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

2. Aircraft speeds between Mach 10 and 25.

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

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

5. 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.

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

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

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

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

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

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

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

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

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

15. Aircraft speeds between Mach 1 and 5.

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

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

18. 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.

19. Design machines that fly.

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

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

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

23. To set or thrust in motion.

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

25. 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.

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

27. The ratio of inertial forces to viscous forces.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

47. The study or practice of travel through the air.

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

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

50. 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.
