  • 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 glider designed for sustained flight.

3. 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.

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

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

6. 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.

7. Aircraft speeds between Mach 5 and 10.

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

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

10. 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.

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

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

13. 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.

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

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

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

17. A rear vertical stabilizer that controls side- to- side or yawing motion of the aircraft nose.

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

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

20. The ratio of inertial forces to viscous forces.

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

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

23. Robotic aircraft - used extensively by the military.

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

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

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

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

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

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

30. Aircraft speeds under Mach 1.

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

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

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

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

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

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

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

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

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

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

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

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

43. To set or thrust in motion.

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

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

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

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

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

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

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