Explain the factors affecting air pressure around an airfoil.

Explanation should include how the following factors affect an airfoil in flight: 

• Temperature affects the lift generated by the airfoil. 
• Air speed increases the pressure difference between the upper and lower wing surfaces. 
• Altitude decreases the airfoil efficiency. 
• Angle of attack affects the airflow over the wing.
• Air density is affected by all of the above and the implications on flight dynamics.  

Process/Skill Questions: 

• What are the effects of temperature on an airfoil? 
• What are the effects of airspeed over a wing?
