At what airspeed will number 1 reduce power to 85-95% during an interval takeoff?

During an interval takeoff in the T-6, the lead aircraft, or number 1, will typically reduce power to 85-95% at a specific airspeed to ensure coordinated flight and provide a safe environment for the wingman to follow without excessive speed or risk of overtaking. The appropriate airspeed for this power reduction is 160 KIAS.

At this speed, the aircraft is in a position that allows for effective control while also maintaining sufficient energy for the maneuver. It is crucial for the lead to manage their airspeed to ensure that the wingman can safely maintain formation and prepare for their own takeoff, which follows shortly after the lead aircraft initiates its climb. Reducing power at this airspeed strikes a balance between adequate climb performance and safety margins, ensuring that both aircraft can operate effectively in the interval.

Choosing a lower or higher airspeed for power reduction could lead to complications, such as insufficient acceleration or an increased risk of the wingman catching up too quickly, which could compromise the formation integrity.
