Stalling speed calculator

stalling speed (Vs) refers to the minimum speed at which an aircraft can maintain level flight without stalling. Stalling occurs when the critical angle of attack is exceeded, and the airflow over the wings becomes separated, leading to a loss of lift and a significant decrease in the aircraft’s performance.

• Vs​ is the speed of the object.
• $s$ is the span (distance) of the object.
• $W$ is the weight of the object.
• $\rho$ is the air density.
• $S$ is the surface area of the lifting surface (e.g., wings).
• $C$ is the lift coefficient.
• Lmax​ is the maximum lift of the object.
