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






2. Aircraft speeds between Mach 10 and 25.






3. 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.






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






5. 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.






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






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






8. To set or thrust in motion.






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






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






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






12. A glider designed for sustained flight.






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






14. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






24. Aircraft speeds under Mach 1.






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






26. 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.






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






28. Design machines that fly.






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






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






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






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






33. 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.






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






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






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






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






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






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






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






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






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






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






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






45. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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