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






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






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






4. 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.






5. Aircraft speeds between Mach 10 and 25.






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






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






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






9. The ratio of inertial forces to viscous forces.






10. 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.






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






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






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






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






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. 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.






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






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






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






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






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






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






23. Aircraft speeds under Mach 1.






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






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






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






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






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






29. A glider designed for sustained flight.






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






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






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






33. Robotic aircraft - used extensively by the military.






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






35. To set or thrust in motion.






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






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






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






39. Aircraft speeds between Mach 5 and 10.






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






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






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






43. 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.






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






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






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






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






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






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






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