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

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

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

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

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

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

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

8. Aircraft speeds between Mach 1 and 5.

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

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

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

12. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.

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

14. 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.

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

16. To set or thrust in motion.

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

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

19. The ratio of inertial forces to viscous forces.

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

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

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

23. The written text of a play - film - or broadcast.

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

25. Design machines that fly.

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

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

28. Robotic aircraft - used extensively by the military.

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

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

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

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

33. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.

34. 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.

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

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

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

38. Aircraft speeds between Mach 10 and 25.

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

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

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

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

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

44. Aircraft speeds between Mach 5 and 10.

45. 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.

46. A reduction in the chord of a wing as measured from the root to the tip of the wing.

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

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

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

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