wing_area | Wing Area (S)(m²) | 80 |
How It Works
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.
Worked Example
A regional jet weighing 200 kN with a wing area of 80 m².
weight = 200000wing_area = 80
- 01W/S = 200000 N / 80 m²
- 02W/S = 2500 N/m²
- 03In kg/m²: 2500 / 9.81 = 254.8 kg/m²
