relative wind
Also known as: apparent wind
Quick Summary
Relative wind refers to the motion of the air in relation to a body within it. In aviation, it's crucial for understanding how air interacts with an airfoil, such as a wing or rotor blade.12
For an airplane, the relative wind is determined by the aircraft's forward flight path. In a helicopter, it's more complex, influenced by the rotation of the rotor blades, the helicopter's movement, and even wind conditions. The angle of attack, the angle at which the relative wind meets the airfoil, is vital for generating lift.23
