  • 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. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.

2. Acts in the opposite direction of flight - opposes the forward- acting force of thrust - and limits the forward speed of the aircraft.

3. An advertising film which promotes a product in an informative and supposedly objective style.

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

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

6. 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.

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

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

9. The last point on an airfoil that interacts with the airflow around the wing.

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

11. Robotic aircraft - used extensively by the military.

12. Characteristic of the aircraft that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuver.

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

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

15. To set or thrust in motion.

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

17. The space in the fuselage of a small airplane containing seats for the pilot - copilot - and sometimes passengers.

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

19. Design machines that fly.

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

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

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

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

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

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

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

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

28. Aircraft speeds under Mach 1.

29. The force that created by the effect of airflow as it passes over and under the wing.

30. A vehicle - missile - or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.

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

32. The ratio of inertial forces to viscous forces.

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

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

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

36. The relationship between the length and width of a wing.

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

38. 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.

39. The part of the airfoil that meets the airflow first.

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

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

42. 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.

43. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.

44. Aircraft speeds between Mach 1 and 5.

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

46. Aircraft speeds between Mach 10 and 25.

47. Houses the cabin - the cockpit and is a common attachment point for the other major components.

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

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

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