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. 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.






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






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






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






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






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






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






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






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






12. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






20. 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.






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






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






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






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






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






26. Design machines that fly.






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






28. A glider designed for sustained flight.






29. The ratio of inertial forces to viscous forces.






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






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






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






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






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






35. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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