Wing loading - Wikipedia, the free encyclopedia
Higher wing loading drastically reduces take-off and landing performance.
That' s why you use Fowler-type flaps during these phases on airliners with high wing loadings.
The fuel economy is not necessarily worse for aircraft with a higher wing loading.
Otherwise we would see A320' s with A380 wings.
The reasons for this are:
In the formula of drag, increased S can significantly increase the induced drag.
Or another problem is that an increased S can increase mass.
Increased S can also decrease CL, depending on how the additional surface is won.
It all comes down to the right wing loading for the right speed.
