  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The last point on an airfoil that interacts with the airflow around the wing.

2. A sequence of drawings representing the shots planned for a film or television production.

3. A short - memorable phrase used in advertising or associated with a political party or group.

4. An aircraft that is designed to fly without an engine.

5. A straight line through the center of gravity of the aircraft and at 90

6. The movement about the vertical axis produced by the rudder and controlled by pedals.

7. The flat surfaces located behind the center of gravity tend to weathervane with the wind.

8. The rate at which temperature decreases with an increase in altitude.

9. The distance from wing tip to wing tip of a wing planform.

10. Out of its own accord - an aircraft eventually returns to and remains at its equilibrium position over a period of time.

11. The common reference point for the three axes of the aircraft.

12. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.

13. Aircraft speeds between Mach 10 and 25.

14. Consists of both the engine and propeller in a small airplane.

15. Design machines that fly.

16. Aircraft speeds under Mach 1.

17. Mach. A decimal number representing the true airspeed relationship to the local speed of sound.

18. Forces and moments on the body caused by a disturbance tend initially to return the body toward its equilibrium position.

19. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.

20. The tail assembly of an aircraft - including the horizontal and vertical stabilizers - elevators and rudder.

21. Generates the lifting force that helps the airplane fly when air flows around it.

22. Hinged main surface part that help control banking for a turn

23. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.

24. A force caused by the gravitational attraction of the Earth.

25. A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.

26. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.

27. Caused by the separation of airflow from the wing's upper surface resulting in a rapid decrease in lift.

28. Robotic aircraft - used extensively by the military.

29. Rolling motion about the longitudinal axis caused by ailerons deflecting in opposite directions and controlled by twisting the yoke.

30. The mounting of wings so that the wingtips and higher than the wingroot.

31. The horizontal line that passes through the center of gravity of the aircraft - perpendicular to its flight path.

32. The art and science of designing - building - and operating manned or unmanned space objects

33. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.

34. Aircraft speeds between Mach 1 and 5.

35. A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.

36. An aircraft with floats or skis instead of wheels - designed to land on and take off from water.

37. Branch of technology and industry concerned with aviation and space flight.

38. The angle formed by the wing chord line and the relative wind.

39. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.

40. Aircraft speeds between Mach 5 and 10.

41. Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.

42. The study of forces and the resulting motion of objects through the air.

43. A short - easily- remembered slogan - verse - or tune.

44. Aircraft stability is the characteristic of an airplane in flight that causes it to return to a condition of equilibrium - or steady flight - after it is disturbed.

45. The outline shape of a wing when viewed from above.

46. A rear vertical stabilizer that controls side- to- side or yawing motion of the aircraft nose.

47. A powered heavier- than - air aircraft with fixed wings from which the aircraft derives most of its lift.

48. Forward- acting force which opposes drag and propels the aircraft through the air.

49. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.

50. A glider designed for sustained flight.
