Across
  1. 2. the load factor at 60 degrees of bank
  2. 5. a fixed angle at which the wing is mounted to the aircraft
  3. 10. this type of propeller can be changed by the pilot, changing from a coarse pitch to a fine pitch
  4. 12. this type of drag is caused by the parts of an airplane that do NOT produce lift, and increases with speed
  5. 13. on the upper surface of a wing; they disrupt lift
  6. 16. this wing design enhances lateral stability
  7. 18. mounted on the leading edge of a wing, they provide the same effect as washout
  8. 21. this type of drag is caused by air clinging to the surface
  9. 22. stress imposed by turbulence
  10. 24. according to the lift formula, tripling the velocity will increase the resulting lift by this much
  11. 25. this type of pitch on a propeller is the theoretical distance a propeller should move forward in one rotation
  12. 26. relative curvature of a wing
  13. 27. if thrust is greater than drag, the airplane will do this
  14. 30. this type of wing tapers back towards the tail
  15. 31. stability around the longitudinal axis is also called ___ stability
  16. 32. these parts open forward of the main wing, to smooth out the airflow over the wing
Down
  1. 1. small vertical tabs on the upper surface of a wing, it delays boundary layer separation
  2. 3. this type of drag is caused by the parts of an airplane that produce lift, and increases when the angle of attack increases
  3. 4. distance from wingtip to wingtip
  4. 6. if lift is greater than weight, the airplane will do this
  5. 7. the type of flow that has improved boundary layer characteristics; the separation point of the boundary layer is further aft on the wing
  6. 8. the shape of a wing when viewed from above
  7. 9. the wing span divided by wing chord
  8. 11. this adverse yaw is caused by the corkscrew movement of the air around the airplane
  9. 14. this type of stability means the aircraft is stable due to design features
  10. 15. is the difference between how far a propeller should advance in one rotation, and how far it actually advances
  11. 17. the wing is twisted, improving stall characteristics
  12. 19. these are openings in the leading edge of wings, they allow air to pass through
  13. 20. small vertical fins on top of the wing to smooth airflow over the wing
  14. 23. an airplane that has an overall tendency to return to its original state of flight has ___ stability
  15. 28. the distance from the leading edge to the trailing edge
  16. 29. longitudinal stability is around the _____ axis
