  1. What force opposes and controls the adverse pressure gradient?
    The kinetic energy of the relative wind
  2. What is the definition of boundary layer separation?
    Point in streamline where airflow no longer adheres to the airfoil
  3. Which flight control would you expect to be most effective during a stall/stall recovery?
    Rudder
  4. How do you think increased G loading will affect stall airspeed?
    Stall airspeed increases
  5. If the aircraft is in a stall, what could happen if you misapply the controls or if the aircraft is out of trim?
    Aircraft could enter a spin
  6. During a spin, what will happen if the ailerons are deflected in spin direction?
    Roll and yaw will become more oscillatory
  7. Lower pitch attitude at stall results in higher stall airspeed (greater energy) which results in a ____ spin entry airspeed and____ oscillations.
    faster; greater
  8. What are the two main hazards associated with wake turbulence?
    Induced roll and induced flow field
  9. Power-off stall characteristics:
    • Power - idle
    • Stall airspeed - higher
    • Stall warning - closer to stall
    • Roll tendency - right
    • Yaw characteristic - less oscillation
  10. Power-on stall characteristics:
    • Power - above idle
    • Stall airspeed - lower
    • Stall warning - Further from stall
    • Roll tendency - left
    • Yaw characteristic - more oscillation
  11. What is the order of lost controls in a stall?
    • Ailerons
    • Elevator
    • Rudder
  12. Aerodynamic stall warning airspeed.
    • Power-off - 3 knots above stall speed
    • Power-on - slightly more than 3 knots above stall speed
  13. TAD operations during a stall
    Large system demands, rudder pedal feedback, helps directional stability, slows adverse yaw
  14. 2 key differences between power on & off stalls.
    • Vertical component of thrust increases lift & decreases stall speed
    • Prop acceleration factor increases flow over wings & decreases stall speed
  15. Boundary layer in T6 starts to separate when?
    15 units AOA
  16. T-6 windshear recovery procedures:
    • PCL MAX
    • 15 degrees nose up (minimum)
    • Do not allow <110KIAS or >10.5 AOA
    • If you're going to crash, consider ejecting
    • Once climb established, raise flaps & gear
    • Don't rely solely on VSI for climb info
    • Once in positive climb, reduce pitch in anticipation of exiting downdraft
  17. T6 windshear procedures on landing
    • Use Flaps takeoff
    • Increase approach speed by predicted shear (up to 10)
    • Establish approach pitch, trim and power by 1000 AGL
    • Accept higher airspeeds, use pitch & trim for glidepath
  18. T6 winshear procedures on takeoff
    • Use a long runway with few obstacles
    • Use TO flaps but delay rotation by amount of shear (up to 10)
    • Rotate to normal climb attitude at VROT+10 and hold that attitude
    • If windshear encountered near VROT, abort if possible
  19. Windshear PIREP should include what?
    Location, magnitude, description of what happened
  20. What can happen if a pilot is slow to recognize an increasing performance windshear on approach?
    A steep, fast approach can quickly develop
  21. Encountering a decreasing performance windshear on landing can have what effects?
    Cause the aircraft to pitch down & descend below glidepath
  22. Failing to recognize decreasing performance windshear can have what effects?
    Cause the aircraft to impact short of the runway
