Wing Loading (W/S)

Wing Loading (W/S) vs Aircraft Weight (W)
Formula
Wing Loading
Wing loading is the ratio of aircraft weight to wing planform area. It is one of the most fundamental parameters in aircraft design, directly influencing stall speed, climb rate, and maneuverability.
Formula
W/S = Weight / Wing Area
High wing loading means faster stall speeds and higher approach speeds but better ride quality in turbulence. Low wing loading enables slower flight and tighter turns but suffers more from gusts.
Esempio Risolto
A regional jet weighing 200 kN with a wing area of 80 m².
- 01W/S = 200000 N / 80 m²
- 02W/S = 2500 N/m²
- 03In kg/m²: 2500 / 9.81 = 254.8 kg/m²
Domande Frequenti
What are typical wing loading values?
Gliders have wing loading around 30-50 kg/m², light aircraft around 50-100 kg/m², airliners around 400-700 kg/m², and fighters around 300-500 kg/m².
How does wing loading affect stall speed?
Stall speed is proportional to the square root of wing loading: Vs = sqrt(2 W/(S rho CLmax)). Higher wing loading means higher stall and landing speeds.
Can wing loading change during flight?
Yes. As fuel burns off, the aircraft gets lighter and wing loading decreases. This is why aircraft burn less fuel per hour later in a long flight and can fly higher.
