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






4. The ratio of inertial forces to viscous forces.






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






6. 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.






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






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






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






10. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






20. To set or thrust in motion.






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






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






23. 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.






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






25. 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.






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






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






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






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






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






31. 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.






32. Aircraft speeds between Mach 10 and 25.






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






34. 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.






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






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






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






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






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






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






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






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






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






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






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






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






47. A glider designed for sustained flight.






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






49. Aircraft speeds under Mach 1.






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