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






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






3. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






10. 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.






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






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






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






14. 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.






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






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






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






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






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






20. Aircraft speeds under Mach 1.






21. Aircraft speeds between Mach 5 and 10.






22. To set or thrust in motion.






23. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






41. A glider designed for sustained flight.






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






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






44. Robotic aircraft - used extensively by the military.






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






46. 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.






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






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






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






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