The four aerodynamics forces. - correct answer Thrust, Drag, Weight and Lift Thrust - correct answer The forward force produced by the power plant/propeller or rotor. It opposes or overcomes the force of drag. As a general rule, it acts parallel to the longitudinal axis. Drag - correct answer A rearward, retarding force caused by disruption of airflow by the wing rotor, fuselage, and other protruding objects. Drag opposes thrust and acts rearward parallel to the relative wind. Weight - ...
