  1. What increases AOA, and puts an aircraft very close to a stall?
    High pitch attitudes, high G loading, flying at slow airspeeds
  2. What senses and sensations does a pilot develop to help recognize impending stalls?
    • Visual indications
    • Auditory indications
    • Pilot kinesthesia
    • Control pressure feedback
  3. What is Kinesthesia?
    • "seat of the pants"
    • The sensing for change in direction or speed of motion
  4. What are the two indications of a developing stall?
    • Buffet caused by turbulent airflow striking the empennage causing rudder and elevator to shake; 3 knots above stall speed
    • Stick shaker - activates 5-10 knots above stall
  5. What are the two things that will occur during a stall?
    • For training purposes, full stall is considered the point at which the first:
    • Uncommanded nose drop
    • Uncommanded rolling motion
  6. Power-on stalls teach three important concepts:
    • Recognition of nose-high attitude full stalls
    • Practice minimum altitude loss stall recovery when engine power is available
    • Recognition of secondary stall, if entered, and proper recovery
  7. What are the three checks that must be accomplished prior to practicing stalls?
    • Complete the pre-stall checklist
    • Plan you entry to ensure you stay in your assigned area
    • Clear for possible conflicts - above, below, in front, in direction of turn
  8. Power-on stall setup/recovery:
    • Nose-low entry - 15-30° nose high, or
    • Nose-high entry - 30-40° nose high
    • If a turn is required, establish 20-30° bank
    • Set 30-60% torque
    • Recovery:
    • 1. Reduce AOA
    • 2. PCL MAX
    • 3. Level wings
    • 4. Raise pitch - (recovery 15.5-18 AOA) minimum altitude loss
    • Maneuver is complete when positive climb is established
  9. Why are traffic pattern stalls practiced?
    • Develop you recognition of potential stall situations that can occur in the traffic pattern
    • Develop your skills and confidence in recovering from developing low altitude stalls with minimum altitude loss
  10. What is the concept for traffic pattern stalls?
    • Emphasis is on recognizing the approach-to-stall, and using proper recovery procedures
    • Recovery begins when you first recognize an approach-to-stall situation - stick shaker
  11. How to set up a break stall and recovery:
    • Set up on a simulated initial and adjust power to maintain 200 knots
    • Retard the PCL to approximately 10% torque and roll into a 60° bank turn
    • Midway through the turn, increase bank and back stick pressure until an approach-to-stall indication is recognized
    • Recovery:
    • Decrease AOA
    • Adjust bank angle
    • Continue turn to downwind leg
  12. How to set up a overshooting (nose-low) final turn stall and recovery:
    • Aircraft configuration - 120 KIAS, flaps LDG
    • Initiate a normal final turn
    • Steadily increase bank, back pressure, PCL idle
    • Recognize an approach-to-stall
    • Recovery: Simultaneously
    • Recovery AOA (15.5-18 units)
    • PCL-MAX
    • Level wings
    • Minimize altitude loss
    • Establish positive climb
  13. How to set up for a undershooting (nose-high) final turn stall and recovery:
    • Aircraft landing configuration 120 knots
    • Begin normal final turn
    • Raise nose slightly, shallow out the bank, PCL-IDLE
    • Recognize approach-to-stall
    • Recovery: Simultaneously
    • Recovery AOA (15.5-18 units)
    • PCL - MAX
    • Level wings
    • Minimize altitude loss
    • Establish climb
  14. Landing attitude stall set up and recovery:
    • Final approach profile, 5-10 knots above final approach speed
    • PCL - IDLE
    • Hold landing attitude
    • Recognize approach-to-stall
    • Recovery:
    • Recovery AOA (15.5-18 units)
    • PCL - MAX
    • Maintain landing attitude and establish a climb
  15. Closed pull-up stall set up and recovery:
    • Establish 140 KIAS
    • Roll aircraft and pull to simulate an over-aggressive closed pattern
    • Recovery:
    • Reduce stick pressure
    • Rapidly rolling wings level
    • Power - 60%
  16. Clean glide to high key stall set up/recovery:
    • Clean glide at 125 KIAS
    • Torque 4-6%
    • Increase pitch slightly
    • Recovery: At gear horn (120 KIAS)
    • Lower pitch slightly, airspeed 125 KIAS
    • Should take approximately 300' of altitude
  17. High key to low key ELP stall set up/recovery:
    • Gear down
    • 30° bank turn
    • 120 KIAS
    • 4-6% torque
    • Increase pitch - level flight
    • Recover at approach-to-stall indication (stick shaker)
    • Recovery: 
    • Lower pitch 8° nose low, 120 KIAS
    • Should take approximately 800' of altitude
  18. Low key to runway ELP stall set up/recovery:
    • Gear, TO flaps extended, 120 KIAS, 4-6% torque
    • Increase pitch to level attitude
    • Recover at stick shaker or approach-to-stall indication
    • Recovery: lower pitch to 8° nose low, 120 KIAS
    • Should take approximately 900' of altitude
  19. Why is an intentional slip maneuver performed?
    you can significantly increase your descent rate but still maintain a constant airspeed and ground track
  20. Slow flight set up, landing configuration:
    • Pitch attitude 8° nose high
    • Airspeed - 80-85 KIAS for flaps LDG
    • Airspeed - 85-90 KIAS for flaps TO (15 AOA)
    • 45% torque
    • Trim
  21. Slow flight set up, clean configuration:
    • Pitch - 10° nose up
    • Airspeed - 90-95 KIAS
    • 40% torque
  22. During straight and level flight, the slower you go:
    • The higher the pitch you need to maintain altitude
    • The higher the power you need to maintain speed
    • The greater rudder deflection required to counter increased engine torque
  23. How do you accomplish the coordination exercise?
    • Conduct a series of 15-20° bank turns
    • Expect to use 4" of right rudder for a right turn; 1/2" right rudder for left turn
    • Smooth control movements
  24. If an aircraft is put in a shallow turn without rudder, what happens?
    the initial tendency is for the nose to track away from the direction of the turn due to adverse yaw
  25. If an aircraft is in straight and level flight and power is increased to max, what will happen?
    nose will track up, yaws, and rolls left causing airspeed to decrease and the aircraft to approach a stall.
  26. Abrupt control movement during slow flight illustrates what?
    • The small margin between slow flight and stall
    • Aircraft will quickly approach stall with little or no stall warning
  27. Flap retraction demonstration during straight and level flight:
    • Retract flaps
    • Notice initially that the airspeed increases slightly, then, AOA increases and quickly, the aircraft progresses towards a stall
  28. Control effectiveness demonstration:
    • Rapidly move all three control surfaces.
    • Rapid inputs have little to no effect on the aircraft
  29. During slow flight, quickly increasing power to MAX with no other control inputs will cause the nose to track ___ and ____, causing airspeed to decrease and the aircraft to approach a stall
    up; left
  30. During the slow flight coordination exercise, fly a series of left and right turns using____ of bank.
    15°-20°
