AVIATION & AERONAUTIC CALCULATOR
Stall Speed Clean
A precise tool.
What is the Stall Speed Clean & How does it work?
Stall speed is the minimum airspeed at which an aircraft can maintain level flight without descending. It is a critical parameter for understanding the aerodynamic performance of an aircraft.
The stall speed in clean configuration (without flaps or other drag-producing devices) is primarily influenced by the wing’s lift coefficient, weight of the aircraft, and air density.
V_s = sqrt{frac{2W}{rho S C_L_{max}}}
V_s = Stall speed, W = Weight of the aircraft, rho = Air density, S = Wing area, C_L_{max} = Maximum lift coefficient

Frequently Asked Questions
What is stall speed in aviation?
Stall speed is the minimum airspeed at which an aircraft can maintain level flight without descending.
How does weight affect stall speed?
An increase in aircraft weight increases the stall speed, as more lift is required to counteract gravity.
What role does air density play in stall speed calculation?
Air density affects stall speed inversely; higher density requires less speed for the same amount of lift.
How do flaps affect stall speed?
Flaps increase wing area and lift coefficient, reducing stall speed but increasing drag.
What is the formula for calculating stall speed in clean configuration?
V_s = sqrt(2W / (rho * S * C_L_max)), where V_s is stall speed, W is weight, rho is air density, S is wing area, and C_L_max is the maximum lift coefficient.
Why is stall speed important for pilots?
Stall speed is crucial for pilots to understand aircraft performance limits and maintain safe flight operations.
Can stall speed vary with altitude?
Yes, stall speed can vary with altitude due to changes in air density; it generally increases with higher altitudes.
