Parasite drag is made up of all the forms of drag that act on any object that moves through a fluid. It is made up of:

• skin friction drag
• form drag
• interference drag.

Parasite drag is that which is produced even when lift is not produced, and induced drag is that which is caused when the airplane’s airfoils are producing lift.

Induced drag, on the other hand, is the section of lift that acts parallel to the relative airflow, due to the limited length of the wing, and the effect of three-dimensional aerodynamics.
