ATPL - Principles of Flight Questions and Answers Latest Version Already Passed What is the primary factor affecting an aircraft's lift production? A) The weight of the aircraft B) The fuel type used C) The angle of attack and airspeed D) The color of the aircraft What happens when an aircraft exceeds the critical angle of attack? A) It gains extra lift B) The drag decreases significantly C) The aircraft stalls D) The engine power increases How does increasing altitude affect the indicated airspeed at which a stall occurs? A) The stall speed remains the same B) The indicated stall speed remains similar, but the true stall speed increases 2 C) The stall speed decreases due to lower air density D) The stall speed is unaffected by altitude What is the purpose of vortex generators on an aircraft’s wing? A) To increase fuel efficiency B) To eliminate wake turbulence C) To delay airflow separation and reduce the risk of stall D) To improve passenger comfort What is the primary effect of deploying flaps during takeoff? A) It increases lift at lower speeds B) It decreases aircraft weight C) It improves fuel consumption D) It reduces drag significantly What aerodynamic force opposes thrust? A) Drag B) Lift 3 C) Weight D) Pressure How does a swept-wing design affect an aircraft's performance? A) It reduces stall speed B) It delays the onset of shockwaves at high speeds C) It increases induced drag D) It makes the aircraft more stable at low speeds Why do commercial jets typically cruise at high altitudes? A) To avoid bird strikes B) To reduce drag and increase fuel efficiency C) To improve passenger comfort D) To maintain radio communication What happens to the center of pressure as an aircraft’s angle of attack increases? A) It moves rearward along the wing B) It moves forward along the wing 4 C) It remains stationary D) It shifts to the fuselage What is the main reason for using winglets on modern aircraft? A) To reduce induced drag and improve fuel efficiency B) To provide additional lift C) To increase aircraft weight D) To act as a backup control surface How does ground effect influence an aircraft during takeoff and landing? A) It reduces induced drag, making the aircraft feel like it is floating B) It increases drag, making landing difficult
