  1. Arm
    Distance from the Reference Datum Line
  2. Moment
    Weight x Arm usually divided by 1000
  3. CG
    Total Moment divided by Total Weight
  4. Four Forces of Flight
    • Thrust
    • Drag
    • Weight
    • Lift
  5. Angle of Attack
    Angle that the wing goes through the RELATIVE wind
  6. Chord Line
    Line straight through wing from leading to trailing edge
  7. Two Types of Drag
    • Parasite
    • Induced
  8. Types of Parasite Drag
    • Form
    • Interference
    • Skin Friction
  9. Left Turning Tendencies (4)
    • Torque Effect
    • Gyroscopic Precession
    • Spiraling Slipstream
    • P-Factor
  10. What enables an airplane to climb?
    Excess Thrust
  11. Center of Pressure
    Center of Lift - aft of CG
  12. Dihedral
    Upward Angle of Airplanes Wings
  13. Keel Effect
    Side of fuselage and vertical stabalizer creating lateral stability
  14. Induced Drag
    Increases as Airspeed Decreases
  15. Parasite Drag
    Increases with Airspeed
  16. Positive Static Stability
    Initial Tendency to be stable
  17. Positive Dynamic Stability
    Tendency to return to stable condition over time
  18. Angle of Incedence
    Angle that the wing is mounted to the fuselage
  19. Wing Twist
    Wing is twisted so outer wing stalls later
  20. Flap Types (4)
    • Plain - increases lift/drag - changes wing
    • Split - increases lift/drag - changes bottom wing
    • Slotted - increases lift/drag - increases wing area - airflow
    • Fowler - increases lift/drag - increases wing area
  21. Camber
    Curve of airfoils - upper/lower surfaces
  22. Aspect Ratio
    Relationship between length & width of wing
  23. Planform
    Shape of wing
  24. Bernoullis Principle
    • As velocity increases, pressure decreases
    • Velocity on upper surface is greater than lower
  25. Stall due to:
    EXCEEDING THE CRITICAL ANGLE OF ATTACK
  26. Load Factor
    Ratio of load supported by wings to the actual amount supported

    Total Load Supported divided by Total Weight

    G FORCES
