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






3. 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.






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






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






6. The ratio of inertial forces to viscous forces.






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






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






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






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






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






12. 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.






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






14. Robotic aircraft - used extensively by the military.






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






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






17. Aircraft speeds under Mach 1.






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






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






20. 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.






21. A glider designed for sustained flight.






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






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






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






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






26. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






35. To set or thrust in motion.






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






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






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






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






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






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






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






43. 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.






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






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






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






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






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






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






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