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 common reference point for the three axes of the aircraft.






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






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






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






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






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






7. To set or thrust in motion.






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






9. Aircraft speeds between Mach 10 and 25.






10. Aircraft speeds between Mach 5 and 10.






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






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






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






14. 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.






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






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






17. 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.






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






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






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






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






22. A glider designed for sustained flight.






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






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






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






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






27. 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.






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






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






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






31. Aircraft speeds between Mach 1 and 5.






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






33. 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.






34. Design machines that fly.






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






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






37. The ratio of inertial forces to viscous forces.






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






39. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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