Parasite drag is caused by the aircraft itself and its components being exposed to the relative airflow. We can break parasite drag down even further. (1 Form Drag is drag due to the shape of the aircraft1 $1 Interference Drag is created when different types of surfaces meet or join such as where the wing meets the aircraft fuselage1 1 Skin Friction Drag is due to the smoothness or roughness of the aircraft’s skin. Parasite drag Induced drag is drag caused by the lift being produced by the wing. Induced drag Drag acts rearward in the opposite direction of the aircraft and in the same direction as the relative airflow. The total drag force on the aircraft changes depending on weight, aircraft configuration, airspeed, temperature and pressure. Drag opposes thrust Total drag is a mixture of both induced and parasite drag. Induced drag reduces as speed increases and parasite drag increases as speed increases. Total drag versus airspeed In level flight there is a small relationship between attitude and angle attack. Most small training aircraft do not have an angle of attack indicator. In level flight at normal operating speeds the attitude is closely related to the angle of attack. Relationship between attitude and angle of attack Ch.2 - How an aircraft generates lift
