Subject : engineering
Instructions:
  • 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 capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






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






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






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






5. A glider designed for sustained flight.






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






7. Design machines that fly.






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






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






10. 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.






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






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






13. Aircraft speeds between Mach 10 and 25.






14. 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.






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






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 1 and 5.






25. To set or thrust in motion.






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






27. 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.






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






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






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






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






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






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






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






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






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






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






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






39. 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.






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






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






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






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






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






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






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






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






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






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






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