When the weight of an aircraft increases the minimum drag speed?

When the weight of an aircraft increases, the minimum drag speed, also known as the stall speed, typically increases as well. This is because a heavier aircraft requires a higher angle of attack to generate enough lift to maintain flight, leading to increased induced drag. As a result, the speed at which the aircraft experiences the least drag, while still maintaining lift, also rises. Therefore, with greater weight, pilots must fly at higher speeds to achieve optimal performance and safety.
