Stall Speed Calculator

Stall Speed Calculator

The Stall Speed Calculator is a tool used in aviation to estimate the minimum airspeed at which an aircraft can maintain level flight before stalling. Stall speed is an important parameter in flight performance and safety considerations.

It helps pilots determine the safe operating limits of an aircraft during takeoff, landing, and maneuvers.


The formula for calculating stall speed varies depending on the specific aircraft and its configuration, including factors such as weight, wing area, and wing loading. However, a simplified formula commonly used is:

Stall Speed = √((2 * Weight) / (Air Density * Wing Area * Lift Coefficient))


If an aircraft weighs 2500 pounds, the air density is 0.0023 slugs/ft^3, the wing area is 200 square feet, and the lift coefficient is 1.2, the stall speed can be calculated as follows:

Stall Speed = √((2 * 2500) / (0.0023 * 200 * 1.2)) ≈ 58.39 ft/s
