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

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

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

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

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

6. 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.

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

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

9. A glider designed for sustained flight.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

25. Aircraft speeds under Mach 1.

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

27. The ratio of inertial forces to viscous forces.

28. Aircraft speeds between Mach 5 and 10.

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

30. 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

48. Aircraft speeds between Mach 10 and 25.

49. 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.

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