2. Aerodynamics 2 Aerodynamic Terms Angle of Attack Angle Between Chord Line & Relative Wind Relative Wind The direction of the airstream in relation to the airfoil

4. 4 Lift Is the force that acts in an upward direction to support the aircraft in the air. It counteracts the effects of weight. Lift must be greater than or equal to weight if flight is to be sustained. Lift acts perpendicular to relative wind Weight The force of gravity acting downward on the aircraft and everything in the aircraft, such as fuel and cargo. Aerodynamic Terms
