eng.wing-loading-stall-speed Calculator
Calculates wing stall speed from wing area, aircraft weight, and maximum lift coefficient, and the relationship to wing loading. Stall speed scales with √(W/S) — doubling wing loading increases stall speed by √2 = 41%, driving the tradeoff between wing area and takeoff/landing performance.
Inputs
W N
Body or object weight. For health calculators, usually in kg or lbs.
S M2
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Clmax
Reference formula or conversion factor shown for context.
Rho Kg M3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Results
stall speed Vs (m/s)
The computed rate of movement or processing.
stall speed Vs (knots)
The computed rate of movement or processing.
wing loading W/S (N/m²)
Sample size or count used in the calculation.
Vs = √(2W/(ρ·S·CLmax))
