AGK/POF Questions with Complete Correct Answers | Grade A+

How can turbulent air cause an increase in stalling speed of an airfoil? A. An abrupt change in relative wind. B. A decrease in angle of attack. C. Sudden decrease in load factor. Ans: An abrupt change in relative wind. What is the maximum allowable weight that may be carried on a pallet which has the dimensions of 76 × 74 inches? Floor load limit - 176 lb./sq. ft. Pallet weight - 77 lb. Tie-down devices - 29 lb. A. 6,873.7 pounds. B. 6,767.8 pounds. C. 6,796.8 pounds. Ans: 6,767.8 pounds. (The calculation is as follows: Pallet area: 76 × 74 = 5,624 sq. in. Pallet sq. ft.: 5,624 ÷ 144 = 39.056 sq. ft. Max. weight: 39.056 × 176 = 6,873.8 lb. Mweight:6,873.8-77-29=6,767.8lb.) What flight condition should be expected when an aircraft leaves ground effect? A. A decrease in parasite drag permitting a lower angle of attack. B. An increase in dynamic stability C. An increase in induced drag requiring a higher angle of attack. Ans: An increase in induced drag requiring a higher angle of attack. Why must the angle of attack be increased during a turn to maintain altitude? A. Compensate for loss of vertical component of lift. B. Increase the horizontal component of lift equal to the vertical component. C. Compensate for increase in drag. Ans: Compensate f
