How much overtake does number 2 use in a turning rejoin?

In a turning rejoin, number 2 uses 20-30 knots of overtake until they are within 500 feet of the lead aircraft. This overtake speed helps maintain a safe and effective approach while allowing number 2 to align properly with the lead for a smooth rejoin. At this distance, the extra speed compensates for any geometric changes in the formation and assists in minimizing the potential for excessive closure rates, which could result in safety issues or misalignment during the maneuver.

Once within this specified range, number 2 can manage their speed more effectively as they hone in on the formation and prepare to establish the appropriate fingertip position. Using the right speed for overtake is critical in ensuring that the aircraft can safely and efficiently transition into the desired formation configuration without risking a premature or unstable rejoin.
