Private Pilot: FAA Written Exam Questions And Answers

What is one purpose of wing flaps? - Answer - 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... - Answer - Increase the angle of descent without increasing the airspeed What is the purpose of the rudder on an airplane? - Answer - To control yaw Which is not a primary flight control surface? A. Flaps B. Stabilator C Ailerons - Answer - A. Flaps The elevator controls movement around which axis? - Answer - Lateral Which statement is true concerning primary flight controls? A. The effectiveness of each control surface increases with speed because there is more airflow 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. - Answer - A. The effectiveness of each control surface increases with speed because there is more airflow 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. - Answer - B. Flaps allow an increase in the angle of descent without increasing airspeed Which device is a secondary flight control? A. Spoilers B. Ailerons C. Stabilators - Answer - A. Spoilers Trim systems are designed to do what? - Answer - 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: - Answer - Lift, Weight, Thrust, and Drag When are the four forces that act on an airplane in equilibrium? - Answer - During unaccelerated flightWhat is the relationship of lift, drag, thrust, and weight when the airplane is in straightand-level flight? - Answer - Lift equals weight Thrust equals drag Which statement relates to Bernoulli's principle? - A
