� Types of drag:– Parasite drag
� Form drag: air going over aircraft parts like the antenna, engine covers, etc. having to split and rejoin
� Interference drag: air meeting at perpendicular joints of the aircraft flows over each in different currents/waves
� Skin friction drag: molecules sticking to the aircraft parts
– Induced drag� Low and high pressure air meeting and heading toward
the wing’s upper surface
