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






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






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






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






5. A glider designed for sustained flight.






6. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






15. To set or thrust in motion.






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






17. Aircraft speeds under Mach 1.






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






19. 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.






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






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






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






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






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






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






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






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






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






29. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






38. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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 part of the airfoil that meets the airflow first.






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






46. Design machines that fly.






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






48. 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.






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






50. 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.
