Exercise 12 - Stalls

Question 1

Stall Theory - Wing Drop

Answer 1

• Stall occurs simultaneously on both wings in coordinated flight, wings remain level throughout stall
• In uncoordinated flight, the inside wing stalls first creating wing drop
• More yaw = bigger wing drop
• Use rudder to correct
• MUST KEEP AILERONS NEUTRAL

Question 2

Stall Theory - Symptoms of the Approaching Stall

Answer 2

• Nose up
• Low Airspeed
• Loss of altitude
• Stall warning
• Control buffeting
• Back pressure

Question 3

Stall Theory - Key Points

Answer 3

• Published stall speed is for 1G
• Increasing load factor increases stall speed
• Avoid stalls by pushing the nose down
• Correct wing drop with opposite rudder

Question 4

Stall Prevention Procedure

Answer 4

• Nose down
• Apply power
• Return to desired condition

Question 5

Stall Entry Procedure

Answer 5

• HASEL check
• Set Power to desired setting
• Pitch up to maintain altitude
• Set flaps
• Identify approaching stall
• ## Increase back pressure just prior to stall

Question 6

Stall Recovery Procedure

Answer 6

• Reduce AOA
• Full Power
• Arrest and Correct Wing Drop
• Flaps up in Stages
• Regain altitude
• Return to Cruise

Question 7

Factors Affecting Stalls - Load Factor

Answer 7

• Load factor increases when AOA increases, stall speed increases

Question 8

Factors Affecting Stalls - Power

Answer 8

• Can reduce stall speed and affect yaw greatly

Question 9

Factors Affecting Stalls - Flaps

Answer 9

• Reduce stall speed
• ## Everything happens at a more nose-down attitude

Question 10

Factors Affecting Stalls - Weight and Balance

Answer 10

• Heavy aircraft have higher stall speeds
• Forward C of G produces higher stall speed
