Title: Describe the concept of angle of attack and airfoil stall.
Course: Aerospace Technology I (21055-I) > Section: Applying Aerodynamics

Description should include

- the definition of stall and spin
- the way that angle of attack may be increased to a point where lift is no longer created and stall occurs
- the effect of angle of attack
- stall recovery.

Process/Skill Questions:

- Why were spins used in early aircraft?
- What are the indications of a stall, spin, aggravated stall, approach turn stall, skidded turn stall?
- What thrust-to-weight ratio must an aircraft achieve to avoid stall?
- How does a pilot recover from a stall?
- What happens when an airfoil exceeds the critical angle of attack?
- What are the most common situations in which aircraft stall?
- How does the use of flaps affect stall speed? Why is this important in take-off and landing?
