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






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






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






5. The ratio of inertial forces to viscous forces.






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 straight line through the center of gravity of the aircraft and at 90






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






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






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






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






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






13. 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.






14. 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.






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






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






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






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






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






20. 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.






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






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






23. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






30. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






41. Aircraft speeds under Mach 1.






42. Design machines that fly.






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






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






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






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






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






48. Aircraft speeds between Mach 1 and 5.






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






50. To set or thrust in motion.
