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

2. 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.

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

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

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

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

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

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

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

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

11. Aircraft speeds under Mach 1.

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

13. To set or thrust in motion.

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

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

16. A glider designed for sustained flight.

17. Aircraft speeds between Mach 5 and 10.

18. Robotic aircraft - used extensively by the military.

19. Aircraft speeds between Mach 1 and 5.

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

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

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

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

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

26. Aircraft speeds between Mach 10 and 25.

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

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

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

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

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

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

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

34. 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.

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

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

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

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

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

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

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

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

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

44. 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.

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

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

47. 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.

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

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

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