  • 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 angle formed by the wing chord line and the relative wind.

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

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

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

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

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

7. The ratio of inertial forces to viscous forces.

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

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

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

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

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

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

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

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

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

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

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

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

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

21. 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

38. Aircraft speeds between Mach 10 and 25.

39. 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.

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

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

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

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

44. Robotic aircraft - used extensively by the military.

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

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

47. To set or thrust in motion.

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

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

50. 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.
