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






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






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. 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.






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






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






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






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






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






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






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






12. A glider designed for sustained flight.






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






14. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






24. Aircraft speeds under Mach 1.






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






26. 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.






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






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






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






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






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






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






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






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






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






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






37. Robotic aircraft - used extensively by the military.






38. To set or thrust in motion.






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






45. Aircraft speeds between Mach 1 and 5.






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






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






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






49. 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.






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