What is the minimum airspeed number 1 must achieve before raising gear and flaps on a wing takeoff?

The minimum airspeed that number 1 must achieve before raising the gear and flaps during a wing takeoff is 110 KIAS. This speed is crucial for ensuring a stable and controlled transition during takeoff, especially in a formation flight scenario where maintaining precise control is vital. At 110 KIAS, the aircraft has sufficient lift and control authority, which is essential to safely raise the landing gear and flaps without risking a loss of performance or stability.

Raising the gear and flaps prematurely may lead to increased drag and a potential loss of lift, which is particularly concerning when the aircraft is at a relatively low altitude and airspeed. Adhering to this specific speed ensures that the aircraft is operating within a safe envelope, minimizing the risks associated with a premature configuration change while ensuring that the formation remains intact and stable.
