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






2. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






10. 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.






11. Design machines that fly.






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






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






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






15. 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.






16. To set or thrust in motion.






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






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






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






20. 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.






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






22. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






36. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






43. A glider designed for sustained flight.






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






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






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






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






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






49. Aircraft speeds under Mach 1.






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