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

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

3. Design machines that fly.

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

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

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

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

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

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

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

11. The ratio of inertial forces to viscous forces.

12. Aircraft speeds under Mach 1.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

28. 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.

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

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

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

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

33. Aircraft speeds between Mach 10 and 25.

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

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

36. 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.

37. 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.

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

39. A glider designed for sustained flight.

40. Robotic aircraft - used extensively by the military.

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

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

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

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

45. Aircraft speeds between Mach 5 and 10.

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

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

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

49. To set or thrust in motion.

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