CHAPTER 6 ALL ABOUT DRAG (ATPL OXFORD)questions & answers rated A+ 2023/2024

CHAPTER 6 ALL ABOUT DRAG (ATPL OXFORD)What is the effect on total drag of an aircraft if the airspeed decreases in level flight below that speed for maximum L/D? a. Drag increases because of increased induced drag. b. Drag decreases because of lower induced drag. c. Drag increases because of increased parasite drag. d. Drag decreases because of lower parasite drag. - correct answers a. Drag increases because of increased induced drag. By changing the angle of attack of a wing, the pilot can control the airplane's: a. lift and airspeed, but not drag. b. lift, gross weight, and drag. c. lift, airspeed, and drag. d. lift and drag, but not airspeed. - correct answers c. lift, airspeed, and drag. What is the relationship between induced and parasite drag when the gross weight is increased? a. Parasite drag increases more than induced drag. b. Induced drag increases more than parasite drag. c. Both parasite and induced drag are equally increased. d. Both parasite and induced drag are equally decreased. - correct answers b. Induced drag increases more than parasite drag. In theory, if the airspeed of an airplane is doubled while in level flight, parasite drag will become: a. twice as great.
