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

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

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

4. Design machines that fly.

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

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

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

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

9. Robotic aircraft - used extensively by the military.

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

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

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

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

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

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

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

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

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

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

20. 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.

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

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

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

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

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

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

27. Aircraft speeds between Mach 10 and 25.

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

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

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

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

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

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

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

35. Aircraft speeds between Mach 1 and 5.

36. A glider designed for sustained flight.

37. 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.

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

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

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

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

42. Aircraft speeds between Mach 5 and 10.

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

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

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

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

47. 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.

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

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

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