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






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






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






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






5. 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.






6. Robotic aircraft - used extensively by the military.






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






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






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






10. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






18. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






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






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






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






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






40. A glider designed for sustained flight.






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






42. Aircraft speeds between Mach 1 and 5.






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






44. 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.






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






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






47. To set or thrust in motion.






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






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






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