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






3. Aircraft speeds under Mach 1.






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






5. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






11. 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.






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






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






14. 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.






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






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






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






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






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






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






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






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






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






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






25. The ratio of inertial forces to viscous forces.






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






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






28. 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.






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






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






31. Design machines that fly.






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






33. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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