Parasitic drag

Parasitic drag is a type of air resistance that acts against an aircraft's motion as it moves through the air. It includes all the forces caused by the aircraft's shape and surface that create resistance—such as the friction of air moving over the fuselage and the effects of protruding parts like antennas or landing gear. Essentially, parasitic drag increases with speed and requires more engine power to overcome, impacting fuel efficiency and speed. It can be minimized through streamlined design and proper maintenance, helping the aircraft fly more smoothly and efficiently.
