Across
- 2. Smaller and lighter than longerons, these rigid components serve to fill in as stiffeners when riveted to fuselage and wing skin
- 5. Angle that the wing's imaginary line makes with the longitudinal axis of the aircraft
- 7. Airfoil sections may be tapered, twisted, or _____
- 8. Number of stresses an aircraft may succomb to
- 9. Controlled by elevator, providing longitudinal stability
- 12. The three axes of rotation act through this concentrated point (abreviated)
- 14. Imaginary straight line that passes through wing or airfoil from leading edge to trailing edge
- 17. What happens to lift as the AOA increases
- 18. Cause of some unsafe airport & shop environments and aviation catastrophes, like the Concorde Crash
- 19. If the control stick of an aircraft with properly rigged flight controls is moved to the left, the right aileron will move
- 21. Structural partitions placed throughout the fuselage and wings, separating aircraft and wing sections
- 23. If the control stick of an aircraft with properly rigged flight controls is moved rearward, the elevator will move
- 24. Angle formed by chord line and a line indicating direction of the relative airstream
- 26. Aerodynamic part of airfoil that determines the amount of turbulence or skin friction produced
- 29. An aircraft must have sufficient ____ to maintain a uniform flightpath and recover from the various upsetting forces
- 31. Structural partitions placed to prevent fire from crossing into the cabin
- 32. Ratio comparing wingspan to chord line, perhaps as a measurement of obtaining greater lift
- 34. Provides primary fuselage and wing structure, running longitudinally
- 35. Controlled by airlerons, providing lateral stability
Down
- 1. Term for a wing, or any aerodynamic surface that creates lift
- 3. A part of a wing's measurement of area, taken from wing root to tip
- 4. Its structure types include monocoque, semi-monocoque, and truss

- 10. Shape of an airfoil or cambered surface
- 11. Flight control surfaces that helpt to streamline stability of movement of the aircraft
- 13. Part of airplane that provides lift
- 15. Pressure needed below the wing for lift to occur, as opposed to the pressure above the wing
- 16. Stress that resists squeezing force
- 20. Structural crosspieces that give the wing its cambered shape
- 22. Stress that resists tearing force
- 25. Stress that resists "pulling apart" force
- 27. Controlled by rudder, providing directional stability
- 28. Movement from leading edge to trailing edge, nose to tail, etc.
- 30. Stress that resists twisting force
- 33. Part of airplane that provides thrust, which is not considered a part of the airframe
