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






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






3. 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.






4. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






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






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






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






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






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






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






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






25. 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.






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






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






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






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






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






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






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






33. Design machines that fly.






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






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






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






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






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






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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