- The mean aerodynamic chord (MAC) of a wing is a quantity used to represent the average chord length of the wing.
- It is defined as the area of the wing divided by the wingspan.
- The MAC is a useful parameter because it can be used to calculate the lift and drag forces acting on a wing.
- It is also used in the design of aircraft wings.
- The MAC of a wing is typically measured in meters (m) or feet (ft).
