  • 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 to obvious but it re-enforces your understanding as you take the test each time.
1. An advertising film which promotes a product in an informative and supposedly objective style.

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

3. 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.

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

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

6. A glider designed for sustained flight.

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

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

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

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

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

12. Aircraft speeds under Mach 1.

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

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

15. 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.

16. Aircraft speeds between Mach 5 and 10.

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

18. 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.

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

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

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

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

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

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

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

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

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

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

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

30. Aircraft speeds between Mach 1 and 5.

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

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

33. To set or thrust in motion.

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

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

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

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

38. 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.

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

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

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

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

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

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

45. The ratio of inertial forces to viscous forces.

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

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

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

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

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