Safety Considerations Safety Requirements : None Risk Assessment Level : Low Environmental Considerations : None
Aerodynamic Terms Angle of Attack Angle Between Chord Line & Relative Wind Relative Wind The direction of the airstream in relation to the airfoil
Angle of Attack
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.
