Other options, like beginning a descent or notifying ATC of separation, could disrupt the formation's established flight path and cohesion, which is why they are not the preferred actions in this scenario. The call for rejoin could also imply a need for additional maneuvers or separation, which is unnecessary if number 2 is already capable of safely resuming their place in the formation after ensuring separation.
