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






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






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






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






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






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






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






8. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






20. The ratio of inertial forces to viscous forces.






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






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






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






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






25. 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.






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






27. 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.






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






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






30. Robotic aircraft - used extensively by the military.






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






32. Design machines that fly.






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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






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






47. Aircraft speeds under Mach 1.






48. Aircraft speeds between Mach 1 and 5.






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






50. Aircraft speeds between Mach 10 and 25.
