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

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

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

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

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

6. 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.

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

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

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

10. Aircraft speeds between Mach 10 and 25.

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

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

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

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

15. 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.

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

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

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

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

20. Robotic aircraft - used extensively by the military.

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

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

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

24. 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.

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

26. Design machines that fly.

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

28. Aircraft speeds between Mach 5 and 10.

29. The ratio of inertial forces to viscous forces.

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

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

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

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

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

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

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

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

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

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

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

41. Aircraft speeds under Mach 1.

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

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

44. To set or thrust in motion.

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

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

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

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

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

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