Aviation Questions and Answers Rated A+ fuselage the central body of an airplane that is designed to accommodate the crew and passengers (or cargo) flaps a movable airfoil that is part of an aircraft wing, used to increase lift slats protrusions from the leading edge of a wing that, when combined with the flaps, result in a significant increase in lift spoiler a hinged airfoil on the upper surface of an aircraft wing that is raised to reduce lift and increase drag (commonly use...

Airfoil - ANSWER-A structure or body which produces a useful reaction to air movement. Chord Line - ANSWER-An imaginary straight line from the leading edge to the trailing edge of an airfoil. Relative Wind - ANSWER-The wind felt by an airfoil (Parallel and in the opposite direction to the flight path of the airfoil). Angle of Attack - ANSWER-The angle between the chord line of the airfoil and the relative wind. Angle of Incidence - ANSWER-The angle at which a wing is attached to the ...

Gleim Private Pilot FAA Knowledge Test Guide Gleim Private Pilot FAA Knowledge Test Guide What is one purpose of wing flaps? To enable the pilot to make steeper approaches to a landing without increasing the airspeed. One of the main functions of flaps during approach and landing is to: Increase the angle of descent without increasing the airspeed. What is the purpose of the rudder on an airplane? To control yaw. Which is not a primary flight control surface? A. Flaps B. Stabilat...

The angle between the chord line of a wing or airfoil and the direction of the relative wind or airflow is called the (a) angle of pitch (b) degree of roll (c) angle of deflection (d) angle of attack - Answer- (d) angle of attack A conventional fixed-wing aircraft is controlled around its longitudinal axis by means of the (a) ailerons (b) elevators (c) rudder (d) trim tab - Answer- (a) ailerons Two statute miles are equal to (a) 2.0 nautical miles (b) 1.74 nautical miles (c)...

Who certifies and regulates pilots? CORRECT ANSWER Federal Aviation Administration The four forces acting on an airplane in flight are CORRECT ANSWER Lift Weight Thrust Drag Which statement relates to Bernoulli's principle? CORRECT ANSWER Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface The two parts of the wing which maneuver the aircraft are the CORRECT ANSWER Flaps from the wing root to the midpoint and the ailerons from th...

NIFE AERO QUESTIONS AND ANSWERS RATED A+ What is a vector? direction and magnitude What is air density? Total mass of air particles per unit volume. m/v What is a moment? Force that is moved some distance. What are the requirements for an airplane to be in equilibrium flight? Sum of all forces and all moments around the center of gravity are equal to 0 Can equilibrium flight be achieved in a turn? No. Acceleration is occurring. There are moments What are the requirements for an a...

You climb to 17,000 feet in a turbocharged airplane and maintain the same true airspeed as you had been maintaining near sea level. What would you expect to observe about pitch attitude under these conditions? A-to maintain altitude, you need to maintain a more nose-high attitude because of the reduced air density compared to sea level B-to avoid climbing, you need to maintain a more nose-low attitude because of the reduced drag compared to sea level C-to maintain altitude, you need to ma...
