FAA Written Exam524 Questions with Correct Answers 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 mai ... n 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. Stabilator C Ailerons >>> A. Flaps The elevator controls movement around which axis? >>> Lateral. Which statement is true concerning primary flight controls? A. The effectiveness of each control surface increases with speed because there is more flow over them B. Only when all three primary flight controls move in sequence do the airflow and pressure distribution change over and around the airfoil. C. Primary flight controls include ailerons, rudder, elevator, and trim systems >>> A. The effectiveness of each control surface increases with speed because there is more flow over them. Which of the following is true concerning flaps? A. Flaps are attached to the leading edge of the wing and are used to increase wing lift. B. Flaps allow an increase in the angle of descent without increasing airspeed. C. Flaps are high drag devices deployed from the wings to reduce lift. >>> B. Flaps allow and increase in the angle of descent without increasing airspeed. Which device is a secondary flight control? A. Spoilers B. Ailerons C. Stabilators >>> A. Spoilers Trim systems are designed to do what? >>> They relieve the pilot of the need to maintain constant back pressure on the flight controls. The four forces acting on an airplane in flight are: >>> Lift, Weight, Thrust, & Drag When are the four forces that act on an airplane in equilibrium? >>> During unaccelerated flight.What is the relationship of lift, drag, thrust, and weight when the airplane is in straightand-level flight? >>> Lift equals weight. Thrust equals drag. Which statement relates to Bernoulli's principle? >>> Air traveling faster over the curve upper surface of an airfoil causes lower pressure on the top surface. The term "angle of attack" is defined as the angle... >>> between the wing chord line and the relative wind. Angle of attack is defined as the chord line of an airfoil and the... >>> Direction of the relative wind. The angle of attack at which an airplane wing stalls will... >>> Remain the same regardless of gross weight. As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will... >>> Remain the same regardless of altitude. In what flight condition must an aircraft be placed in order to spin? >>> Stalled. During a spin to the left, which wing(s) is/are stalled? >>> Both wings are stalled. How will frost on the wings of an airplane affect takeoff performance? >>> Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability. Why is frost considered hazardous to flight? >>> Frost spoils the smooth flow of air over the wings, thereby decreasing lifting capability. How does frost affect the lifting surfaces of an airplane on takeoff? >>> Frost my prevent the airplane from becoming airborne at normal takeoff speed. What is ground effect? >>> The result of inference of the surface of the earth with the airflow patterns about an airplane. Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at... >>> Less than the length of the wingspan above the surface. What must a pilot be aware of as a result of ground effect? >>> Induced drag decreases; therefor, any excess speed at the point of flare may cause considerable floating. Ground effect is most likely to result in which problem? >>> Becoming airborne before reaching recommended takeoff speed. [Show More]
