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






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






3. 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.






4. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 10 and 25.






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






26. A glider designed for sustained flight.






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






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






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






30. 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.






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






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






33. Design machines that fly.






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






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






36. The ratio of inertial forces to viscous forces.






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






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






39. To set or thrust in motion.






40. Aircraft speeds under Mach 1.






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






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






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






49. 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.






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