Induced drag for steady level flight is a type of drag that arises due to the generation of lift by an aircraft’s wings. When an aircraft is flying in steady level flight, it is producing lift to counteract its weight and maintain a constant altitude. This lift is generated by creating a pressure difference between

Induced drag force, often simply referred to as “induced drag,” is a type of drag that arises due to the generation of lift by an aircraft’s wings. When an aircraft is producing lift, it creates pressure differences between the upper and lower surfaces of the wings. This pressure difference leads to the creation of vortices

The lift curve slope for a finite wing, often denoted as “a,” is an aerodynamic parameter that quantifies the rate of change of lift coefficient (“CL”) with respect to changes in the angle of attack (“α”) for an aircraft wing with finite span. In other words, it represents how much additional lift is generated for
