### How much lift will a wing generate?

A wing will generate lift according to the following
equation:
L = ½ A C ρ v²
A = wing area
C = lift coefficient
ρ = air density
v = air speed
The lift coefficient C is a function of Angle of Attack (AOA),
which is the angle between the wing's chord line and the relative
wind. The greater the angle, the greater the lift coefficient up
until the critical AOA where the wing begins to stall and lose
lift. The lift coefficient is also a function of wing aspect ratio
and will be specific to a certain airfoil shape.

### What is the point at which lift starts to drop off?

This is termed the Critical Angle of Attack and represents a
maximum in the Lift Coefficient vs. Angle of Attack curve. If the
angle of attack is increased beyond this point, the wing will
stall. For most airfoils, the critical angle of attack is around 15
deg. For swept back wings it is typically higher.

### How is the lift equation useful when you are designing a wing?

A wing will generate lift according to the following
equation:
L = ½ A C ρ v²
A = wing area
C = lift coefficient
ρ = air density
v = air speed
From the equation you can see that the lift force is directly
proportional to the wing area. Double the wing area and you double
the lift, all else remaining equal. The lift force is also directly
proportional to the lift coefficient, which is a function of the
airfoil shape, angle of attack and wing aspect ratio. Lift is
directly proportional the air density, so this tells you that an
airplane flying at sea level can produce more lift than if flying
at 18,000 feet. Lift is proportional to the square of velocity,
meaning that if you fly twice as fast you will generate 4 times the
lift, all else being equal.

### Why do large wings have more lift?

A wing will generate lift according to the following
equation:
L = ½ A C ρ v²
A = wing area
C = lift coefficient
ρ = air density
v = air speed
From the equation you can see that the lift force is directly
proportional to the wing area. Double the wing area and you double
the lift, all else remaining equal.
